GLANBIA IRELAND AGRONOMY UPDATE

Introduction Spring 2022 has arrived and unfortunately the threat of war in Eastern Europe has become a reality. Tillage farmers are well aware of the situation in Ukraine but the full repercussions of the associated political decisions are not fully known. Gas and fertiliser availability have been centre stage before the war commenced, but the supply situation has only been exasperated in recent weeks.

Food security has now become a real issue and the recent setting up of the national fodder and food security committee will no doubt have an impact on the tillage sector in the near future. What exactly the impact of this is will be unknown for some time. The growing and producing of native cereals may become of greater importance in the near future to play their part in feeding the national herd and provide quality grains to the drinks and milling sectors.

With this in mind growers must continue to strive to produce crops in a sustainable manner.

The autumn of 2021 allowed for a decent drilling campaign, resulting in good area of winter cereals for harvest 2022. The majority of crops went into the ground in ideal conditions and have endured the winter in good order creating the potential for good yields come harvest time. Break crops continue to be a vital component of crop rotations, and the area of winter oilseed rape has increased once again. Break crops are a vital component of Integrated Crop Management and provide an ideal entry point for winter cereals.

We now turn our attention to spring cropping, crop protection and agrochemical options available for the season ahead. With promising grain prices for the harvest ahead against a back drop of increased growing costs it has never been more important to maximise crops performance and yield.

As always, the Glanbia Agronomy team are on hand to help growers make informed and conscious decisions this spring and for the year ahead. This technically astute team would be more than happy to discuss all aspects of successful crop production Wishing you all the best for the season ahead.

Precise Application of Fertiliser Written by Jayne Smyth

Steps to precise application of fertilisers Blends and granule sizes 1. Select a fertiliser spreader capable of even spreading at the desired bout width with the fertiliser types to be used.

2. Select fertiliser that has good spreading characteristics with at least 80% of the granules in the 2 - 4 mm size range and preferably smooth round shapes.

3. To ensure an even spread across the bout width, use the spreader manufacturer’s resources such as instruction manuals, internet material or phone apps, to set the spreader accurately for the fertiliser being used. To apply the correct rate of fertiliser, the spreader should be calibrated, using the manufacturer’s resources as a starting point.

Setting the fertiliser spreader

4. Clean after every working day and protect from corrosion.

Check - all the spreading components for wear frequently.

There are two elements to getting fertiliser spread evenly at the correct rate in the field:

Fertiliser Characteristics

• Setting the spreader to spread evenly with a

The physical characteristics of the fertiliser will affect how evenly it spreads and the settings required. The key factors are:

• Calibrating the spreader to spread

• Density of the fertiliser: Low density fertiliser such as urea (80% normal density), is more difficult to throw.

• Size of the granules: Generally larger particles will

throw further. Particle size distributions with the majority of particles (80%) in the 2-4mm range will usually allow a good spread to be achieved, but larger diameters (3 – 4.5mm) will probably make it easier achieve wider spread widths. The component parts of blends should ideally have similar size distributions.

• Shape of the granule: Rounded particles

will roll off the disc more predictably than irregular granules or angular particles.

• Strength / hardness of granule: Strong

particles will resist break-up on the disc.

Some fertilisers are produced as rounded prills. As long as the density of the product is high and the size distribution is correct, prills will spread at least as well as similar sized granular products. The importance of physical quality depends on the bout width being used and the spreader. Generally wider bout widths require better physical quality.

Urea Urea has lower density which presents a greater spreading challenge and it usually will not spread as wide as denser material. Urea has a particle density of 0.7 to 0.8kg/L while other fertilisers such as CAN have a density of 1.0kg/L. Always look for a urea product with larger particle sizes. Even with a good size distribution it is vital that the correct spreader setting is used and that the limitations of the spreader with urea are observed (maximum bout width etc.). Wind will affect urea more than ordinary fertiliser, so spread in calm conditions if possible.

particular fertiliser at a specific bout width. the correct rate of fertiliser.

Setting for even spreading Most modern spreaders need some level of setting or adjustment to enable them to spread different fertilisers at different bout widths. The elements that may be set depending on the machine design include:

• • • •

Disc type and speed.

Vane type and position u Fertiliser drop point on the disc.

Height above crop.

Spreader angle e.g. tilting discs upwards at back to throw further.

The setting needed is machine specific and is based on the type of fertiliser being spread and the bout width chosen.

