What a difference some rain can make! The outlook has completely turned around following good rainfall right across the Mallee region and all of a sudden, we are facing a promising season. Fortunately this strategy has paid off - there rain we’ve received so far has resulted in good seed bed moisture, germination, and a prediction from the Bureau of Meteorology of a 75% chance of above average rainfall in the coming months. All eyes will be on the sky as we see how the season rolls out from here, but already you can see the region bouncing back. There’s some great crops on show across the region, particularly down around Woomelang and Lascelles. Birchip hasn’t had as much rain as other areas, but I’m reliably informed that the outlook is still positive.

It never ceases to amaze me how quickly things can change. When the last edition of the Mallee Farmer came out earlier this year, the forecast for the season wasn’t very positive. This was followed by yet another poor Autumn break, on top of a very dry summer, and little or no sub-soil moisture. Now we are into the fifth edition of the Mallee Farmer and more than half way through the year. Despite the dry start, many farmers backed themselves for a reasonable season and thousands of hectares of crops were dry sown.

Seasonal Conditions

What a turnaround! From a summer and autumn that delivered almost no rain and had many on-edge, to the first days of June that began the true seasonal break. By

Rob Sonogan, AGRIvision Consultants PTY LTD

in many instances control activities had to be carried out. The crops are now well on track!

Extensive dry-sowing (some into moisture) had about 80% of crop sown prior to the early June dumping of some 40 to 90mm across the Mallee. Many had made the decision to reduce their area sown to canola and much discussion had occurred over concerns with chemical residue plant-back.

The dry sowing always presents some complexities and 2013 was no exception. Irregular germination due to soil moisture variability had some lighter soils germinating first and in some heavier soils the crops had difficulty emerging when it did eventually rain (especially canola).

The current scene

Weeds and more weeds

In the last week of June (time of writing this article) the Mallee looks fantastic and has responded as only the Mallee can! The plant-back concerns were greatly assisted by having the options of ClearField varieties available to substitute conventional lines. Some minor Lontrel damage has been reported but significant problems appear to have been avoided by good planning and understanding the challenge the extremely dry summer presented us. The crops of canola, vetch and lentils were subjected to early mite attack and

With no summer weed control it was to be expected that weeds would be an issue. However, for many paddocks the sheer extent of problematic weeds is a real management task that is underway and will continue well into the season. Brome grass has raised its head with vigour and crop-topping soon no doubt will play a major part in its control. Your agronomist/advisor can assist you to understand the issues involved in the sprays to use and crops that are registered.

In-crop soil testing for Nitrogen (N)

Correctly, minimal soil testing for N was carried out pre-sowing due to the unusually dry conditions. With later germinations and sowing carried out it may still be opportune to have a deep soil test done to accurately determine how much, if any, N is required. It can be a very expensive decision to topdress (or to not topdress) based upon gut feeling. It is always a good agronomic test to also leave a strip as a control, so when harvesting you can check the economic response to both yield and quality.

And for the rest of the season?

The current rainfall outlook is for a reasonable chance of getting above average rainfall for July, August and September. If this eventuates the season may conclude successfully which would be a relief after such a shaky start. It never ceases to impress me the flexibility that Mallee farmers exhibit in responding to changing circumstances and to information given, and of the three certainties in life, -taxes, death and change; that of long range weather forecasting is still not close to becoming the fourth!

Nitrogen and sulphur decisions It is now time to review nitrogen (N) and sulphur (S) budgets established earlier in the year. The recent rain allows planning of nitrogen strategies with more confidence. Organise supplies now and be ready for the next rain front. By

Kent Wooding, AGRIvision Consultants PTY LTD Nitrogen and sulphur decisions’ should be made from a good level of understanding of yield potential and existing levels of nutrients in the soil. Soil sampling in-crop to assess N & S levels should be carried out on at least a few “indicator” paddocks on the farm if they were not carried out prior to sowing. Review your top dressing budgets/ plans and re-assess yield potential. We should be looking to supply sufficient N for a realistic and achievable yield and not maximum N for maximum yield. Be ready to respond to the season. That may mean gearing up for more N if the season is favourable or locking the gate if the rain stops. Nitrogen applications should first be targeted at the paddocks likely to provide the best response or have the greatest

need. Set your priorities with your adviser now. Cereals and canola back on cereal stubbles and paddocks with a poor legume history are usually a good place to start.

The key products

Urea (46:0:0:0) - The standard product used in most situations where nitrogen is required. It is the cheapest source of applied nitrogen. Where canola has been spread with gypsum or sulphur applied up-front, further N applications are likely to be straight urea. GranAm/SOA (21:0:0:24) - this product is sulphate of ammonia. It contains 21% nitrogen and 24% sulphur. Quality varies so ensure you select the right product for the right job. Handling and spreading characteristics are features to check. The best quality SOA products behave and look much the same as urea but may attract more moisture in storage than urea. Due to the high % of sulphur in the product putting out high rates of SOA is

an expensive way to apply nitrogen. The sulphur in SOA generally costs around $1.00 per kg of S. Therefore if you want to apply 15kg of sulphur onto a paddock it will probably cost you around $15/ha more than what it would cost to apply straight urea. We often plan to use SOA in a blend with urea as generally we are chasing more N than S and to apply high rates of N with SOA is too expensive.

Other products

Slam (19:1:0:23) - this is an SOA product which looks more like MAP than urea. It may be ok for spreading with spinners but it is not suggested to run it through an air seeder. Slam contains 1% phosphorus so this may be a bonus when considering the price. Do not blend this with urea. Stimulus (30:0:0:15) & ExtraSul (32:0:0:13) - These products are an SOA + Urea blend providing a good mix of N & S. Run stimulus on canola or when chasing more S and ExtraSul on cereal or when less S is required. Other SOA/Urea Blends – SOA and Urea can be blended at the plant to achieve a desired ratio of N & S. They can be blended up to suit a specific situation or paddock.


The

Mallee Farmer UAN (42:0:0:0 as liquid) – Easy and timely to apply with your own boom spray. At current levels UAN is roughly 50% more expensive than urea. UAN may have a fit when using low rates to give crops a short term boost (e.g. crops stressed by herbicide or disease and need a kick). It may be too expensive to consider as a single means to deliver bulk amounts of nitrogen but may be a good option if you have the man power to have one person spaying UAN and another spreading urea or SOA just prior to a rain front. At low rates, UAN can be applied with some herbicides to help with timing and application efficiency.

to a canola crop in the Mallee. Heavier soils or paddocks which have tested high for sulphur (e.g. had gypsum in the last couple of seasons) may not need S. Cereals do not have a high demand for sulphur be we still need the nutrient. We often see sulphur deficiency on light sandy soils. If your soils are S deficient, they are unlikely to respond to additional N. On light sandy soils plan to apply around 8-10kg/ha of sulphur to ensure that the wheat is not deficient. Crop requirements for sulphur vary. Wheat requires 4kg S/t. A 2t/ha wheat crop will use 8kg/ha S. Canola requires 20kg S/t. A 1.2t/ha canola crop will use 25kg/ha S. These figures are based on crop removal and nutrient efficiency.

Liquid urea or SOA/Urea Liquid blends. There are various liquid solutions of urea and or Urea/sulphate of ammonia. These products may be an option if you prefer applying a liquid and you require sulphur. These liquids may provide some growers with logistical benefits but there are generally no additional agronomic advantages.

Sulphate sulphur leaches readily so applying smaller amounts often may be more beneficial. The sulphur present in starter fertilises like MES and MESZ often provide a sufficient starter S and a trickle of available S throughout the season.

Where do I need sulphur and how much?

