Managing Soil Fertility with Organic Amendments

Why We Care About Carbon

y definition, anything that was or is alive is considered organic matter because it contains carbon-based compounds. This article covers some of the considerations around using organic soil amendments.

The most common types of soil organic amendments are manure, compost, and crop residue (including cover crops).

Soil carbon is important in all farming systems because of the role it plays in building and maintaining soil microbial communities. Soil microbes are critical for nutrient cycling and building soil structure because soil aggregates are held together by organic compounds produced by microbes, by fungal

This produces soil that’s resilient and efficient at providing nutrients.

And it increases humus and soil organic matter.

hyphae, and by plant roots. In addition, soil microbes are responsible for many parts of the N cycle, like converting ammonium to nitrate, the form of nitrogen most commonly taken up by plants. Even if there is sufficient total N in the soil, microbial processes will be slowed by reduced activity due to low soil carbon, cold soil temperatures, or inadequate soil moisture.

The amount of carbon to nitrogen (C:N) affects microbial breakdown of organic amendments, and thus potential nitrogen (N) release. Like us, microbes have dietary needs that have to be met.

The ideal diet for microbes has a C:N ratio between approximately 20:1 and 25:1. Nitrogen is present in the soil and in soil water. When microbes consume material with a higher C:N ratio than their ideal diet, they will “mine” N from the soil profile for their own use, making it unavailable (sometimes called “tied up”) for crop uptake. It is not permanently lost from the system as with N leaching or volatilization. Rather, it is unavailable in the short term until the microbes die. When microbes consume materials with a lower C:N ratio than their ideal diet, they release the N that is in excess of their dietary needs that is immediately available for crop uptake.

Amendment Selection

Material Efficiency: The C:N ratio of the material affects both the amount of N that will released for plant uptake, and the time in which the N will become plant available. Materials with a lower C:N ratio are broken down more rapidly and a larger proportion of the N will become available during the growing season. Materials with a higher C:N ratio are broken down more slowly and a lower proportion of the N becomes available. These materials need to be applied in larger quantities and earlier in the season to meet crop N demand during peak uptake. In contrast, the nitrogen in materials with a very low C:N ratio, such as feather meal, guano, or some liquid products, becomes available very quickly. These products provide the opportunity for in-season applications through fertigation or side dressing, similar to synthetic fertilizers.

Material Costs: With organic amendments that are high enough in N to be used as an N source, cost per unit available N is more relevant than cost per unit weight. However, this may not be the only consideration. How much the material costs to transport and spread can eat into your bottom line quickly.

Watch for percent moisture because this affects nutrient calculations (which should be based on dry weight) and it’s expensive to move water.

Calculate the true cost of organic amendments when deciding what material to use, including percent moisture. This includes product versus management costs to estimate how much a pound of N actually costs with each product for the growing season. In the short term, the goal may be to meet the demand of your current crop. In the long term, the goal is to build soil structure and fertility.

Management Considerations: Fresh manures can contain a large proportion of ammonium-N and can lose a substantial amount of N to the atmosphere if they are not tilled in soon after appli6

A Focus on Compost

including reducing erosion, increasing water holding capacity, and moderating soil temperature. For these reasons, compost can be an excellent soil builder and can lead to improved soil function, but it is important to evaluate the properties of the compost before application and know what you are using it for.

Compost is any product that results from the decomposition of organic material. Since the material that goes into compost can vary widely from food and yard waste to wood chips to animal manure, the fertility and benefit to agronomic productivity is also quite variable.

225 lb. N required ÷ 0.35 = 643 lb. N/A needed to apply to meet corn demand.

Given the amount of N in each ton of compost, you will need to apply: 643 lb. N/A ÷ 44 lb. N/ton = 14.5 tons/A of compost (29,000 pounds of material).

This means, that you are applying 8 to 14 times more P in one year than your crop needs! Consider the nutrient loading that will occur if these elevated manure levels are applied year after year to meet the crop N demand. While it is unlikely that anyone would apply this amount of material to a field in one growing season, this example can serve to highlight the considerations for managing fertility organic amendments.

How much phosphorous will be in that compost application?

14.5 tons x 26 lb. P/ton = 377 lbs. of P/A (this is 867 lb. P2O5) According to California fertilization guidelines, P should be applied based on crop removal and 60 to 80 pounds of P2O5 are removed when corn grains are harvested from the field and 60 to 100 pounds with silage corn.

