New publication listing herbicide adjuvants now available from Purdue

The 2016 “Compendium of Herbicide Adjuvants” is available from Purdue Extension through Purdue’s The Education Store.

Now in its 13th edition, the publication lists 779 products from 38 companies. Each listing contains the product name, principal functioning agents, use rates, special comments and name of the manufacturer or distributor. The first edition, published in 1992, contained 76 listings from 22 companies.

An adjuvant is any substance added to an herbicide to increase its effectiveness or make it easier to apply. A combination of factors account for the popularity of herbicide adjuvants over the past several decades, said Bryan Young, professor of weed science and editor of the publication.

“Foliar herbicide applications continue to be a critical part of weed management and growers must optimize herbicide efficacy to minimize the risk of herbicide failure that favors the selection of herbicide-resistant weeds,” he said. “In addition, significant advancements and innovations in herbicide adjuvant chemistry have evolved that allow for the combination of multiple adjuvant chemistries into a single multi-functional product.”

The purpose of the Compendium is to provide a format that allows for a comparison of adjuvant products that fall within or across the different adjuvant categories, Young said.

Testing soil solution to gain insights into the 4Rs

In terms of the Right Rate component of the 4Rs, the folks at AgroLiquid are taking a novel approach to finding it through research and unique method of monitoring the fertility in the liquid between the soil particles.

Using a series of syringes attached to tubing placed at varying depths beneath the soil, the soil solution underground can be carefully extracted. The nutrient levels in the solution can then be compared to nutrient application rates to get a handle on what the plants are using and what is being lost.

“We have developed this method of how to test nutrients in soil solutions to see how much is lost. What we are doing has the potential to change how the industry approaches fertility and the loss of nutrients,” said Nick Bancroft, vice president of AgroLiquid. “We test the nutrient solution to see what nutrients are moving in the soil and compare that to what was applied and see what amount was used and what amount was lost.

NBB pushing for tax incentive extension

This fall the National Biodiesel Board sent a letter to House and Senate tax committee leaders urging extension of the biodiesel tax incentive before it expires on Dec. 31. The letter was sent on behalf of U.S. biodiesel producers nationwide.

“We strongly urge you to extend the biodiesel tax credit and take this opportunity to make a simple, common-sense reform by focusing the credit on U.S. production,” said Donnell Rehagen, Interim NBB CEO in the letter. “Legislation pending before Congress — S. 3188 and H.R. 5240 — would accomplish these objectives by extending the incentive through 2019 and changing it from a blender’s credit to a domestic producer’s credit. The legislation has strong support from American biodiesel producers and strong bipartisan support in both the House and Senate — reflected last year when a similar proposal passed the Senate Finance Committee.”

The growth of the U.S. biodiesel industry in recent years is paying tremendous dividends in reducing emissions, strengthening our energy security, generating competition in the diesel sector and creating jobs and economic activity in every state in the nation.

The challenges and rewards of growing buckwheat in Ohio

Like many farms in Ohio, the 2016 planting season started a little later than expected for Marion County’s Lill Farms. Planters started rolling on May 23 and wrapped up in the first part of June. Summer dealt a rough five-week period with no rain and then timely August rains helped push yield numbers to higher marks than anticipated.

As harvest time approached, Lill Farms’ David Niederhuber had to take a hiatus from the corn and soybean fields  to take off another crop that is part of the farm’s rotation — buckwheat.

“We started growing buckwheat here in the early 1990s and it certainly is a unique crop,” Niederhuber said. “It’s a double-crop with a short growing season and it goes in after wheat and this year we planted it on July 15 but it can go in as late as Aug. 1.”

With a mid-summer planting time frame and a short growing season window, the weather experienced this year was ideal for the unique crop.

The certified crop advisor

The Certified Crop Adviser (CCA) and Certified Professional Agronomist (CPAg) programs of the American Society of Agronomy are the benchmarks of professionalism. The CCA certification was established in 1992 to provide a benchmark for practicing agronomy professionals in the United States and Canada. The Ohio CCA program has been operating since 1994; a local board directs our program and is managed by the Ohio AgriBusiness Association: http://oaba.net/aws/OABA/pt/sp/cca.

Certification is the standard by which professionals are judged. The purpose of a certification program is to protect the public and the profession. It is a voluntary professional enhancement to a person’s career credentials. Farmers and employers prefer to work with Certified Crop Advisers because they have demonstrated they have the commitment, education, expertise, and experience to make a difference in a client’s business.

 

Who should be certified?

Any adviser/consultant that spends the majority of their time advising growers or farm managers/operators on agronomic practices and can meet the standards of the program.

Ohio’s Crop Progress — November 14th, 2016

Tillage and fall spraying activities are underway with most grain harvest complete, according to Cheryl Turner, Ohio State Statistician with the USDA’s National Agricultural Statistics Service. There were 6.3 days available for fieldwork for the week ending November 13. Winter Wheat and cover crops are progressing well with the benefit of above normal temperatures and adequate soil moisture. Moisture levels of corn harvested during the week decreased one percentage point to 17 percent.