There is a lot of talk and research to support the process called canopy management. This has some scientific merit and is easy to manage in small plot trials. On farm over a large area we cannot afford perfect nitrogen application

The amount of sulphur you need to apply depends on the soil type and what quantity of S is present in the soil (refer to soil tests). As a general rule you would look to apply roughly 15kg of S

Timing of nitrogen

timing. We have to make the most of the two or three good rainfall events during the season. It may be more beneficial to the crop and farm returns to be slightly early and have the N out just prior to a rain event than wait for the perfect timing and then receive insufficient rain. Sandy soils often require more N early in the season to ensure the cereals produce sufficient tillers. Regardless of the timing we must be flexible and willing to respond to the season. We must always ensure we are matching nitrogen and sulphur requirements to a realistic yield estimate and this is a moving target. That may mean gearing up for more N if the season is favourable or locking the gate if the rain stops.

Recycled drums at MRCC depot.

Cleaning up the farm and the environment The Australia-wide drumMuster program commenced in 1999 and to date has saved over 21 million used agvet chemical containers (around 26,400 tonnes) from going into landfill, delivering benefits to both the industry and the broader Australian public. By

John Knight, drumMUSTER and ChemClear. drumMUSTER is a stewardship program that collects and recycles used containers for crop production and on-farm animal health chemicals. Eligible non-returnable, metal and plastic containers are cleaned of residue by farmers and delivered to one of more than 874 collection sites across Australia. Supported by 370 councils throughout Australia, drumMUSTER is funded by a levy of four cents per litre or kilogram of

participating agvet chemicals at the point of sale. The drumMUSTER program is managed by AgStewardship Australia and daily operation of the program is delivered by Agsafe Limited. The program was designed to enable non-returnable used chemical containers to be brought back into various locations for recycling purposes at no cost to the users. The current range of drum sizes accepted are one to 205 litres. The program can’t accept returnable enviro-drums, 1000L shuttles, or the 15L cardboard box with the plastic liner inside.

There is no cost to deposit drumMUSTER logo chemical containers at any of the drumMUSTER sites, providing there is no chemical residue present inside the containers. It is important that all chemical containers are properly rinsed and cleaned with water after use, and delivered free of any chemical or liquid with the lids removed. The collected used chemical containers are recycled into a variety of new plastic products such as: conduit, concrete chair bars, wheelie bins, plastic posts, tables and chairs, and bollards. Farmers in the Mallee and northern Wimmera regions of Victoria have been great supporters of the drumMUSTER program delivering their empty clean containers to the various drumMUSTER cages located at many of the region’s council-managed transfer stations or landfill sites. Since 1999 councils in these regions have collected 1.63 million drums.


The

Mallee Farmer Additional community benefits

An initiative of drumMUSTER has been the formation of community collection groups in partnership with local community organisations such as local schools, tennis clubs, football and netball clubs, town community social groups, Lions Clubs, and CFA groups. This initiative was developed in recognition of the fact the some agvet chemical users are too far from their closest drumMUSTER collection site and has been very successful in the Mallee and northern Wimmera regions. Community collection groups involved receive 25 cents for every drumMUSTER logo container collected, providing community organisations with extra income for their projects. In addition, it means that more containers are collected under the drumMUSTER program and local properties are being cleaned up of unwanted stored chemical containers.

Getting rid of unwanted farm chemicals

The ChemClear program is designed for the collection of unwanted chemicals and also operates Australia-wide. The program is a free service for any drumMUSTER logo containers with current registration or within two years of that registration being expired. This is called the Group 1 classification; to be eligible containers must have the drumMUSTER logo visible and chemical must be in its original container. A Group 2 classification is for containers that have had the product label removed or the contents of the container are unclear. Collection of these containers will still be undertaken by the ChemClear program however, a fee will apply for the service.

EMAP – creating positive change in the Mallee

For the last eight years the Environmental Management Action Planning (EMAP) program has helped Mallee farmers to plan for a sustainable and productive future. By

Elizabeth Gosling, Mallee CMA EMAP is a skills, knowledge and planning program tailored to Mallee dryland farmers. Based on local environmental and agricultural issues, the program helps farmers to plan and carry out works to increase the sustainability, productivity and profitability of their farm. The program began in 2005 in the Tyrrell Basin and has since included areas around Ouyen, Millewa-Carwarp, Underbool, Murrayville, Hopetoun and Birchip.

6

How EMAP works

The program is built around a series of workshops on local environmental issues and sustainable agriculture, supported by one-on-one case management and follow up farm visits. The workshops and farm visits help equip farmers with the skills, knowledge and confidence to plan and carry out actions that improve the environmental and productive values of their property. These actions include on-ground works and changes in management practices that aim to improve the environmental condition of the farm, the health of its soils and the running of the farm business.

Key achievements: • 1.1 million hectares of land covered by farm plans – 46 per cent of agricultural land in the Mallee; • 497 farming families have taken part in the program; • Over 2,000 maps have been produced; • More than 110 workshops held; • Landholders have mapped over 7,900 works; • Proposed works cover over 200,000 hectares, 2,890 kilometres, and 860 sites on private land.


The

Mallee Farmer All proposed works are mapped on poster-sized aerial imagery of their farm; these maps then become a handy reference and planning tool.

Mapping actions

At the workshops, landholders are encouraged to think of environmental actions or works they would like to carry out; other types of actions, such as those that are production and business related are also captured. Actions are grouped into six categories: • Biodiversity; • Pest plants, animals and diseases; • Salinity; • Water management; • Whole farm planning (including soil health and nutrition); • Safety and wellbeing. Most of the actions that EMAP participants have mapped relate to whole farm planning and biodiversity as seen in the chart to the right. Importantly, planning has led to action. For example, almost half (47 per cent) of the area actions (such as hectares identified for rabbit control, revegetation and salinity works) mapped between 2005 and 2009 have been completed.

Graduate EMAP - the learning continues

After landholders complete EMAP they can enter the graduate program, where they receive on-going support from a local case manager. Case managers link farmers to technical advice for on-ground works and let them know of any funding available to assist with their planned actions. Follow up training is also offered through workshops and field days. EMAP graduates also have the chance to review and update their plans every three to four years. This helps ensures that maps remain a useful and current planning tool for farmers.

Case study – Ian McNabb

Ian McNabb operates a mixed cropping, sheep and cattle farm at Carwarp (20km south of Mildura) with his son, David. Ian is no stranger to salt and its associated land management problems – a large area of his 2,400 hectare property is subject to salinity. Much of this salinity is natural, but some area have become increasingly saline through past farming practices and clearing. By taking part in EMAP, Ian and David could identify these salt-affected

Mapped actions by EMAP participants.

areas and plan actions to address the associated salinity issues. Capturing their vision to bring salt-affected land back into production, the McNabbs have mapped 220 hectares of salinity abatement actions and 24 hectares of biodiversity actions. The Mallee Catchment Management Authority (CMA) has helped Ian and David to put their plan into action by contributing to 136 hectares of revegetation for salinity control. Incentives have also helped them to fence saline areas so they can be managed separately. The success of these works is already evident; older saltbush plantings have lessened salt pans to the point where plantings can now grow in areas previously thought to be unviable for saltbush.

“I could see my property getting worse. It was a case of either go and get more land, or fix up what I had. A lot of neighbours thought I was mad fixing it up. I couldn’t see an alternative. Now it is saving so much of my country. If I hadn’t participated in EMAP, I would have a lot of salt pans and would have had to buy more land to be able to stay farming.” Ian McNabb To get the full story on EMAP look out for the new promotional booklet, which celebrates EMAP’s achievements of the last eight years.

Rosella wheat on April 2, 2013.

Growing winter wheat on summer rain

In a bid to identify how farmers might make better use of summer and early autumn rain, researchers at Birchip Cropping Group (BCG) have established a trial that will compare the early grazing and yield potential of winter wheat varieties grown in the Mallee. By

Dannielle McMillan and Justine Severin, BCG The BCG 2013 sowing program got off to a very early start this year with the first research trial being sown on February 25. With 54mm of rain recorded at Curyo (25kms north-west of Birchip) on February 14, BCG took the opportunity to test the performance of long season wheat varieties when sown very early in the Mallee. In recent years the Mallee has experienced a decline in April to May rainfall, which hinders the ability for spring wheat to establish when sown during the traditional seeding period (late April to May). If this trend continues, and healthy rainfall events occur during summer and late autumn (as they have in recent years), growers could benefit from the inclusion of some longer season winter wheat varieties in their rotation.