It can be challenging to balance nutrients with organic materials and, when possible, consider other sources of amendments with different levels of NPK. While there is no inherent risk in having too much P to your crop, P contaminates waterways when soil moves off the field through erosion or runoff and is one of the main drivers of eutrophication. In addition, some organic amendments can be high in salts and can lead to salt build up in time.

Efficient application of organic amendments is important. In certified organic systems, consider incorporating legume

cover crops into your rotation to ensure adequate soil N levels while reducing the risk of overloading other nutrients. Non-legume cover crops can also improve nutrient cycling and reduce the risk of nitrate leaching.

If organic amendments are added consistently year after year, the soil structure is improved, which reduces the risk of soil erosion. In addition, N cycles can become tighter. The 65% of N that wasn’t mineralized in year one in the example above may become available in future years although this is hard to account for in N budgeting. Organic amendments can build microbial activity, soil structure, soil fertility, and soil health. However, it can be more challenging to manage them to meet annual crop N demand than with synthetic N fertilizer.

Consumers demand a superior taste and eating experience from their organic table grapes – a crisp, firm bite with texture, flavor and sweetness. They also want long shelf life. Grocery stores want less shrinkage. Growers need high marketable yields of superior quality fruit to maximize per acre returns.

Agro-K’s CLEAN line of nutritional products and application program is designed to deliver – superior eating quality consumers demand, less instore shrink grocers demand and maximum marketable yields growers require.

The second part of the consumer taste experience is flavor which is driven by brix, aromatics and flavonoids. To achieve high yields and full flavor requires the vine have large, fully functional leaves and maximum chlorophyll. The key nutrients: magnesium, manganese, iron, copper and zinc are needed as the leaves are forming and expanding to ensure sufficient leaf surface area and maximize chlorophyll function to drive optimal flavor, texture and shelf life. Allowing you to put the best finish on a quality bunch.

The first part of a superior eating experience is the bite. It needs to be firm and crisp on the outside with good structural integrity on the inside.

Maximizing calcium uptake into fruit cell walls during fruit cell division is critical to maximizing grape skin cell-wall thickness, internal flesh firmness and shelf life (minimizing shrink). Managing the N/Ca ratio is critical to growing firm fruit that stores well. CLEAN Cal is designed for rapid and complete uptake to help growers deliver that “first bite” experience in fruit that also stores better on the grocery store shelf and longer at home.

Agro-K’s CLEAN line of certified products gives organic growers the ability to meet “peak nutrient demand” in a form that goes in to tissues quickly and completely, resulting in superior fruit quality and yield. Plant physiology drives nutrient timing and understanding this timing gives growers the ability to address peak demand timings and maximize fruit quality and profitability. Use the right nutrients, at the right time, in the right form for the highest yields and best quality.

Talk to Agro-K or your authorized distributor today about how CLEAN can help you achieve higher yields of superior fruit.

BIOLOGICAL CONTROL OF BROWN MARMORATED STINK BUG

By DANITA CAHILL | Contributing Writer

R

esearch in the Pacific Northwest is focused on finding biological and softer alternatives to control brown marmorated stink bug (BMSB.) The BMSB is an invasive species from Asia that first appeared in the U.S. in 2010 and has since spread and become a significant problem in Oregon.

The samurai wasp, Trissolcus japonicas, is a natural predator of BMSB that followed its host from Asia to the United States. In Asia, the wasp takes care of 60 to 90 percent of BMSB eggs.

“We found the wasp in downtown Portland; we started moving it around,” said Oregon State University (OSU) Extension Orchard Specialist Nik Wiman.

Populations of the samurai wasp have shown up in other states, including Washington, New York, New Jersey, Delaware, Maryland, West Virginia and Washington DC. The populations are not genetically related to the others, so each is showing up on its own, not simply breeding and migrating.

Parasitized Eggs

Since the wasps are so tiny – approximately the size of the period at the end of this paragraph – the easiest way to check for their presence is by monitoring BMSB egg masses on the underside of leaves. Egg masses are green to blue-green, barrel-shaped clusters. Because of their color, they are hard to see. When the eggs are parasitized by the samurai wasp, they turn black and should be left alone. Blackened eggs are also easier for the human eye to spot. The wasp larvae feed on the BMSB larvae, killing the stink bugs before they hatch.

Wiman and other scientists have collected and analyzed wild, fresh and 10

frozen BMSB egg masses. The researchers are seeing an increase in parasitism from the samurai wasp. In 2018, they saw a 22.4 percent rate of parasitism.

