IDAHO-MALHEUR COUNTY ANNUAL MEETING

Is a Backyard “Still” in Your Future? Recycling Drip Tape Story and photos by Dave Alexander, Publisher

I

f the thought of making moonshine in your backyard makes you read this article, then chalk one up for salacious headlines. We’re not going to give you any hooch recipes here, but if you use drip to irrigate, or plan to in the future, then read on. At the 64th annual meeting of the Idaho and Malheur County Onion Growers’ Associations held Feb. 6 in Ontario, Oregon, Marina Denny with Oregon State University (OSU) talked about how to address a big problem facing drip irrigators – what to do about used drip tape.

Every year, millions of pounds of drip tape are pulled from the ground. Rather than using the non-sustainable method of dumping it on the “north forty,” growers have limited options to dispose of the old tape. Most landfills won’t accept the tape, or will only take restricted amounts. Burning plastic releases dangerous gasses and is illegal in most states. There are companies in the Treasure Valley and Washington, such as Clearwater Supply, that will collect old drip tape and ship it out for recycling the plastic. Currently, this is the best option, but what if old tape could be converted to fuel for tractors on the farm?

From left, Dennis Atkinson, Jade Takehara and Jay Sutton man the Seminis booth in Ontario.

Pyrolysis

OSU has already built a small-scale, 1kg reactor (or still, as we like to say) to turn ag plastics into tractor-ready red diesel using pyrolysis. Pyrolysis, in this case, is the heating of plastic to extremely high temperatures to break it down and vaporize it. The vapor is then re-condensed into diesel. One kilogram of drip tape yields one liter of fuel. Does it make sense to build one of these open-source reactors on your farm? The construction only takes three components, and they are simple to operate and only need minimal maintenance. The idea is intriguing, but in reality, it will all come down to return on investment for growers. OSU will be working on ROI numbers soon. Perhaps a better solution is placing a large-scale commercial unit nearby. PDO Tech has a 500kg unit available that may be a solution for a grower collective or a single grower that uses a lot of tape. The company operates a reactor currently in western Oregon, where a lot of tape gets sent for recycling.

Sustainability

Vegetable processors and large retailers are already pushing for sustainability and zero-carbon footprint farms. If you are not currently recycling drip tape, it’s time to do it on your own before you are forced to. Plus, it’s the right thing to do and it opens up a lot of moonshine jokes. Denise Anderson, CEO of Clearwater Supply, is looking forward to plastic-tofuel technology, but she also knows there is much work ahead to get there. “As we look forward to the future, envisioning recycled products being

transformed into fuel represents a beacon of innovation and sustainability,” Anderson said. “Until such technology becomes both feasible and readily available, we must persist with other sustainable methods, ensuring our commitment to the environment remains steadfast and adaptable.” OSU estimates that there are 1.6 million pounds of drip tape used per year in the Treasure Valley alone. While that might sound like an immense amount of tape to get rid of, the plus side of this is that’s over 191,000 gallons of potential diesel fuel.

n recognition of their involvement in the onion industry, Brian Taylor and Charlie Morgan were inducted into the Treasure Valley Onion Hall of Fame during the annual meeting of the Idaho and Malheur County Onion Growers’ Associations. Brian Taylor

Brian Taylor was a longtime employee of Skeen Farms in Nyssa, Oregon. He took a job on the farm in 1984, beginning what would become a 38-year career and family-like friendship with the Skeen family. Taylor enjoyed learning and adapting to new ways of farming. As the years went on, he was known to be able to fix almost anything or have a shortcut that would make a repair go more smoothly. Taylor served on the board of the Onion Research Committee from 2004 to 2023 and as chairman from 2009 to 2023, roles he felt passionate about. He passed away in March 2023.

Charlie Morgan

Charlie Morgan enjoyed more than 30 years in the onion and potato storage business. After earning an associate’s degree in electrical technology, he began working for Argonne National Laboratory in Idaho Falls, Idaho, as a research technician and nuclear operator. Morgan became involved with onion storage in 1970 when he joined Industrial Ventilation Inc., a new startup. He was the company’s first fulltime employee, and he later became part owner. He is said to have been instrumental in designing equipment and methods commonly used in onion storage today. He retired from IVI in 2003.