8

The trial will look at how effectively winter wheat varieties use summer and early autumn rain and their early grazing and yield potential. The eight wheat varieties being compared in this trial include Rosella, Wedgetail, Revenue, Whistler, Wylah, CSIROW7A, CSIROW8A (CSIRO experimental lines) and YW443 (a Chinese winter wheat). During the season each variety’s growth, feed quality and response to grazing will be measured, with grain quality and yield measured at the end of the season.

Managing winter wheats

Growing winter wheat varieties could be used as a risk management tool as they have a flexible sowing period of two months (compared with only two weeks for spring varieties) and a vernalisation period which allows for earlier sowing without frost risk. Early sowing allows the crop to take advantage of stored soil water from late summer and early autumn rain.

For mixed farmers, winter wheat varieties could also provide a nutrition source for livestock, particularly at times when there is commonly limited available feed (after a dry autumn). Because they have a longer tillering period (prior to growth sage 30) than their spring wheat counterparts, winter wheat varieties can be grazed longer without a significant reduction in yield. There is also the theory that long season wheats produce deeper roots and this, coupled with their longer growing season, can lead to a greater proportion of water being transpired, increasing drymatter and, potentially, yields. However, it is imperative that the stored soil moisture is present, and it is available to at least 30cm within the soil profile, when sowing long season wheat early. Growers should aim to sow winter wheat between late February and late April. Currently there are no winter wheat varieties specifically adapted for the Mallee and Wimmera region for early sowing. Rosella was the highest yielding winter wheat in a 2012 BCG trial being most suited to the Mallee region. However, with Rosella being released over 27 years ago it lacks in grain yield when

compared to contemporary spring wheats. There are some varieties currently being developed in this area.

2012 results

Last season BCG conducted a research trial examining the performance of very early sown wheat varieties, their early grazing potential and ability to recover from grazing. The varieties examined included slow maturing spring wheats (Bolac and Forrest); a fast maturing winter wheat (Rosella ); a slow maturing winter wheat (Wedgetail); and Yitpi â&#x20AC;&#x201C; a mid-maturing spring wheat variety most commonly grown in the Mallee. All varieties were sown at Birchip on March 14, after 56mm of rain in late February and early March, ensuring even emergence. Plants grew well on this stored water, despite no further rain falling until late May. Frosts (air temp. <2°C) were very common throughout the 2012 growing season, occurring on 78 occasions. Of the varieties tested in this trial, the winter wheat Rosella yielded better than all other varieties except the midmaturing spring wheat Yitpi (Table 1). Grazing and variety had no effect on protein (site average 12%), but Bolac and Forrest had higher levels of screenings than the winter wheats and Yitpi.

This trial showed that opportunities exist for Mallee and Wimmera growers to plant winter wheats in response to late summer and early autumn rain. While winter wheat yields in this trial were less than those achieved by spring wheats, it was noted that the varieties trialled were not specifically adapted to the Mallee and Wimmera. The results motivated further investigation in 2013.

Winter wheats in 2013

After sowing on February 25, emergence of the 2013 winter wheat trial was rapid and fairly even with Rosella slightly more advanced that the other varieties. The next decent rainfall (after 54mm in February) didnâ&#x20AC;&#x2122;t occur until the start of June and the trial did exhibit signs of moisture stress. While all varieties handled the extended dry conditions through March and April surprisingly well, by May they were clearly in need of a good drink. Visually, Rosella seemed to survive the dry conditions better than the other varieties which, by May 2, were displaying curled leaves and some faint purpling. A rainfall of 12.5mm in May saw the plots recover to varying degrees, with Rosella and Wedgetail appearing the most resilient. With crop growth now excelling after further rainfall events (approx. 55mm for June), the plots will undergo grazing.

New industry network channels top on-farm issues to GRDC NEW small-scale activities to address specific regional on-farm issues will be rolled out in the Grains Research and Development Corporation’s (GRDC) Southern Region low rainfall zone with the aim of fast-tracking research progress. By

Deanna Lush, GRDC Early last year, the GRDC established Regional Cropping Solutions Networks (RCSNs). There are four networks, one each for low, medium and high rainfall and irrigation farming systems, represented by 52 growers, advisers and researchers. The Low Rainfall Zone RCSN is coordinated by Nigel Wilhelm. Nigel says all group members have extensive experience and networks across the low rainfall zone of south-eastern Australia and includes a spread from Streaky Bay on the west coast of South Australia to

Condobolin in central NSW, with farming, consulting and research experience. The group met earlier this year to revise and update its list of current issues for their rainfall zone. These include: • More profitable/less risky ways to manage disease, pest nutrition and weed issues after cereals. The group would like to see research that produces more profitable and less risky break options and cheap, reliable, management techniques. Such tools are increasingly important to complement chemical controls which are running into more and more resistance issues. • Poorly integrated livestock and cropping enterprises. While

not entirely an issue for GRDC, research has shown that improving the profitability of livestock enterprises and growers’ stock management skills can improve outcomes for mixed systems, which are still widespread and well suited to low rainfall environments. • Over-dependence on agrichemicals. Increasing incidence of resistance in weeds and pests to agrichemicals is making them less effective. Farming systems in the future must be less reliant on chemical inputs for maintaining fertility and controlling weeds, pests and diseases. • Under-resourced and reactive weed science. With emerging weed control issues, the group would like to see an ongoing industry resource to anticipate new weed issues, monitor herbicide resistance, weed ecology and develop cost-effective control options. • Succession planning for RD&E expertise.

struggling to attract the interest of students at all levels of education and this must be reversed to ensure an innovative R,D&E sector in the future. Poor business management skills. A key area to develop better business skills is in risk and responsiveness in business structures to cope with climate variability to combat lost profit and increased risk. Declining soil fertility. Australia’s older soils with low inherent fertility mean this is an especially acute issue, which for the low rainfall agriculture is currently being displayed in low nitrogen reserves. Growers need better quantification of adverse effects of N imbalances in LRZ farming systems. Poor sandy soil productivity. More research is needed to identify the cause of poor productivity on sandy soils to realise higher water use efficiencies. CTF benefits in low rainfalls. Controlled traffic is a system claiming many benefits to intensive cropping systems but its level of adoption is very low in the LRZ.

“Many of these concepts have been worked through in close detail, identifying what we believe the key outcomes growers would want addressed onfarm and which will be considered in the GRDC Southern Panel’s future investment process,” Nigel said. “Regional priority weeds impacting low rainfall zone properties were also identified. “Some of these issues are already being targeted by the GRDC and that is the next step in the process, to identify the gaps and how they can be addressed.” Nigel says while not all of the issues can be addressed quickly with short-term investments, there are some issues where there are opportunities to move quickly. “Small-scale regional investments, called ‘fast track projects’, will allow for an immediate response to issues experienced during the growing season so we can get information back to growers as quickly as possible,” he said. The fast-track projects are designed to be very local for growers with specific questions. Already, one fast-track project has been conducted last year on herbicide resistance. The project aims to quantify levels of herbicide resistance in annual ryegrass and common sow thistle and map its distribution in the Griffith region of New

This will address knowledge gaps in how much seed was spread from farm to farm and resistance levels in key weed species common in low rainfall environments. Rather than conducting a random survey, seed will be tested which growers have identified as potentially resistant, along with a record of management practices used in the paddock.