In 2019, that number increased to 26.8 percent.

Raising and Releasing Wasps

The researchers are raising the samurai wasps in an OSU lab to target-release in specialty-crop areas.

“When we go out to release, we look for natural areas that don’t have insecticides,” Wiman said.

He said the 1- to 2-millimeter stingerless wasps have spread about six miles per year and researchers are hopeful that with continued lab work and research they can strike a healthy samurai wasp/BMSB balance.

BMSB Detection and Spread

The brown marmorated stink bug – marmorated means marbled or streaked – was first detected in the US in 1998 in Pennsylvania. It has since become a serious pest in apple, pear, stone fruit and hazelnut orchards in the Pacific Northwest. It feeds on about 100 different varieties of plants, including many agricultural crops, such as grapes, peppers, tomatoes, corn, squash and soybeans. BMSB also causes issues with some shade trees, such as maples.

The BMSB has been a problem in hazelnuts since 2004, according to Wiman. Researchers, growers and processors have seen 5-15% BMSB damage in hazelnuts over the past four-year period.

OSU Statewide Organic Vegetable Extension Agent Nick Andrews said he’s seen BMSB damage, “intermittently in vegetables.”

April/May 2020

The BMSB probably arrived in the United States aboard international shipping crates. After its arrival, the stink bug quickly began expanding its territory, spreading across the states. In 2010, the pest caused 37 million dollars in lost apple crops in the Mid-Atlantic States. Also that year, more than 90 percent of some stone-fruit growers’ crops were lost. By the end of 2010 and into 2011, the BMSB had become a serious pest in orchards along the Eastern states. This stink bug variety has now spread and established itself in many parts of North America – 42 states from California to Maine. In Oregon, the BMSB is a severe problem.

It’s also causing agricultural issues and is considered a nuisance in California and Washington State.

Feeding Damage From Nymphs and Adults

“The nymphs are a huge part of the problem,” Wiman said.

A true bug, both the BMSB nymphs and adults use their tubular mouthpiece to pierce developing fruits, vegetables, nuts and seeds. They inject saliva inside, making a sort of slurry, which they then suck up through their straw-like mouths. The insect damage creates unsightly brown spots inside the kernels of hazelnuts. Damaged fruit shows a dimpled appearance on the skin. Inside are brown areas of rot.

BMSB are speckled grey and brown, with white bands on their antennae and a triangle shape on their back called a scutellum. They are a fairly large bug, broad-bodied and up to 1-inch in length. BMSB cannot sting or bite, but

Stink bugs spray a noxious odor from their abdomen as a defense mechanism.

They live for 6-8 months. Females can lay up to 400 eggs during their lifetime.

Other OSU Research Discoveries: • BMSB show a disconnect between feeding and responding to pheromone traps.

• Early season response to traps is poor.

• Warning: Bringing pheromones into the orchard can cause damage in the trap vicinity. Aggregation pheromone attracts all the insects.

Keep them out along the border.

• Traps are useful for detection, but they don’t take the place of scouting.

•

Exploiting pheromones to

attract-and-kill, or for mass-kill sites needs more research.

Control is Elusive for BMSB

Insecticides which are effective for BMSB are nearly all broad spectrum and restricted use, Wiman said.

Tests have been done with baited sheets of netting treated with pyrethroid. There have also been experiments done using light as a way to attract BMSB to such a kill site. The problem? Getting the BMSB to land on

Continued from Page 12 the netting and stay there long enough for the pesticide to do its job.

“Get BMSB to land for about one minute on the netting and it will die,” Wiman said.

Conventional growers can use pyrethroids and pyrethrin, but he says they aren’t all that effective on BMSB. Also, by using insecticides, growers risk killing the beneficial samurai wasp.

“We found the samurai wasp is really sensitive to pesticides. Entrust™ was one of the most toxic,” Wiman said. “It affects the diamids, which is the softest materials of the wasp.”

For smaller organic farms, exclusion is likely the best way to keep stink bugs at bay with the use of particle films, tunnel row covers and other barriers.

Kaolin clay, or Surround, also helps discourage insects. The spray-on clay coating won’t kill the insects, but it irritates them, and they don’t like it, Wiman said.

Unfortunately, BMSB is nearly impossible to control.

“You don’t have control,” Wiman said. “It’s coming from the environment. You can be the best manager, but you still can’t control the BMSB.”