Basic information is given in the instruction manual, but increasingly either spreader manufacturer websites or phone apps are used to allow the operator easily access up-to-date setting information. Typically the operator is asked to identify the fertiliser being used by brand name or, by determining its size distribution (simple sieve box test), granule strength (simple pen-type tester), density (urea or not) and granule shape. The desired bout width is also entered in the app or web page. From this information an appropriate spread chart is selected and the spread element settings (discs, vanes, drop point etc.) are given. Usually a rate setting guide is also given once the desired rate in kg/ha is entered.

Calibration of fertiliser spreader Calibration of fertiliser spreaders is essential for accurate application rate of fertiliser. Fertiliser application rate is affected by: BOUT WIDTH Bout width is the distance from the centre of one tractor pass to the centre of the previous tractor pass. Spreaders can be set for different bout widths; the bout width is a key element for application rate setting. The accurate application of fertiliser over the working width depends on how accurate the bouts are. With cereals, tramlines ensure constant bout widths. On bare soil or on grassland, either the bouts must be marked temporarily or a GPS guidance system should be used. Trying to estimate bout widths of more than 10m by sight is risking accuracy.

FORWARD SPEED It is essential to have an accurate forward speed measurement, whether your tractor gives a direct speed reading or its read from a chart in conjunction with a tachometer (rev counter). The tractor’s speed measurement should be calibrated as tyre sizes and other factors will impact on accuracy. This is carried out by measuring a precise distance (e.g. 100m) and timing the tractor as it passes the start and finish of that distance. For example if it took 50 seconds, then its speed is 2m/s or 7.2 km/h (m/s x 3.6 = km/h). Various GPS based devices can give a forward speed measurement. Similarly an accurate indication of pto speed is essential to allow the spreader to be operated effectively.

Preparing the tractor and fertiliser spreader for work Before spreading the tractor and spreader should be checked and set-up according to the manufacturer’s instructions. While this will vary from machine to machine the following should be checked:

• Tractor forward speed and pto speed indicators working

or tachometer working with speed chart. Adequate front ballast for stability.

• Spreader attached securely to tractor; level from side to

side and centred (link arm stabilisers); top link in correct position to minimise spreader angle changes and correct length for required spreader angle.

• Lift controls set to allow correct disc height (as

determined by the manufacturer) from crop or ground.

• PTO guard intact and secure and all other guards in place, check vanes, discs, agitators and shutters/outlets for wear.

• Lubricate as per instruction manual.

REGULATOR SETTING Regulator setting of the shutter controls the amount of fertiliser leaving the hopper to the discs or spout. The wider the shutter opening, the higher the application rate will be.

CALIBRATION PROCEDURES Fertiliser flows at different rates depending on humidity, granule shape and size. The machine handbook, mobile phone applications, and fertiliser databases on the internet from manufactures give approximate guides to operators for regulator settings. Calibration of different spreader makes and models will vary. The spreader manufacturer’s instructions should be followed in all cases.

Galaxy

0.65 - 1.0 L/ha

COMMENTS (Zypar = Boxer + Arylex mix) (Presite Max = Harmony Max) An excellent mix which will take almost all weeds. Rate depends on weed pressure at time of application. Very good on Vol beans. Can be mixed with Wild Oat herbicide, aphicide and T1 fungicide. This mix will take all weeds that Cameo Max will take.

(Pixxaro = Hurler + Arylex mix) An excellent mix. Very good on Cleavers, Fumitory and Chickweed. The 2 Litre pack size and application rate may suit field sizes. Can be mixed with Wild Oat herbicide, aphicide and T1 fungicide.

(Galaxy = Boxer + Hurler + Clopyralid mix) This mix is more suited to Wexford or where resistant Corn Marigold is an issue. Rates depend on weed pressure at time of application.

Max individual dose of Galaxy = 1.0 L/ha. For resistant Corn Marigold, mix with Gartrel @ 0.2 L/ha.

Gartrel @ 0.2 L/ha = 40g/l Clopyralid. Excellent mix and will control Cleavers, Chickweed and Speedwell. Presite Max can be swapped for Cameo Max where Fumitory is an issue.

(Hiatus = Calibre) Hiatus has a very broad weed range. Excellent on Vol Potatoes, Fumitory and Speedwell. Not effective on resistant Corn Marigold. Can be mixed with Wild Oat herbicide, aphicide and T1 fungicide. Do not use Hiatus on Oats.