Victorian Food & Fibre Marketing Cooperatives Grants Program The Philosophy of ‘Cooperate to Compete’ is gaining acceptance, especially in regional areas. The Victorian Government’s Food & Fibre Marketing Cooperatives Grants Program (FFMC) aims to strengthen this idea. By

Melly Pandher & Aimee McCutcheon, DEPI The program, managed by Department of Environment and Primary Industries (DEPI), with assistance from Rural Finance provides a grant of up to $50,000 to encourage cooperation between food and fibre producers and associated value chain members to form marketing cooperatives or other collaborative structures. In the current economic and business environment it is becoming more difficult for primary producers to survive. Very few individual producers have the diverse range of skills and scale to have commercial business success in these times, when the Australian dollar is high and our competitors have lower costs of production. These days producers can’t be successful by being good producers only, they have to be innovators, researchers, networkers, marketers and collaborators at the same time. The aim of this program is to encourage Victorian primary producers and associated value chain members to form cooperatives or collaborative structures to improve their collective capability to access markets and customers for their agricultural products. Helping them to derive greater efficiencies and marketing advantage, including bargaining power when dealing with large corporations, collective ability to supply critical mass and large volumes of product to meet marketer’s requirements, rationalise facilities, reduce overhead costs and access discounted supplies by purchasing in bulk. The grant is available to eligible groups on a 50:50 cost-share basis, with the remaining cash funds to be provided by the cooperative body. The maximum assistance for each eligible activity is $15,000 with the condition that total assistance provided per cooperative venture will not exceed $50,000. Financial assistance may be available for a range of approved activities such as:

14

Business plans and feasibility studies: Developing business plans and/or feasibility studies for forming a cooperative or collaborative structure. Legal costs: Costs such as incorporation documentation, formal agreements that underpin the establishment of cooperative group such as constitution, shareholder agreements between partnering businesses, memorandum of understanding with supply chain partners /agents Technical advice: Technical advice such as business health checks, systems development, technical advice on markets and products, laboratory testing, supply chain mapping etc.. It may also include advice on intellectual property such as brands, trademarks, databases and customer information, capability and asset audits, financial planning and management etc. Market research and intelligence: Market research and intelligence related activities such as development of market plans and strategies, selecting downstream market partners (processors, agents, wholesalers, etc.) market surveys, data collection, attendance at trade shows and marketing events. Capability development and training costs: Capability development such as training of members and/or staff in business management, corporate governance, marketing principles and export procedures and practice; acquisition of suitable computer software, development of systems (e.g. in quality or production); preparing for and achieving third party accreditation in food safety, export, organic etc.; formation of an expert advisory group or board to support the new venture. To be eligible for assistance under the program, the cooperative group and individual applicants must satisfy the following criteria: 1. The minimum number of members of an applicant group is five, of which at least three members must be primary producers, other members can be in an associated value chain business.

2. Primary producer members must be commercial in scale, turnover and profitability with estimated value of agricultural output in excess of $100,000 per annum each as a guide and derive at least 51% of their incomes from farming activities. 3. Applicants must be new, not yet incorporated or recently established cooperative marketing entities, incorporated less than four years. Entities that are assessed to be financially self-sustaining may be excluded from support. 4. Applicants must be prepared and able to cooperate and must form a shared vision for their proposed cooperative venture. 5. A ‘lead applicant’ or principal contact must be nominated in the application who can demonstrate satisfactory commercial performance in the past. 6. Eligible groups may be cooperative or companies. They will have a marketing focus and be fully commercial in size. A number of factors contribute to the success of a cooperative or collaborative venture including: • • • • •

The Right Philosophy The Right Systems The Essentials (e.g. QA systems) Aspirations (e.g. brand recognition) Bonus Points (e.g. shared infrastructure)

But the most important factor for success of any cooperative venture is honesty, trust and resolve of members to cooperate for success.

August 2013

Landcare Regional Overview Well, what a difference a rain makes! Since our last Landcare Links things have turned around somewhat and we have gone from a position that was looking a bit dire to one that is now looking a little more positive. With the rain largely holding off from our traditional April break, most farmers still backed their instincts and started sowing dry. It looks as though the gamble has paid off and the Mallee is once again starting to green up and look fantastic. Now, as long as the precipitation continues to fall, particularly in that September-October period, we can at least look forward to the prospects of having an average year (whatever that is these days). Landcare in the Mallee is continuing to motor along with all the Facilitators now well and truly embedded into their roles after completing their first full year of activities. These positions are funded until June 2015 so we are now half way through the government program’s original project timeline of 2011-15. The priority directive for these Facilitators is to have established by June 2015, a network of fully self-funded and self-facilitated/ coordinated Landcare groups across the Mallee region. This process has now commenced with projects like pest plant and animal programs that were once addressed by each Landcare group in their own region now being combined for funding purposes and are targeting large-scale funding allocations. These large on-ground works programs are referred to as Landscape scale projects and are highly valued and supported by both federal and state governments, and are therefore more inclined to be funded. Achieving the target of having self-sufficient Landcare groups is going to require a high level of support from the community. This can only be realised if people are willing

to maintain group membership, including executive positions; and support the current consortium arrangements. Strong consortiums have the ability to engage and retain dedicated personnel who are then in the position to drive the wheels of their local Landcare groups. All funding programs have a margin that is available for ‘project management’ which varies from 10-15% of total funding applied for, depending on the grant. By combining project management funding across multiple funding streams it is possible to have sufficient funds available to directly employ someone to implement those projects, while at the same time applying for further funding for future community projects; and hence you start the ball rolling towards becoming self-sustaining. The challenge that all community’s face here is having enough physical, on-ground projects that can attract sufficient funds. To be able to employ someone on a fulltime basis and provide them with the basic operating requirements such as an office, car, phone, computer, etc, can cost in excess of $100,000 plus per annum. Therefore, to provide this level of funding you need to have at least $1,000,000 worth of projects happening in any given year, which sounds almost impossible but in actual fact is not. This is where a consortium/network approach can make the difference. By working together and combining projects, the target of having someone to do all the hard work is achievable. Groups can still apply for their own funding on their own patch they just need to ensure that they allocate that project management monies to a combined ‘project management account’ that is managed by representatives of all the groups involved i.e. a consortium executive. Take this one step further and I would like to put it out to all local communities to

by Kevin Chaplin start to think laterally and look to engage all your local volunteer organisations, not just Landcare groups and bring these community-based organisations together and apply the same logic to all your community projects. In doing so I believe that it would be possible to create a situation where you have at your disposal, a full or part-time funded local community coordinator, who’s role it would be was to identify community projects, apply for funding, run those projects successfully and complete all the reporting requirements. The list of groups that could be involved is endless. Groups such as historical societies, CWA, CFA, sporting groups, progress associations, Landcare groups, friends of groups, 4WD groups, Kindergartens, School groups, Cubs, Scouts, tiddly winks associations……….how long is a piece of string!!!! All it takes is a few committed people and a bit of your time (which you already do when you are involved in any of these organisations anyway) and you have a solution to what seems an insurmountable problem. Someone who can take care of all the red tape, make sure that things happen, and get people organised. You also create employment within your region, which is something we all want to see more of so as our communities can remain vibrant and active for many, many years to come.

Landcare and Sustainable Farming in the Mallee

by Kevin Chaplin only on the sustainability of agricultural production, but also the sustainability and protection of the remaining local native flora and fauna and the general wellbeing of their communities. Landcare and sustainable farming have been intrinsically linked in the Victorian Mallee since Landcare’s inception in the 1980’s and it is through this strong association that a massive change has now occurred in the way that Mallee soils are farmed. The days of the blinding “Mallee Duststorm” have now but almost gone and in the early days Landcare was the conduit for this major ‘farmer-led’ force for change.