Plant Wasp Habitat

“Urban areas put out a lot of stink bugs,” he said, as do riparian zones and forests. So, farms near those areas are bound to experience issues with stink bugs. If allowed to flourish, the wasps will likely show up in these areas as 14

well.

Researchers are looking at what plants attract the wasps. Samurai wasps that were fed honey water in the lab tended to grow faster and show signs of better health.

“They probably enjoy floral resources,” Wiman said.

That steers the organic grower toward planting flowers, either within the orchards or along the borders. He said the flowering plants don’t necessarily have to be native to attract the wasps.

One Grower’s Experience with BMSB

Joe Beaudoin, of Joe’s Place Farms in Vancouver, Washington said BMSB arrived on his property 4 to 5 years ago.

Beaudoin said he was the first farmer in Southwest Washington affected by the stink bugs.

“Oregon State University and Washington State University were out at our place for four years,” Beaudoin said.

The first thing the BMSB hit was his peppers. Then they moved on to other fruits and vegetables.

“They sting with their proboscis,” Beaudoin said. “One sting in a pumpkin or squash pretty much destroys them. There’s no repairing the damage.”

The stink bugs also hit his cherries, berry crops and peaches. He noticed the BMSB were variety specific in what they attacked. He has PF 23 (Flamin’ Fury) peaches and Suncrest peaches growing next to each other. Both are yellow, freestone varieties.

“The PF 23 was 100-percent ruined,” he said, but the Suncrests – a hardy

variety bred in Fresno, California – were virtually untouched. Beaudoin grows 15 different varieties of peaches all together. “The PF 23 – they liked it the best.”

He noticed that the BMSB had preferences in his pear crops, too, preferring the russet (brownish) pears rather than green pears.

“It’s kind of strange,” Beaudoin said.

Then, for the most part, the stink bugs moved on.

“They moved into apple country,” Beaudoin said. “They went east into the valley. They’re moving out and spreading out.”

The amount of damage to produce crops at Joe’s Place Farms has recently diminished.

“We have not had that much damage,” he said of last growing season.

As for the reason the stink bugs hit his farm first? Beaudoin figures it’s because he is located close to an airport.

The Pacific Northwest has not been as hard hit by BMSB as the East and the Midwest, according to Beaudoin. He heard the story of one farmer in the Midwest who drove his tractor for the day through his fields. At the end of the day, “He got a five-gallon bucket full of brown marmorated stink bugs out of his air filters.”

ROADMAP TO AN ORGANIC CALIFORNIA

By LAETITIA BENADOR | Research Fellow, California Certified Organic Farmers (CCOF)

H

ow can we use organic farming to solve the biggest problems of our time? A first-of-its kind research project from California Certified Organic Farmers (CCOF), the Roadmap to an Organic California (www. ccof.org/roadmap-organic-california) investigates how organic is a solution to today’s toughest challenges from climate change to economic insecurity and health threats.

The urgency of addressing these challenges demands building on what already works. As a first step, CCOF asked: what does the science say about organic? The Roadmap to an Organic California: Benefits Report, the first installation of the project, examines three decades of peer-reviewed science on organic food and farming. The science is clear: Organic farming, with its tremendous capacity to pull carbon out of the atmosphere and store it in soils and its unique ability to stimulate the economy while feeding the world’s population with nutritious foods, is a proven and practical solution to stabilize our climate and communities.

laid out in the Roadmap to an Organic California: Policy Report that serve as a blueprint for putting organic to work.

The Policy Report provides actionable next steps for legislators, business leaders, and community organizers to use organic to build climate resilience, foster strong communities, and protect the health of all Americans.

Organic farmers have pioneered many of today’s climate-smart farming practices that reduce greenhouse gas levels in the atmosphere and make farms better adapted to extreme weather. Long-term comparison studies demonstrate that organic soils are healthier, enabling them to draw down 14 times more carbon than conventional soils. With the world’s soils capturing 25 percent of annual fossil fuel emissions, organic agriculture is in a unique position to maximize the amount of carbon stored in soils in order to stabilize our climate and food supply.

Based on these findings, CCOF developed nearly 40 policy solutions 16

Organic is a Climate Solution

April/May 2020

Despite the proven ability of organic to help solve the climate crisis, organic is not integrated into California’s climate strategy. The Policy Report

details next steps that we can take to use organic to foster climate resilience by advancing climate-smart agriculture programs, conserving organic farmland to maximize carbon sequestration, and investing in organic research in order to build on the resilience of organic farms and refine the practices that help farmers producer higher yields in a changing climate.