Researchers Investigate Mechanical Harvest of Short-Day Onions

T

exas A&M AgriLife Research has received more than $5.2 million in grant funding from the U.S. Department of Agriculture’s National Institute of Food and Agriculture for a project to address multiple aspects of the southern U.S. onion harvest system. Subas Malla, an associate professor of vegetable breeding at the Texas A&M AgriLife Research and Extension Center in Uvalde, Texas, is taking the lead on the project. “The goal of this proposal is to improve profitability and ultimately market share for short-day onions by mechanizing short-day onion harvesting,” Malla said. The majority of onions grown across the southern U.S. are short-day onions, but their biology and structure present some difficulties, especially during harvest. “Dry matter content in the shortday sweet onion is low, but the water

harvesting have resulted in too many damaged bulbs to be acceptable for the fresh market. “However, these past attempts were limited to substituting the mechanical harvester for manual labor and did not involve a whole-system approach,” Malla said. The new project will involve the whole system and include short-day onion areas in Texas, Georgia, New Mexico and California to represent a full range of growing conditions. The University of Georgia, New Mexico State University and the University of California will partner on the project. The project will address many facets of developing a successful harvest system. These include identifying cultivars and production practices suitable for mechanical harvesting, modifying the harvest system to minimize the potential damage to onion bulbs, evaluating the influence of mechanical harvest on profitability and risk faced by onion growers, and communicating the benefits and drawbacks of adopting mechanical harvesting to growers. Malla said the adoption of any advances by growers will rely on partnerships with equipment manufacturers, seed companies and technology providers. A stakeholder advisory panel and scientific advisers will participate in the project’s proposed research and outreach activities. “We are already in the process of evaluating diverse Texas A&M onion germplasm to understand the genetic mechanism of host resistance against diseases and insects,” Malla said. “We are working with the Texas A&M Vegetable and Fruit Improvement Center to test bulb quality and storability in onions. We are also testing Texas A&M onion germplasm in a way that will help shorten the cultivar development cycle.” Malla said that to his knowledge, this project is one of the broadest and most comprehensive ever undertaken to address the challenges to short-day onion production. “Our ultimate goal is identifying the best cultivars and improving the short-day onion harvest system in a way that provides better results and better profitability for the producer,” he said.

Limiting factors such as compaction, poor soil structure, and salt accumulation reduce a plant’s rooting ability. RootRx™ has the capacity to reduce abiotic stress by increasing the quality and quantity of the root system. Key carbon compounds in RootRx™ facilitate an increase in antioxidant production which allows the plant to grow in the presence of these limiting factors without compromising the viability of the root system.

Why Onions in the Middle Get the Short End

By Denise Keller, Editor

percent difference in initial stand, 4,000 fewer plants per acre at the end of the season and 70 sacks per acre less yield. The difference in bulb size was less significant. In 2023, the inside rows yielded 120 fewer sacks per acre. “Think about that going back to stands. Usually when we have a thin stand, those onions blow up, they get big, they get bull necks. Here, we have less stand, yet the onions are smaller. So it’s not just the fact that we’re losing stand; the onions just aren’t growing as vigorously all season long for some reason and they’re staying small when we would expect that they would actually be bigger,” Thornton said. “I think that’s important enough to pay attention to. If I told you I could help you get 100 sacks more in yield or 5 tons more per acre, most people would say, ‘yeah, I’ll sign up for that.’” Stunting of onions grown in the inside rows of a planting bed, closer to irrigation drip tape, resulted in smaller bulbs (bottom row) compared to onions grown in the outer rows of a bed (top row).

D

o onions in the inside rows of a planting bed get the short end of the stick? Researchers in Idaho asked the question and say “yes.” Mike Thornton, a professor of plant science at the University of Idaho, has been studying differences in stand, yield and bulb size based on plants’ distance from irrigation drip tape.

Putting Numbers to the Observations

The work started after Idaho onion growers observed in 2019 that onions planted near drip line weren’t growing as well as onions planted farther from the tape. Researchers paid attention the following year and saw that, sure enough, onions closer to the drip tape were significantly stunted compared to the outer row. To determine whether the stunting

16

Onion World • March/April 2024

observed was substantial enough to impact onion growers’ bottom line, University of Idaho researchers began a study in 2021. Working with a 44-inch bed, they planted a double row of onions on each side of irrigation drip tape, with the inside rows 6 inches from the tape and the outside rows 9 inches from the tape. Two months after planting, the inside rows had a plant stand of 75 percent compared to 81 percent in the outside rows. Some plants were lost throughout the season, regardless of placement within the bed; however, at the end of the season, inside rows had about 9,000 fewer plants per acre than the outside rows. In addition, yield was 200 cwt per acre lower and bulbs were 2.4 ounces smaller, on average. Thornton’s team repeated the trial in 2022 with similar results: 11