South-Western Mallee News

by Daniel Huttig

Welcome once again to the SouthWestern Mallee Landcare page. We are more than halfway through the year now and a lot of activity has been undertaken in regards to pest animal control. Close to $80,000 has been spent on 1080 poison carrot campaigns across the network, and the same again has been spent on roadside ripping programs. This was achieved through financial contributions from the ‘Caring for our Country’ Community Action grant scheme, Mallee Catchment Management Authority (CMA), and Yarriambiack Shire Council. In total, over 6 tonnes of poisoned carrots were laid by over 60 landholders. The decrease in the rabbit population was almost immediately evident and many deceased foxes were also reported. Not content with this, the Landcare groups promptly turned their attention to their roadside ripping campaigns. Favourable conditions saw works completed quickly, and again, with good success. The Woomelang Lascelles group further added to these achievements by forming a partnership with the football club, and erecting a rabbit proof fence around the perimeter of the Woomelang Recreation Reserve.

Stubble Management â&#x20AC;&#x201C; A Guide for Mallee Farmers Mallee Sustainable Farming A Stubble Assessment Guide for the low rainfall cropping areas in the Mallee tri-state area of NSW, Victoria and South Australia has been developed as part of a project which aims to improve soil health and reduce wind erosion using stubble management.

Contact details

For a copy of the Stubble Management guide contact MSF T: 03 5021 9100 W: www.msfp.org.au

By

Steph Haw, MSF Stubble management is a key part of sustainable farming systems and can be used by Mallee farmers to improve the profitability and sustainability of their farms. Reduced soil erosion and improved soil structure are just a couple of the many benefits of stubble retention. Other benefits such as moisture conservation, provision of nutrients, improved biological activity and providing a useful feed source for livestock have also been identified through both research and farmer observations on-farm. The Stubble Assessment Guide has been well received by those who have seen it so far and has been designed to assist farmers to accurately assess stubble cover levels over the critical December to June period. It provides information on stubble management practices to ensure adequate levels of stubble are maintained to minimise erosion and harness the many benefits of stubble retention.

Community workshop has input into the Regional Catchment Strategy.

Have a say in the management of the Mallee landscapes The Mallee Regional Catchment Strategy 2013-19 provides an important tool for community-based groups and local government alike. By

Michelle Kelly, Mallee CMA Reflecting the aspirations of the Victorian Mallee’s communities for the future management of the region’s natural, productive and cultural landscapes, the role of the Mallee Regional Catchment Strategy (RCS) is to guide the development of strategies and plans across the Mallee’s nine Regional Asset Classes: • Rivers • Wetlands • Threatened Species and Communities • Terrestrial Habitat • Soils • Agricultural Land • Culture and Heritage • Groundwater • Community Capacity for NRM

24

Based on the vision of: ‘Informed and active communities balancing the use of resources to generate wealth, with the protection and enhancement of our natural and cultural landscapes’, the RCS aims to maintain and enhance long-term land productivity, while also conserving the environment. Setting regional priorities, the Strategy is also referenced to community, industry, regional, state and federal priorities and policies.

Funding opportunities for communitybased organisations

State and federal government funding agencies have indicated they will be looking to the RCS to help prioritise investment in natural resource management (NRM).

Community and industry groups are encouraged to utilise and refer to the RCS for project planning and funding applications as the Mallee community’s views have helped set long-term (20 year) objectives, and the strategic actions required to achieve the aims of the RCS for the region.

Regional information library

To further assist in project planning and funding applications by individuals, organisations and agencies on private and public land across the Mallee, a dedicated Mallee RCS website has been established. The RCS website: rcs.malleecma.vic.gov.au is the region’s information repository and contains an extensive array of information that continues to grow, including: • Maps – including vegetation, threats (salinised land, depth to groundwater, rabbit and erosion susceptibility), soil type, threatened species, land form and tenure;

• Information on community and industry groups – to assist in identifying potential partners for projects; • Regional Asset information – Rivers, Wetlands, Threatened Species, Terrestrial Habitat, Soils, Agricultural Land, Groundwater, Culture & Heritage, and Community Capacity. In addition, a range of fact sheets and information papers are available.

Your ongoing input to landscape management

Individual, community and industry groups are encouraged to continue to nominate Local Assets for their economic, social, cultural and environmental values throughout the life of the RCS (2013-19). To nominate just go to the Local Assets section under the Development tab on the RCS website (rcs.malleecma.vic.gov.au). Nomination provides opportunities for linkages to projects and information for the whole community. We also encourage you to add to the information that is provided by others to already nominated Assets.

Once the information is uploaded by the Mallee CMA it can be accessed via an interactive map.

communities, industry, key stakeholders, and partner agencies from across the Victorian Mallee.

How to get your copy of the RCS

All sectors of the community are vital to the success of the Regional Catchment Strategy through a sustained and collaborative approach.

Downloadable PDF of the RCS is available on the RCS website at: rcs.malleecma.vic.gov.au or the Mallee CMA website at: www.malleecma.vic.gov.au A hardcopy is also available for viewing at the Mallee CMA office during business hours. The Victorian government gazetted the Mallee Regional Catchment Strategy in May 2013.

Pelicans at Hattah Lakes.

The importance of Mallee waterways Rivers, creeks, lakes and wetlands are the lifeblood of many towns and communities. Their condition is important to production, social and recreational activities, and the environment. By

Michelle Kelly, Mallee CMA Waterways underpin the well-being and productivity of individuals, communities and regional economies by providing water for dryland and irrigated agriculture production (including apiary), recreational activities, and town water supplies. The Mallee’s rivers, creeks, billabongs and anabranches extend from the southern bank of the Murray River to the southern Mallee’s north-flowing ephemeral creeks within the Avoca and Wimmera River Basins.

26

The region’s lakes and wetlands are also diverse and include: riverine wetlands; groundwater-fed natural saline wetlands (e.g. the Pink Lakes); shallow depressions filled by local catchment runoff and a number of artificially maintained wetlands like Kings Billabong.

Good waterway condition

Knowledge about the factors that contribute to the health of waterways continues to improve. This includes: • The influence of the catchments on waterway condition; • Natural climate variability; • Physical/ecological processes such as sediment transport, erosion, and

nutrient dynamics; • The role of connectivity; • Patterns of species diversity and habitat requirements; and • Appropriate water regimes. Declining environmental condition in waterways can have significant costs for regional economies. Algal blooms impact on access for stock and domestic supply, increasing salinity can impact on irrigated crop types, and erosion and bank instability can lead to the loss of valuable agricultural land and public infrastructure such as roads and bridges. Additionally, the costs associated with the control of invasive species such as rabbits, weeds and carp is expensive and time consuming.

Integrated management

Communities, landholders, Landcare networks, industry and community groups are playing an active role in

improving the environmental condition of the Mallee’s waterways. The Mallee Regional Waterway Strategy 2014-2022 (currently being developed) will provide a framework over an eight-year period for the integrated management of rivers, creeks, lakes and wetlands in the Mallee; reflecting the communities plans for waterway management and guiding investment into the future. The development of a single, regional planning document for all waterways brings with it a number of benefits including more effective and efficient management through the establishment of specific actions. Part of an integrated management framework, the Mallee Regional Waterway Strategy (RWS) will recognise that the task of managing waterways cannot be conducted in isolation from the broader management of catchments and land. Therefore, the RWS will take into account other plans, such as Regional Growth Strategy, municipal plans, National Parks Plans, Public and Private Fire Protection Plans, and other longer-term strategies such as the Flood Management Strategies and council planning overlays.

Key features

The Mallee RWS will be an adaptive management framework providing the flexibility to respond to seasonal climatic variation, such as drought, flood and fire, and the potential impacts of climate change. It will provide an eight-year action plan (2014-2022) for managing the region’s waterways by: • Identifying the Mallee rivers, creeks, lakes, and wetlands that have high environmental, social, cultural, and economic values; • Determining which of these waterways are priorities for action to protect the values that are important to the community; • Establishing goals and targets for these priority waterways; and • Identifying the roles and responsibilities of all stakeholders in the implementation of these activities. The Mallee RWS will provide an important tool for guiding management and investment activities for our waterways over an eight-year period by informing all levels of government, key stakeholders and funding partners of the Mallee communities plans for maintaining and enhancing waterway condition.