Organic is an Economic Solution

The organic market stimulates the economy by creating business opportunities, growing jobs, and reinvesting dollars in local communities. Organic sales are growing faster than all other food sales and generating diverse careers and entrepreneurial opportunities in urban and rural communities alike, from organic seed farms, to organic snacks, to meal kit delivery companies.

By keeping food dollars local, studies demonstrate that organic businesses can increase household incomes and alleviate poverty as much as federal nutrition assistance programs like the Supplemental Nutrition Assistance Program (SNAP).

Though organic is a proven economic stimulus, barriers to the expansion

organic requires all hands and boots on deck. Organic is a holistic approach to growing our food that impacts every aspect of our lives, from the water we drink and soils in which we grow our food to the economy and our community’s resilience in the face of climate change.

This message is what brought organic farmers to the California State Capitol on Feb. 19 together with business leaders, schoolteachers, healthcare professionals, scientists, and climate advocates.

Organic is a Health Solution

Organic food protects people and the planet. Hundreds of crop comparison studies show higher levels of vitamins, minerals, and antioxidants in organic foods. However, human health is determined not only by the nutritional quality of the food we eat, but also by how our food made it onto the plate.

In addition to being highly nutritious, organic safeguards our drinking water and combats the health impacts of climate change. Organic promotes overall health for all Americans and for future generations.

While many Americans choose organic to keep their families healthy, too few communities have access to the health benefits of organic.

THE KEY TO OPTIMUM SOIL AND PLANT HEALTH:

GIVING LIFE TO THE SOIL

By NEAL KINSEY | President, Kinsey Agricultural Services

T

hose who study life in the soil point out that the population of beneficial living organisms that grow and thrive there determines to what extent that soil will grow and produce abundant, healthy crops. The life in the soil and the health of the soil are intertwined. To determine what promotes the greatest amount of life in the soil will also then provide the greatest support for soil health.

Time after time, the healthiest soils are found to be those with the most active living organisms. Soil life is a major factor in determining soil health. The most critical needs for sustaining all life are also the most critical to life in the soil. Assuring the correct amount of life’s most critical requirements is the real “trunk of the tree” in regard to building better soil health.

There are four basic needs for life – shelter, food, water and air. Which one of these on average can more likely be missing and life could go on the longest? First would probably be shelter, then food, then water, then air. Air is the most critical of all since we can only live a very short amount of time without it.

Air in the Soil

When considering clay soils, much like the human body, insufficient air is considered one of the most significant problems. This is usually caused by too much water in the soil, which prevents the air from reaching to the proper 18

depth causing interference in microbial activity. Far too many individuals working in agriculture fail to recognize the significance of the correct amount of air needed in the soil, let alone the methods that must be involved for correctly solving this problem when having sufficient air is not the case. That may be one of the reasons it is not pointed out as the greatest problem affecting soil life and soil health.

Just how important is air for soil health? It is a major key for humus formation. Humus is formed within the soil’s aerobic zone. The aerobic zone is the depth of soil to which air remains

sufficiently available for the most beneficial microbial activity and good plant health in each different type of soil.

Due to the abundance of air, microbiologists say that on average

Soil textbooks teach that the physical structure of an ideal soil is made up of 50% solids and 50% pore space. Ideally, the solids part is comprised of 45% Minerals and 5% Organic Matter, while the pore space portion is comprised of half Air and half Water. However, those same textbooks do not tell what changes are needed in order to help soils that are lacking it achieve that correct physical structure.

Continued from Page 18 70 percent of all humus is formed in the top two inches of soil. Ninety-five percent of humus is formed in the top five inches, and 100 percent is formed within the depth of each soils’ aerobic zone.

One good measurement to determine each soils’ aerobic zone (how deep the microbes that depend on air can get enough to live and function) is to remember that it as deep as a fencepost will rot in each particular soil. This is generally between 6.5 to 8 inches deep.

How many people who advocate for building better soil health even consider providing an adequate amount of air to the soil as the most critical step to building excellent soil health? And even so, if the soil lacks aeration, is there anything that can be universally done to change or correct that lack?

Changing Soil Structure

Air is needed to keep a healthy set of microbes to supply plant nutrients and build humus in our soils. But what can be used to determine if the correct amount of air – not too little and not too much – is present?