A good option but weed spectrum narrower than the options above. Cameo Max has the advantage of controlling Fumitory but will not control resistant Corn Marigold and resistant Chickweed. Can be mixed with Wild Oat herbicide, aphicide and T1 fungicide.

GENERAL COMMENTS 1. Herbicide can be included with T1 fungicide, Wild Oat Herbicide and Aphicide. Do not mix Wild Oat herbicides with any CMPP or MCPA type products. Do not mix Wild Oat herbicide with Kinvara.

2. Presite Max can be swapped for Cameo Max and vice versa.

3. Rates should be adjusted depending on weed pressures and conditions.

4. Trace elements can be included at this timing.

5. Delfan Plus or Phylgreen @ 1.0 L/ha – 2.0 L/ha should be considered to help reduce stress and aid recovery of crops.

Oil Seed Rape Canopy Management Written by Jayne Smyth

Green Area Index is the ratio of green leaf and stem area to the area of ground on which the crop is growing. GAI will vary from crop to crop (and within crops) depending on sowing date, available nitrogen and grazing by pigeons. Assessment of the Green Area Index will guide when and how nitrogen should be applied.

The following points should be considered:

• A target canopy cover of GAI 3.5 at the start of flowering to deliver maximum yield this should equate to between 6,000 and 8,000 pods per square metre.

• Nitrogen has a large influence on the canopy size.

• It requires 175 kg/ha N (from a combination of soil N

release, canopy accumulations and applied nitrogen) to achieve GAI 3.5 by flowering.

• Start nitrogen (and sulphur) application on thin/grazed crops as soon as growth commences in spring.

• Hold back 35-60 kg N/ha in all crops to be spread as

near as practically possible to mid-flowering. This is to prolong green-leaf area during pod-fill. Leaves are the most efficient part of the rape plant to convert sunlight into yield.

• For each 0.5 t/ha of yield above 3.5 t/ha up to a maximum of 5 t/ha the crops needs 30 kg/ha of Nitrogen.

• Fungicides with growth regulation properties can be used to manipulate crop growth habit (and control disease) but check GAI before application.

38

GLANBIA IRELAND AGRONOMY UPDATE

GAI = Ground Area Index and is a measure of how much green plant material is in a crop. It can be measured by weight (best suited to wide row spacing’s*) or by digital photograph (best suited to narrow row spacing’s). Download the OSR GAI app from the app store onto your smart phone and it will calculate the GAI from the photograph.

If you don’t have a smart phone you can still measure the GAI by following the steps below. *Measuring GAI with wide row spacing’s.

1. Cut all plants from a meter row.

2. Weigh the fresh weight collected in kilos.

3. Divide the weights by 0.61 (for 24 inch spaced crop) to take into account the row spacing.

4. Multiply the final figure by 0.8 to get the GAI of the OSR crop.

Importance Soil-borne diseases, such as sclerotinia stem rot, clubroot and verticillium wilt (also known as verticillium stem stripe), have increased in recent years, favoured by shorter rotations.

Sclerotinia stem rot is usually the main disease to consider at flowering. The disease often causes little damage but can halve yields when severe. It also poses a threat to other broad-leaved crops in the rotation.

Sclerotinia in Oil Seed Rape Sclerotinia stem rot is usually the main disease to consider during the flowering stages of oilseed rape. Although the infection cycle of Sclerotinia sclerotiorum is complex, a good understanding of the three main risk factors – the presence of sclerotinia inoculum, warm and humid weather conditions and crops in flower – will help you target control.

Symptoms The pathogen that causes sclerotinia (Sclerotinia sclerotiorum) in oilseed rape can also infect other crops, such as potatoes, peas, carrots and many other vegetables. In oilseed rape, when lower main stems are infected, white stem lesions form with black sclerotia within the stem cavity. Infection can cut off the supply of food and water to the canopy. In extreme situations, whole plants can be lost. If infection occurs during later flowering, infection tends to be limited to the lateral branches with a much less damaging effect on yield.

Life cycle Sclerotinia in oilseed rape is caused by the fungal pathogen Sclerotinia sclerotiorum. The infection cycle is complex and requires three main factors: the presence of sclerotinia inoculum, warm and humid weather conditions and crops in flower.

In spring, sclerotinia fungal resting bodies (sclerotia) in the soil germinate. This usually occurs when soils are moist and warm (>10°C). Pale brown fruiting bodies (apothecia) are then produced that release airborne ascospores.