Where to next?

We need your help to develop the Strategy. We want to know which of the Mallee’s waterways are important to you and why. We also want to hear your suggestions for management activities in and around the Mallee’s waterways. Local knowledge is crucial to providing information about the many economic, social and cultural values that waterways provide. This information will help determine where priority activities should be undertaken over the next eight years. Decisions and management programs will be underpinned by the information provided by people throughout the Mallee and the best available science and knowledge. A questionnaire is included with this edition of the Mallee Farmer. Please assist us to develop the Mallee RWS by completing the questionnaire and returning it to the Mallee CMA office by Friday 23rd August 2013. Alternatively, a more detailed questionnaire is available on the Mallee CMA website: www.malleecma.vic.gov.au

Piangil field plot trial site

Risk reduction options for canola establishment in dry years Replicated field plot trials were set up at Walpeup and near Piangil in the Victorian Mallee in 2012 to determine the impact of 12 agronomic treatments on canola establishment and production. By

Ivan Mock, Dodgshun Medlin Agricultural Management Both sites had sandy soils and growing season rainfalls were 44% and 55% of the long term averages for each site. This was an ideal scenario to investigate options that reduce risks to soils and profitability by poor canola establishment in dry years. Canola is now a significant crop in the Mallee, providing diversification from cereals and is a high value grain. However, poor crop establishment occurred with approximately 20% of canola crops sown in 2011 and 2012. Areas of crop that fail to establish satisfactorily have reduced potential yields and profitability and expose the bare soil to additional risks of wind erosion and weed infestation. Caring for our Country funding was allocated to Dodgshun Medlin to explore the canola

28

establishment problems and develop agronomic strategies to mitigate the associated risks.

Scoping surveys

An extensive survey of 42 Mallee growers with over 25,000ha of canola in 2011 determined that 20% of canola did not establish successfully causing additional costs and lost production totalling $1.4m. This survey and monitoring commercial crops in 2012 identified light sands and clay as soils most prone to establishment problems as they had less available crop water in dry seasons. Ground cover of monitored crops one month after emergence ranged from 77% with good establishment, 17% with medium establishment and 8% for poor establishment. Stubble remaining at sowing was also identified for its potential to compromise sowing depth and later sown crops were thought to have more establishment problems.

Field frials

Two field trials were established in 2012 at Walpeup and Piangil to assess landholdersâ&#x20AC;&#x2122; belief that agronomic options such as sowing depth, sowing rate and timing were key factors in canola establishment. The aim of the field trials was to validate the impact key factors have on establishment and to evaluate improvements achieved by alternative management practices. The replicated plot trials contained 12 treatments that were combination of the following management practices: Time of sowing: Early - close to break rains Late - delayed 2 or more weeks (as if when waiting for additional rain) Seeding rate of 43C80 canola: Light - 1.5 kg/ha Medium - 2.5 kg/ha Heavy - 3.5 kg/ha Seeding depth: Shallow - 1-2 cm Deep - 3-4 cm Number of canola plants established and the ground cover they provided (number x plant size) for each treatment is shown in for Walpeup in Table 1.


The

Mallee Farmer The maximum canola yield at both sites was the early, shallow sown high seeding rate treatment (0.8 t/ha at Piangil and 0.5 t/ha at Walpeup). The difference in yields reflected the relative rainfall at each site. Table 2 contains the yields for each treatment expressed as a percentage of the maximum yield and is the average for both sites.

Conclusions

Results were obtained over the 2011 and 2012 cropping seasons when canola establishment problems were widespread. Both seasons had little rainfall over the normal canola sowing period from April to May. Conclusions on factors contributing to poor establishment and agronomic management to mitigate them are therefore most applicable to these conditions when problems to canola establishment are accentuated. (a) Establishment problems were worst on sand and clay textured soils. Sands which store little water from the months preceding sowing and clays, which require higher water content before it is available to germinate the canola seed, were most frequently associated with poor establishment in dry starts. These soils occur most frequently on dunes or swales while intermediate soil textures on the mid-slopes were less prone to poor canola establishment. (b) Early sowing reduces the risk of wind erosion with poor establishment. Early sowing in dry starts was not associated with rapid crop establishment or greater density but those plants that did establish were larger than those sown later and generally provided 5-10 times more ground cover to protect the soil early in the season. Adequate ground cover to reduce the risk of wind erosion was therefore achieved earlier in the season although this was often still two or more months after sowing. (c) Increased seeding rates accelerated ground cover. More plants established when the seeding rate was increased although this was not always significant. When sowing was delayed until soil water improved there was generally no need to use high seeding rates to achieve satisfactory canola plant densities. (d) Sowing shallow may be better on dry soils and with light rainfall. It required less rainfall to increase moisture in the surface 1-2cm to achieve germination than it did at 3+ cm. Conversely soils close to the surface dry out quicker than those deeper in the

profile unless follow-up rainfall occurs. Sowing depth had no significant impact on establishment if sowing was delayed to coincide with heavier rainfall events.

Recommendations

1. Maintain stubble or trash cover on the soil surface to reduce the risk of wind erosion until crops establish. This is particularly important with canola which is often dry sown before there are clear indications that there will be a good seasonal break to ensure timely crop emergence.

2. Light sandy and heavier clay soils have the worst emergence problems in dry seasons so consider if there are better options than canola on these soils when a poor start to the season is predicted and particularly if ground cover before sowing is less than 50%. 3. Sow early if the decision has been made to sow canola, possibly due to weed or disease problems in the paddock. Early sowing reduces the risk of erosion before crop ground cover develops. Also, Mallee canola yields will be low in dry seasons but far worse if sowing is delayed.

Many people took advantage of Saturday to experience the Field Days for the first time.

Mildura Field Days Farming Futures Program Blue skies and sunshine were certainly a pleasing forecast for the new look 2013 Mildura Field Days. By

Kim Trigg, Mildura Field Day Committee Secretary The committee was slightly anxious about the weather in the days leading up to the event, however, there were many contingencies built into the program and with exhibitors and sponsors opting for some larger undercover exhibits, this year’s event was always looking to bigger and better things. The greatly increased number of exhibitors this year reflects the diversity of interest that our farming community and the committee was aware that there is increasing interest for leisure and hobby displays which supports a better

work - life balance for farmers. New concepts included a partnership with the Sunraysia Farmers Market which proved to be a huge success. Comments received from other food vendors mentioned their sales were not impacted so we believe it offered a win:win for all, presenting a true “paddock to plate” experience. Attendance numbers were well up on previous years and many commented that they needed an extra day to get around it all, which is a great start to re-invigorating this important event. An example of another highly popular exhibit was the Mallee Catchment Management Authority’s (CMA) interactive reptile display that our attendee’s couldn’t get enough of. The display allowed people to get up close and even touch live lizards and goanna’s to assist in the promotion of the newly launched Mallee Lizard Field Guide. The guide aims to build awareness of local species and

habitat requirements ensuring we keep our local lizards safe and sound. The environmental theme was further supported with the “Green Days” marquee this year. It was really great to see the number (about 350) of people come into the marque to take a look at the various environmental displays including the Mallee and Murray CMA’s, Buronga Inland Botanical Gardens and the National Parks crew from Mungo National Park, to name just a few. Spanning more than sixty years, the Mildura Field Days has traditionally had a dried fruit focus, while also being the lure for locally invented farm “gadgets”. The promotion of innovation has seen the event well attended over the years by people from a range of industries and promotion of innovation is something that will continue to be supported into the future. The innovation theme was reinforced with the Earth Systems mobile biomass

pyrolysis technology demonstrating the conversion of grape vine and citrus waste to biochar. Biochar is a form of charcoal produced from burning organic materials in a specially designed oven that operates at high temperatures with restricted oxygen the resultant material produced is a type of charcoal that is thought to have benefits to soil quality and even under some circumstances increased crop yields. It is also thought that there may be potential carbon credits through increasing the carbon content of soils. There is research occurring in Australia and overseas and some of this is demonstrating that biochar may support the better retention of soil nutrients, provides a good environment for soil microbes, improves soil structure and

and especially families and towns folk experiencing the field days first hand, many saying for the first time.