This is an important question that too few can answer. When soil aeration is lacking, how can farmers and growers detect that actually is the case? What provides the proper amount of aeration to the soil to best promote soil life and soil health? There is a way to determine this answer that many in agriculture reject because it does not 20

Organic Farmer

translate into immediate sales and profits, though it is very profitable for the farmer and the land in terms of soil health.

That answer has to do with measuring and correcting the physical structure of each different soil. The physical structure of a soil (how well it works up, takes in water and provides the needs for plant roots) determines the amount of air and water that is present in relation to the soils’ mineral content.

The ideal soil has a specific physical structure. That is 25 percent air, 25 percent water, and 50 percent mineral content - of which 5 percent or more of that mineral content would ideally be humus (see related pie chart).

Textbooks on soil science illustrate the physical structure of an ideal soil as 50 percent solids and 50 percent pore space. However, none of those books go on to provide what changes are needed in order to enable soils that are lacking such qualities reach that correct physical structure.

Achieving the ideal physical structure for each soil – the proper amount of air in relation to water in each soil – can only be correctly determined by measuring the percentage of saturation of the elements that have a major influence on pore space in that soil.

To correctly understand and farm the soil, those elements are calcium, magnesium, potassium and sodium.

In order to bring the physical structure of a soil into alignment with the textbook definition of an ideal soil; first measure and adjust the base saturation percentages of calcium, magnesium, potassium and sodium to match the correct percentages needed for the total exchange capacity (TEC) of that particular soil. The pie chart in this article shows those needed relationships.

April/May 2020

Making any needed corrections will help promote the proper nutrient uptake, the proper physical structure, and the ideal biological environment

for the soil and the crop.

In other words, to optimize needed soil aeration the correct relationship between specific elements, namely calcium, magnesium, potassium and sodium must be achieved. When there is too much of any one of these, there will usually be too little of one or more of the others. Until any excesses or deficiencies of any of these four elements are corrected, the soil will not have the ideal amount of air in relation to water.

Since calcium and magnesium are by far the most needed and thus provide the most influence of the four elements involved for building the proper soil structure, always consider correcting them first. This is the place to begin if soils do not already have the ideal physical structure and thus the ideal amount of air to provide for optimum biological activity.

Balancing Calcium and Magnesium

Before correcting calcium and magnesium levels, there are three basic points that need to be understood.

First, the base saturation percentage of calcium plus magnesium always needs to equal 80 percent in order to achieve the correct physical relationship between air and water in the soil. In other words, the proper relationship between calcium and magnesium ultimately determines the friability of each soil – whether it is too tight or too loose or works up as it properly should.

This relationship applies to every soil with a TEC of 4.16 or higher. (Lower TEC soils must be treated differently and require a separate course to explain all the differences to consider.)

The second point is concerned with the reaction of calcium and magnesium to one another in terms of changes in the soil’s base saturation. The change is generally expected to be 1:1. This means that for every 1-percent increase in calcium, the magnesium will decrease by 1 percent. And also, for every 1 percent magnesium goes up

Continued from Page 20 without adding more calcium to counteract it, the calcium will decrease by 1 percent.

(But watch higher TEC soils. Some have magnesium trapped between the layers of clay, while others may have an abnormally high pH, or percentage of potassium or sodium that affects magnesium availability.)

NOW Monitoring System!

Here is the basic foundational key to excellent soil health: Work to supply each soil with the proper amount of needed air and that soil will be most equipped to perform at its best. And only a detailed soil analysis will provide the necessary information to show what is needed to promote the needed air in each soil.

Cover crops, compost, adding carbon and nutrients can all help contribute to soil health, but until there is enough air in the soil, that most critical component will still slow the way to excellent soil health.

Once the required percentages of calcium, magnesium, potassium and sodium are met, then the soil chemistry is working at its best and providing the proper physical structure for air and water to function as they should due to well aerated soil. Will it always be perfect? No. Too much rain can reduce aeration, not enough water can cause problems as well. But once the soil nutrients are there in the correct proportions, only then does the soil have the best means of re-adjusting to the most ideal conditions in the shortest period of time. Until the conditions are met for proper aeration in each soil, there is no chance of achieving what is needed for an ideal in terms of soil fertility and plant health.