Identifying the Root Causes

During 2021 and 2022, the researchers identified several differences in soil conditions in the inner rows compared to the outer rows that could explain the reduced stand, yield and bulb size. The inner row next to the tape experienced wetter and slightly colder soil conditions than the outer row. The inner row also had less soil compaction – and thus, poorer seed-soil contact, which is important for germination, Thornton said. “When we go through and put beds down in the spring, most of that soft soil is ending up in the middle, and then we’re shanking the drip tape in, which is breaking up the soil and making it less compact, too. It’s great for not having compaction, but it’s maybe not great for seed-soil contact. So that could explain why we’re having variable germination early in the season,” Thornton said. The researchers also found that the incidence of pink root was 22 percent


higher in the rows closer to the drip tape, and severity was 3 percent higher. Researchers believe that the wetter, cooler soil closer to the drip tape creates an environment more conducive to disease development, resulting in the lower yields and bulb size observed in the inner row.

the 2023 trial, they increased tape flow from 0.25 gpm/100ft to 0.34 gpm/100ft to allow for faster movement of the wetting front. This treatment tended to produce the highest bulb yields and 800 800

In 2023, researchers began evaluating ways to modify the soil conditions in the rows closer to the drip tape. To provide more uniform moisture across the planting bed, researchers evaluated drip tape emitter volume. They also applied pelleted bio-char over the seed row at planting to absorb sunlight and warm the inner rows and even out temperature fluctuations. To address soil compaction, they used a press wheel behind the planter to firm the soil and provide more uniform seed-soil contact. Finally, the research team examined the role of pink root by planting into a section of the field fumigated with chloropicrin and comparing it to nonfumigated ground in order to determine if the extent of stunting, stand loss, yield and bulb size reduction is related to the level of root disease. The increases in pink root, reduction in total yield and smaller bulb size for onions closest to the drip tape found in 2023 closely matched what researchers observed in 2021 and 2022. And while the soil warming and soil firming treatments did change the temperature and firmness of the soil around the seed during emergence and early plant growth, they failed to provide any improvement in stunting and yield loss for onions in the inner row. From these results, it does not seem likely that soil temperature and firmness are the main cause of the stunting observed, according to Thornton. Likewise, fumigation reduced pink root levels but did not reduce the difference in yield or bulb size between the inner and outer rows, indicating that pink root is probably not one of the main factors driving the stunting and reduced yields in inner rows. However, the researchers are interested in taking a closer look at the role of the drip tape emitter volume. In

minimize the difference between inner and outer row locations. Thornton recommends that this high-flow drip tape treatment be evaluated for at least one additional year to confirm the results.

JH Biotech • jhbiotech.com/chelation-and-mineral-nutrition Biomin

Biomin is a line of fully chelated plant nutrients resulting from the chelation of mineral nutrients with amino acids. These chelates protect the nutrient from combining with other elements or losing nutrient value for absorption. JH Biotech’s Biomin chelated line is OMRI, CDFA and WSDA organic certified and compatible with humic and fulvic acid products. Without using harsh chemicals, it provides plants with stable nutrients, balancing mineral deficiencies more quickly than conventional inorganic nutrients. It can be used for soil and foliar applications without compromising environmental quality and safety. Biomin may be applied to all crops and turf. It reduces the effects of saline soils, water deficiency and weather conditions while encouraging increased yield, homogeneous ripening, more flavored and high quality fruit, and greater nutrient absorption.

Nutri-Cal • nutri-cal.com Nutri-K

Nutri-K liquid potassium is a special formulation of highly soluble potassium, carboxylic acids and carbohydrates. The carboxylic acids and carbohydrates, which are the same complexing agents identified in the formulation of NutriCal, are derived from plant extracts in a patented process. There are no nitrates, chlorides or sulfates. It has a low salt index and is therefore non-corrosive. The product works when the T.O.G. complexes the elemental potassium ion, which subsequently allows the ion to be absorbed directly and immediately through the leaf and fruit cell walls. Nutri-K T.O.G / liquid potassium complex provides a unique delivery system, which protects the potassium from forming an insoluble compound, enabling more efficient movement of potassium ion to the fruit/vegetable where it is needed most.

Omex • omexusa.com Slyce

Slyce Ca8% provides organic compounds, feeding soil microbial activity, which increases the soil-available fertility, especially when applied after granular fertilizers (e.g., DAP, MAP, CalSul or KCl), by reacting with those granular nutrients to release their components for faster and more efficient fertilizer use by plants. In addition, Slyce aids in water penetration and increases the permeability of the soil profile, providing better soil moisture movement for developing bulbs.