The committee had to make some tough decisions this year and the Friday/ Saturday concept was introduced to see if this could expand the events messages of a “Sunraysia Food Bowl” exposè and “Where Agriculture and Community Unite”. Mildura Field Days should be an event that supports the promotion of sustainable food production, environment and community awareness; and together with the exposure of our expansive produce, manufactured products and services to outside networks it has the potential to improve our local economy.

With the assistance from the Mildura Branch of the Australian Dried Fruits Association, the Mildura Field Day Committee has been successful in receiving $55,000 through the Caring for our Country Community Landcare Grants Program and we will be looking forward to the further opportunities this will bring to the event.

The decision to open on Saturday certainly paid off with many local people

No-till farming benefits the sandy loam soils of the Mallee from erosion.

No-till farming sees Mallee farm size double in a decade Terry Kiley, one of nine sons of Mallee soldier settler Rex, was always going to be involved in farming. By

Melissa Pouliot, for the Victorian No-Till Farmers Association While at boarding school in Sunbury he was more interested in the academic side of farming than the practical side and had very little interest in cropping. Terry spent his early working life in shearing sheds around the district and further afield and for around 20 years sheep were his bread and butter. He

32

finds it ironic that he is now farming their family farm ‘Kiley’s Run’, between Speed and Sea Lake, and there are no sheep, just crops. Almost nine thousand hectares of them. That’s over 21,000 acres on the old scale. Terry is also one of the trailblazers, although he would never describe himself as such, for minimum till farming – a farming system that has changed the face of Mallee farming during the past decade. Married to Vonda, Terry was one of the first Mallee farmers to join the Victorian No-Till Farming Association, move away from conventional farming and start practicing minimum till techniques. A decade later, 95 per cent of Mallee farmers are following suit. A testament to the system is a no-till event that Terry hosted on their farm in March this year. Dodgshun Medlin

organised the event, supported by Vic No-Till and the Grains Research and Development Corporation, which saw almost 300 farmers converge on one of Kiley’s Run’s sandy loam paddocks. Guests witnessed an active seeding demonstration by nine modified tyne, dedicated tyne and disc seeding machines while celebrating 10 years of minimum till in the Mallee. Minimum till is ‘one pass seeding’ with points, creating less than 20% soil disturbance. Zero or no-till is ‘one pass’ sowing system using discs for minimal soil disturbance. For Terry, the move to minimum till has enabled him to almost double his acreage in the past decade. “Due to severe erosion caused by wind and stock, I knew conventional farming methods were just unsustainable. If we hadn’t changed I’m sure we wouldn’t


The

Mallee Farmer have been able to expand. Reducing erosion has been a huge benefit, especially up here with our sandy loam soils. Overall our farming operation is a lot more efficient. And along with the other 95 per cent of Mallee farmers, we’re reaping the benefits.” Terry said a presentation by Vic No-Till founding president Rob Ruwoldt from Minyip in 2002, a field day on local agronomist Danny Conlan’s Nandaly farm and a visit to South Australia’s Eyre Peninsula all led to the same conclusion. “What we were seeing with No-Till farming systems was very impressive. After a particularly bad year for wind erosion in 2002, which was also a drought year, we knew we couldn’t keep farming that way, it was a no brainer. So in 2003 we adopted minimum till.” Terry remained a Vic No-Till committee member for seven years and is still part of the association’s 500-plus state-wide farming network. He said being part of the association helped broaden his scope and boost his confidence when changing his farming system. Terry believes he would’ve changed sooner but technology and agronomy support were unavailable to back him up. “I wanted to adopt no tillage, direct drill methods in the 1990s but there was no agronomy backup in this area. All the local dealers were just selling chemicals. Terry says it wasn’t until Danny Conlan came home to his Nandaly farm after working as an agronomist in Victoria’s northeast and the Southern Riverina, that Mallee farmers had the necessary backup to further explore no-till farming. “Not only did Danny have the agronomy background, he was practicing no till techniques on his own farm. “In that first year we converted a flexicoil air seeder to knife points and press wheels. The local John Deere dealer also gave us a Starfire 2, 10-centimetre guidance system to trial. I’d never even heard of this technology until then. We cropped around 5000 hectares and had a really good year. That set us up. If you’re expanding your cropping hectares it’s critical to have a good year. The following year was fairly dry but we had another good year.” Terry says it was the combination of seeing it work on-farm, agronomy support, the growing network through the Vic No-Till association plus improvements in farming equipment that helped make it happen. He also regularly travels across Australia and overseas to get a global picture of farming. He’s travelled with farming groups to countries

including South America, Canada, Vietnam, Denmark and Sweden. It’s all part of his ongoing search for knowledge to improve efficiency and sustainability on his own farm that he now works with son Zane and son-in-law Mick Ellis, who’s married to daughter Brianna. At the moment, the family is working towards a four-year rotation of legumes, canola, wheat and barley. “We’re constantly adapting and making changes to improve sustainability and profitability. We are starting to see a few issues with resistance to rye grass and radish so it’s important we stay on top of and address these things all the time.” Terry says that as well as enabling them to expand, minimum till has simplified their farming operation.

“It’s quite amazing how far we’ve come in 10 years. It’s been a remarkable change in the Mallee and we are getting better yields. No-Till farming is all about being efficient and using our machinery more effectively. We wouldn’t be where we are today if we were still using conventional farming methods. Who knows where it will go from here.” In the Wimmera, an estimated 80% of farmers are using minimum or zero/notill techniques. This is a similar number to the minimum or zero-till farmers in Yarrawonga in north-east Victoria.

Aboriginal Burial Site. Inset: Cover of the new field guide.

Pest animal field guide A new field guide is now available to help Mallee farmers and land managers deal with pest animals on sites of cultural significance. By

Ben Parker, Mallee CMA Produced to debunk the myth that an area of cultural heritage on private property must be taken out of production, the field guide is an easy-to-use glove box guide to controlling invasive species such as rabbits, pigs, foxes and goats without damaging cultural sites. Titled “Land management practices to preserve Aboriginal cultural heritage values”, the field guide also has information to help farmers identify Aboriginal cultural places and learn more about the preferred control methods for pest animals on each type of cultural site. Mallee Catchment Management Authority (CMA) coordinated the

34

development of the field guide by working in partnership with members of the authority’s Aboriginal Reference Group, Indigenous stakeholders across the region, and partner agencies. “This project has succeeded in directly involving Indigenous stakeholders in natural resource management, while also preserving vital indigenous ecological knowledge and building strong working relationships,” said Mallee CMA board chairperson Sharyon Peart. “ To ensure the project was conducted in a culturally appropriate and sensitive way, the Mallee CMA formed an Aboriginal Reference Group to act as a steering committee for the project and a number of in-field workshops were undertaken to ground-truth pest management methods.”

Ms Peart said the field guide was particularly relevant to the local region, with more than 8000 registered sites of Aboriginal significance recorded in the area. “The booklet has been designed with clear images to show you what cultural sites can look like, as well as easy-toread descriptions and pointers on what to look for, this guide is very practical.” The field guide was produced by the Mallee Catchment Management Authority (CMA), through funding from the Australian Government’s Caring for our Country.