CHOOSING HEMP VARIETIES COMMERCIAL HEMP SEED PRODUCER OFFERS ADVICE ON SELECTING AND GROWING HEMP

By DANITA CAHILL | Contributing Writer

A

Choosing Varieties

s larger commercial growing operations move into hemp as a rotational crop, breeder James Knox of KLR Farms offers some advice to boutique growers for selecting the right variety and competing in an increasingly crowded field.

KLR Farms has hemp hybridizing, research and development facilities, and hemp-seed production farms in several locations in Oregon, and more recently, a collaboration on a six-acre indoor grow facility in Illinois. It recently partnered with a distributor in Tennessee.

Organic Farmer

Knox said the first step is to select the right variety. He said growers should consider the following when selecting a variety: Understand your region and your growing season. Instead of picking the prettiest varieties, choose varieties suited for your location.

If you tend to have a wet fall in your region, choose mold-resistant strains.

You want a variety that will survive the end of the season, whatever that means

weather-wise in your region. In Oregon and parts of Washington, harvest is generally in October – affectionately called “croptober.” It’s often an October harvest even for plants labeled as early flowering. Knox said.

In 2019, Knox harvested his personal research and development, 25-acre inground plot, from Oct. 18 through Nov. 11. He said his plants were still putting on mass and girth through October.

Knox sold seed for 200 to 300 acres of

planting 5,000-20,000 seeds per acre, typically drilled into the row.

Overhead water, such as cannons or pivots works with this type. These plants grow 9-14 feet tall. Harvest at 4-6 weeks into flowering by combining the top 3-4 feet, which is basically one big flower head. Cut the rest of the plant and lay in windrows.

Use the top for oil and the rest for fiber. Some uses to consider for the fiber is dried and chopped for animal bedding, garden mulch, or use as green manure. Bag and sell it, or use it on your own farm.

Hemp Compounds and Components

Hemp plants grown from cuttings.

Sativa

Continued from Page 24 hemp to California farmers.

“They have more light, more heat and a longer growing season, especially in SoCal. They were literally harvesting into December,” Knox said.

Tall plants with smaller, thinner, finger-like leaves. Takes longer to flower than Indica, generally 6090 days outdoors. Use drip tubes or tape to water. Originated in Africa, Central America, Southeast and some parts of Western Asia.

Plant genetics are studied in depth at Knox’s operation. He has a PhD plant geneticist on staff. Feminized-seed plants are not genetically modified, Knox pointed out.

In 2019, KLR Farms launched its offerings of hemp seed to the open market – nationally and internationally.

They offer four different Sativadominant hybrids and five different Indica-dominant hybrids. One of the Indica varieties is an auto flowering/ auto hemp. This year they are also releasing three different Sativa hybrids that are dual-use fiber/oil varieties.

There is more to hemp than CBD. There are many other compounds and chemicals to consider when choosing varietal strains.

THC

Is the main psychoactive compound that produces a “high.” Hemp grown for CBD oil is tested before harvest to make sure THC is .3 percent or less.

Indica

Dense, bushy plant with wide leaves. Shorter time to flower, usually 45-60 days. Good choice for indoor growing, but can also be grown outdoors. Use drip tubes or tape for watering.

Originated in Afghanistan, India, Pakistan and Turkey.

Auto Flowering

KLR is collaborating with Sovereign Fields, located in Southern Oregon, on their offering of this variety. This type of hemp is day neutral and flowers without shorter daylight.

Fiber/Oil Dual-Use Hemp

This is something new on the market. In 2020, KLR Farms is introducing three new varieties.

CBD

The non-psychoactive known for reducing pain, nausea, easing migraine headaches and preventing seizures.

CBN

Cannabinol is touted to ease symptoms of neurological conditions and muscle stiffness.

THCA

Tetrahydrocannabinol acid is similar to THC, but without the psychoactive effects. THCA may relieve inflammation from autoimmune diseases and arthritis.

It may also reduce the symptoms of ALS and Parkinson’s disease.

Advice on Growing Hemp

• Know the origin of your seed. Buy good feminized seed.

That means buying and using your own equipment to plant and harvest. Have your own dryer, storage facility and oil extractor, or be prepared to ship it out to a processor. Plan ahead for labor needs and costs. Have your fertilizer plan lined up. In addition, he offered the following suggestions:

• Test plant tissue throughout the season to monitor the chemical values.

“Go vertical,” Knox said.

• Try to be in control of the crop and process from start to finish, without outsourcing if possible.