These spores land on oilseed rape petals and stick to other plant surfaces (especially if there is light rain). The spores require external nutrients, derived from petals and pollen, to enable them to germinate and infect the plant. Plant infection also requires long periods of high humidity and night-time temperatures above 7°C. Sclerotinia spreads from leaf lesions to the stem. Stem lesions increase in size, girdling the stem resulting in premature ripening and weakening stems.

Eventually, stems can lodge. New sclerotia are formed within the stem cavity and roots. These are often returned to soil at harvest.

Risk factors

• Rotations (short rotations, especially those that include other susceptible crop hosts increase the risk)

• A history of previous sclerotinia infection on-farm • Favourable weather (e.g. mild day and night temperatures with light rain or dew)

• • • •

Crop growth stage (crop in flower) Presence of sclerotinia inoculum Germination activity of sclerotia ungicide choice and timing (protectant fungicides need F to be applied before infection to achieve good control)

Management It may be necessary to extend rotations at sites with severe epidemics.

Fungicide timing is important for good control, as products available to control sclerotinia stem rot are protectants and have little or no curative activity.

The optimum timing for a single spray is, usually, just before mid-flowering on the main raceme and prior to significant petal fall. Treatments provide good control for about three weeks. Two sprays may, therefore, be required to protect crops at high risk sites throughout the flowering period (especially when the flowering period is extended).

Fungicides differ in their physiological effects on the crop and also efficacy against other diseases that may require control during flowering (e.g. light leaf spot). Whether additional disease control or growth regulation (e.g. to decrease lodging risk) is required should be considered when selecting products.

Strategies are required to minimise the risks of selecting for fungicide resistant strains of sclerotinia and other pathogens.

No resistance to fungicides has been reported for sclerotinia and likelihood of it occurring can be decreased by using mixtures, co-formulated products and products with a different mode of action throughout flowering and the whole fungicide programme. Strains with decreased sensitivity to SDHIs and MBCs have been reported in France demonstrating the importance of implementing strategies now. It is important that fungicide resistance management guidelines are followed (e.g. do not rely on a single mode of action for sclerotinia stem rot control).

GRAIN MARKETS 2022 – DEALING WITH UNCERTAINTY Written by Donal Moloney

While every harvest year or growing season carries a level of uncertainty, it is probably fair to say that 2022 looks like overshadowing most, if not all years in recent memory, in regard to the unpredictability that lies ahead, particularly with regard to grain price. At this stage, all growers will be well aware of the surge in input prices over recent months, in particular fertiliser and fuel prices. Input price increases and possible product availability issues look set to remain with us in the short to medium term at least.

Thus far, grain price has also maintained a strong upward trajectory, boosted in recent weeks by the Russian invasion of Ukraine. In theory, strong output prices could outweigh high input prices; however, this equation is fraught with risk in that growers will incur the bulk of their input costs in spring while it will be several months later before crops are harvested and the value of output can be counted. While it is easy to view grain markets as only “going one way”, history has taught us that markets never remain one-directional indefinitely. Much of the current focus is on the likely reduction in Ukrainian grain production, specifically maize in 2022, as well as the curtailment of exports from that region. While Ukraine is one of the world’s major grain-producing regions, it is obviously not the only one. It is worth noting that Brazil is currently on track to increase its maize production by as much as 30m tonnes compared to 2021; Brazil’s main maize crop was decimated by drought last year but this year’s crop has been sown on time in excellent conditions and has received favourable weather to date.

Figure 1 is an extract from the 2022 Crop Costs & Returns booklet published by Teagasc and updated to take account of recent movements in both input and grain prices. The extract shows gross margins for the main cereal crops at different yield levels. Even with the huge increase in input prices in 2022, growers achieving average yields will attain reasonable margins while those hitting high (target) yields could be well on the way to having quite a profitable year. The graph in Figure 2 supports this argument showing that current prices available for green grain compare favourably with the corresponding cost of production when set against previous years.

The main conundrum of course is that the grain prices shown in Figures 1 and 2 may not be available at harvest; they may well of course be higher but is that a risk worth taking? Forward selling a proportion of their crop allows a grower to take advantage of high prices well in advance of harvest and in so doing, lock in a margin on that quantity of grain. The most prudent approach to forward selling is “little and often” – nobody can know when the market has peaked until well after the event. For any grain grower, it is the average selling price achieved across a season that is most relevant, not the highest or lowest prices. Many growers will comment that forward selling is a “gamble”; however the real gamble for 2022 is waiting until harvest to see how price develops as the investment in inputs has never been higher.