Spencer’s Goanna with the Mallee Lizards Field Guide (NB: not a lizard of the Mallee)

Mallee Lizards Field Guide now available A new field guide on Mallee lizards has been developed by the Mallee Catchment Management Authority (CMA) and is now available free of charge. By

Rachael Slorach, Mallee CMA More lizard species are found in the Mallee than anywhere else in Victoria, with many of these considered threatened. The field guide includes 48 lizard species, including geckos, legless lizards, skinks, dragons and goannas. “This field guide has wonderful photographs of the lizards found in the Victorian Mallee, with simple descriptions and interesting facts,” Mallee CMA Board Chair Sharyon Peart said. “It will be a useful tool for individuals, schools and groups to identify lizards when they are out and about in their local environment.”

36

The Mallee Lizard Field Guide is part of a series developed by the Mallee CMA to showcase different groups of fauna within the region. Other field guides include Mallee waterbirds and Mallee frogs. To launch the Mallee lizards field guide, the Mallee CMA organised a live lizard display at the Mildura Field Days, which gave people the chance to get up close and personal with a range of lizards from the Mallee and beyond.

What are lizards?

Lizards are scaled reptiles (Class Reptilia – Order Squamata). Typically lizards are oviparous, that is they reproduce by laying eggs in nests. Some species however, have other ways of reproducing such as the Blue-tongued and Stumpy-tailed Lizards that give birth to live young.

Where do lizards live?

Lizards in the Mallee occupy a wide range of habitats, from semiarid environments to those close to waterways. Many depend on the specialised habitat in which they live; others are more adaptable and can live almost anywhere, including farming and urban environments. Some lizards dig their own burrows for shelter, others shelter in soil cracks, logs and branches, tree bark, rock crevices, vegetation such as spinifex, or abandoned spider burrows.

What are the main threats to lizards? Habitat depletion and degradation are the two main threats to lizard populations.

Approximately 53 percent of vegetation in the Mallee region has been cleared for agriculture, urban development, timber and mining. As a result of this clearing, a number of vegetation communities are now quite severely depleted, fragmented or degraded. These include Buloke Woodlands, Belah Woodlands, Woorinen


The

Mallee Farmer Case Study – Hooded Scaly-foot

The Hooded Scaly-foot is a large, legless lizard that can grow to lengths of up 475mm. The scales on these lizards range from pale grey to reddish-brown, and are arranged to give the appearance of vague lines, or a checkerboard. It has a dark head, rounded snout and prominent ear openings. The Hooded Scaly-foot can be confused with snakes however a significant difference is that they have broad and flat tongues, while snakes have forked tongues. This lizard is found in open vegetation communities on heavy soils, such as Chenopod Shrublands and grasslands, where it shelters in soil cracks and invertebrate burrows. It is most active during the night, and is thought to become inactive during the winter. Females lay a clutch of two eggs once a year, during the summer. When threatened the Hooded Scaly-foot will rear up and flick their fleshy tongue. They will utter a long wheezing squeak if grasped, and will readily discard their tails as a defence mechanism. Mallee, Ridged Plains Mallee, Parilla Mallee and Plains Savannah. Rabbits degrade lizard habitat by intensively grazing the grasses that provide lizards with shelter and protection. Cattle, feral pigs and goats can trample lizard burrows and cause soil compaction and erosion. Burrow disturbance and destruction also occurs as a result of motorbikes and off-track four wheel driving.ich lizards are threatened? Of the lizards that are found in the Mallee, nine are listed as threatened under the Victorian Flora and Fauna Guarantee Act 1988 (FFG Act). These are: • Beaked Gecko (Rhynchoedura sp.) • Mallee Worm-lizard (Aprasia aurita) • Hooded Scaly-foot (Pygopus schraderi) • Heath Skink (Liopholis multiscutata) • Millewa Skink (Hemiergis millewae) • Dwarf Burrowing Skink (Lerista timida) • Samphire Skink (Morethia adelaidensis) • Lined Earless Dragon (Tympanocryptis lineata) • Rosenberg’s Goanna (Varanus rosenbergii)

Case Study – Sand Goanna

The Sand Goanna is a large lizard with a long, vertically compressed tail, and a forked tongue similar to a snake’s. It’s body colour is grey to dark-brown with red, brown, yellow or white blotches that form bands. It can grow up to 1.6 metres long, including its tail.

Above: Hooded Scaly-foot page. Above left: Cover of the Mallee Lizards Field Guide. Below: Sand Goanna.

The Sand Goanna can be found scattered throughout the Mallee region in heathlands and grasslands. They can also be spotted on farmlands and will flee rapidly if approached too closely. Sand Goannas use their strong claws to dig complex tunnels that often extend into the burrows of other animals. Females are known to dig chambers within termite nests to lay their eggs. This lizard actively forages in holes, crevices and logs, feeding on a variety of fauna including snakes, frogs, invertebrates, small mammals, birds and other lizards.

How can I obtain a field guide?

Copies of the Mallee Lizards Field Guide are available from the Mallee CMA at the Department of Environment and Primary Iindustries (DEPI) Complex on the corner of Eleventh Street and Koorlong Avenue, Irymple, or by contacting the Mallee CMA on 5051 4377.

The Last Word Dispersal

What is worse flood or fire?

The fruit is commonly eaten by foxes and birds. Birds are the main method of spread. It’s the reason so many are found under power lines, at the base of other trees, and along fence lines, where birds sit. The mature plants can also sucker from roots when disturbed.

It’s strange how some memories just refuse to disappear or even diminish over time. I vividly remember, then aged six, the flood that followed when Arthurs Creek broke its banks, inundating our three acre market garden and piggery. It was quite a sight watching Dad and Uncle Bill wrestle the sows to safety. But what really stuck in my mind was Dad and Uncle Bill talking afterward. Uncle Bill asked Dad, “What’s worse, flood or fire?” Dad said without hesitation; “Flood; It will take years to reclaim the market garden, not to mention the two miles of road washed away, along with half the fencing. The pumpkins and tomatoes, have had it, nothing left but a mess of rotten vegetables and mud, which is now on the other side of the creek; and the bridge is gone as well. “At least you have half a chance to fight a fire, and it mostly cleans up after itself,” he said. So what is the point of my flood memoir? Well it’s the aftermath of our big wet and floods of 2010 and 2011, which caused so much destruction. What Dad was saying is that the effects of flood can dramatically change the landscape and hang around for a long time. We are still seeing the legacy of the big wet today, and there is no better example of this than the resurgence in some of our worst weeds, including our old mate the African Boxthorn (Lycium ferocissimum).

Mallee’s Most Wanted

Our second in the series of the Mallee’s Most Wanted, takes at a look at a very tough critter indeed, which has the potential to spread like honey on a hot crumpet under the right circumstances. First introduced into Australia in the 1800’s, the African Boxthorn was thought to

be a hardy plant capable of quickly establishing hedges to contain stock. It was massively successful, stock hate going anywhere near it. So why is it a problem? In a nut shell, it spreads quickly, forms impenetrable stands, drought tolerant, and provides excellent harbour for pests such as feral cats, foxes, rabbits, and fruit fly. Once established, this plant is hard to deal with. It is a Weed of National Significance (WoNS) and in the Victorian Mallee is classified as a regionally controlled noxious weed, meaning that it is the responsibility of the land manager to deal with. Boxthorn, a perennial shrub, generally reaches two or three metres in height. Its woody, dense, thorny growth consists of rigid multiple branched stems. The main stems have spines up to 15cm long. The succulent vivid light green leaves stick out like bald bandicoots in a burnt paddock during periods of rapid growth, like now. Drought resistant, they can completely shed their leaves, but rapidly bounce back after rain. Fruit set generally occurs in autumn but given the right conditions can happen at any time. The ripe orange-red globe-shaped berries are five to 10mm in diameter, contain 35 to 70 seeds.

Effective, long-term control will require the integration of a number of techniques. Physical removal is best done with tractor and blade or similar. Chemical control on young vigorous growing plants with herbicides is an option; only use a registered herbicide according to the directions. Large plants can be treated using a cut stump treatment (a pole saw is recommended). Basic common sense principles apply, get into them while small and time your control methods for maximum effect.