Continued on Page 29

CBG

Cannabigerol may help with anxiety, post-traumatic stress disorder, depression and obsessive-compulsive disorder. This compound is beginning to get more attention, but the market is not yet mature, Knox said. If CBG is something you want to shoot for producing, he suggested planting no more than 30 percent of your acreage in CBG-rich varieties.

Terpenes

These are another natural compound found in cannabis. They affect the way the plant smells.

KLR Farms' best-known variety is KLR #1, or CherryLimeadeHemp, named for its “pungent and complex sweet cherry, with strong essence of lime and skunky pine.” It’s a Sativa-dominant hybrid and one of KLR’s best all-around field producers. An aggressive grower, it’s got strong stems and stocks to hold up well outdoors in wind and weather, but also grows well under lights. It’s a bit later to flower than some of KLR’s other varieties, but flower biomass is heavy at end of season. If bud rot is a problem in your region, with wet fall weather or high humidity, this is a very mold-resistant variety. Raw flower biomass consistently tests at a 16-22 percent total CBD value.

Continued from Page 27 Big farmers are perched and ready to enter the hemp industry, Knox predicted.

“They’ll use hemp as a crop rotation.

They’ll treat and sell it as a large commodity for companies looking to add CBD to their product line,” Knox said.

If Knox’s prediction proves correct, that will leave smaller, craft farmers scrambling to find their own value-added market niche. Knox points to the success of Oregon micro-breweries as a business model to emulate.

To help the industry, Knox said, “We have to increase the CBD amount per volume and bring the price down.”

Feminized seed is the best investment.

Open-pollinated seed will contain males. Males produce pollen. Pollen blows on the wind and can make other growers’ hemp seed out, which ruins the crop.

“It’s always important to look at past years’ historical crop data.

Look at the past three years,” Knox said. “Pay attention to all of those commercial crops grown in your region. Kind of gauge your year off of it.”

LESS DAMAGE – MORE PROFIT SEASON-LONG CONTROL THROUGH POST-HARVEST

“Sixty-six percent of the chemical (CBD) is taken away because of that seed,” Knox said. “You do not want a seeded-out hemp crop, ever. Feminized seed is the most reasonable and responsible.”

Be a good farmer. Know, or learn how to manipulate water and fertilizer. You may need to coax plants into early flowering if the season is looking questionable, weather-wise.

Spend the few dollars on a current copy of the Farmer’s Almanac. Read it, especially the seasonal weather forecast.

“It’s as accurate as any forecast out there,” Knox said.

Pay attention to what grows well during the years that hemp doesn’t grow well.

For example, 2019 was a bumper crop for grapes, but not such a great crop year for many hemp growers. This year is forecast as another good grape year.

That means history is pointing towards another potentially challenging year for hemp farmers.

UC STUDENTS BREED BEANS FOR ORGANIC FARMING

raduate students at the University of California, Davis are making a very rare commodity available to organic growers: high-yield, disease-resistant bean varieties that can thrive on organic farms. A half-dozen new dry bean varieties that were bred at the University of California, Davis to be disease-resistant, hearty and high-yielding are now or soon to be available for commercial production.

And, because they were developed through traditional breeding techniques, they are suitable for organic production.

“Most crops—about 95 percent—have been bred for conventional farming and can be difficult to grow in organic systems,” said Travis Parker, a doctoral student in plant biology who is part of the project. “These new bean varieties could make a big difference in performance and profitability of organic legumes like pinto, black and kidney beans, as well as heirloom-like varieties with high culinary quality.”

There are five new bean varieties being released now, and one that is going to get an additional year of testing. All have resistance to bean common mosaic virus and improved yields. They have been in field trials the past two years in growing regions throughout California should be well adapted to conditions across the Western U.S., Parker said.

center’s innovative efforts to train a new generation of plant breeders.

But conventionally bred beans can present a challenge for organic farmers. With limited use of herbicides, organic farmers have trouble controlling the weeds that battle young crops for water, sun and food.

“We want to give our plant-breeding students experience with real cultivar development that results in products that growers and seed producers want,” said Professor Charlie Brummer, director of the UC Davis Plant Breeding Center. “This project lets us put those pieces together in a very meaningful and exciting way.”

To address that, the UC Davis team are breeding fast-growing plants that can outcompete weeds. The new varieties grow tall enough to shade out weeds without tipping over to make it easier for organic and conventional farmers to use tractors to mechanically control weeds.

UC Davis doctoral candidate Travis Parker leads a student-run project to breed beans for organic production.