Developing a strategy for precision soil sampling

There are many different tools and approaches available that, if used correctly, can help to improve your nutrient management (variable rate application, precision placement, crop sensing via NDVI, late-season application, nutrient BMPs, etc). However, selecting the correct tools and using them to your advantage is not always an easy process, since the best tool and the best approach can vary by farmer and field. The key to a successful soil fertility program is to identify your goals and develop a plan to meet those goals each season. Identifying both short and long term goals make it possible to develop a strategy to use precision technologies to systematically improve your soil fertility program. Some goals you may consider are:

1.     Improve mapping of field variation that affects soil fertility

2.     Maximize the economic return of fertilizer applications

3.     Reduce off-site movement of nutrients

 

Selecting A Soil Sampling Approach

One of the most important decisions that you will make as part of your fertility program is how to divide (the area within a field boundary) a field into representative areas and what the area represents yield soil type etc.

Late season rains thwart disaster for many Ohio crop farms in 2016

Thank God for the rains in August — farmers in Ohio who have not done this yet, should consider doing so promptly. Those incredibly valuable rains in mid- to late-August were the thin thread saving many fields from a total yield disaster.

By early August nearly all of Ohio was suffering from varying degrees of hot and dry conditions. On the week ending Aug. 7, the growing degree day accumulation was well ahead of normal for nearly every location in Ohio monitored by the U.S. Department of Agriculture National Agricultural Statistics Service, with locations in eastern Ohio leading the charge. New Philadelphia was plus 574 GDDs and Cambridge had a whopping 653 GDDs more than normal. As temperatures soared, rainfall really dropped off. The Aug. 7 NASS report reflected this trend clearly with nearly every Ohio location in a rainfall deficit compared to normal. Sydney was over nine inches of rain behind and Ashtabula was at 9.99 inches below normal, according to NASS.

Ohio soybean farmers celebrate winning two 2016 R&D 100 Awards

Two technologies developed through Ohio Soybean Council (OSC) and soybean checkoff collaborations have won 2016 R&D 100 Awards. Both technologies, Soy-PK Resin and Bio-YIELD bioreactor, leverage the natural properties of soybeans to increase the sustainability and improve health in modern industries. Winners were announced late last week at the R&D 100 Awards Conference in Washington, D.C.

“I can’t fully express how honored we feel as an organization to win R&D 100 Awards for our research and development efforts,” said Nathan Eckel, OSC Research Committee chair and soybean farmer from Wood County. “Research and development for soy-based products has been a priority for our organization for decades and we are proud to see our technologies recognized both nationally and internationally.”

Since the early 1990s, OSC has engaged in public and private collaborations that encourage rapid commercialization of new commercial and industrial uses of soybeans. For over 50 years, the R&D 100 Awards — dubbed the “Oscars of Invention” — is the place where the research and development community come together each year to recognize the top technology innovations around the world.

Green stems still a problem in soybeans

In many areas of the eastern Corn Belt, soybean growers had difficulties this harvest due to Green stem syndrome. When green stem syndrome occurs, stems and leaves can remain green after pods have matured. As a result, while pods and seeds are mature and dry enough to be harvested, harvest operations can be slowed as combines work to “chew” though green stems and leaves. In addition to creating harvest delays, green stem syndrome can increase fuel consumption and result in shattering losses if growers delay harvest until stems have fully matured.

The occurrence of green stems varies from year-to-year and can be affected by several factors, such as:

• Viral infections

• Insect feeding

• Late planting

• Drought stress

• Application of fungicides

Successful management of green stem syndrome requires management practices that include timely planting, establishing adequate plant stands, irrigation, and controlling insects/pests. Although green stem syndrome slows down harvest, soybeans should be harvested as soon as pods are fully mature in order to minimize harvest losses due to shattering.

Grower organizations encourage manufacturers to implement AgGateway’s ADAPT for precision ag

A dozen leading U.S. grower organizations are hailing the collaborative efforts that led to the new AgGateway ADAPT framework for interoperability in precision ag systems – citing the many benefits to farmers, and are calling on Farm Management Information System (FMIS) companies to formally commit to integrating the ADAPT framework into their systems in the near future.

The support was expressed in a letter this month to AgGateway Chairman David Black from the American Farm Bureau Federation, American Soybean Association, National Association of Wheat Growers, National Barley Growers Association, National Corn Growers Association, National Cotton Council, National Farmers Union, National Sorghum Producers, National Sunflower Association, U.S. Canola Association, U.S. Dry Bean Council, and USA Rice.

“Over the last decade, the most consistent concern raised by farmers using precision ag is that ‘different systems won’t work together,'” the letter states. “The farm and commodity groups are pleased that AgGateway member companies worked collectively to solve this problem by creating ADAPT….

Ohio’s Crop Progress — November 7th, 2016

Rain slowed down some of the farming activities but warm sunny days afterwards made harvest and some tillage possible, according to Cheryl Turner, Ohio State Statistician with the USDA’s National Agricultural Statistics Service. There were 5.7 days available for fieldwork for the week ending November 6th. Corn harvest is progressing but many fields remain with high grain moisture levels. Fields with mold and re-sprouting issues continued to be observed. Some soybean growers are looking for frosts to help with soft ground and green stems. Winter Wheat seedings are almost complete and condition is rated at 84 percent good to excellent, compared to 65 percent last year, when topsoil moisture shortages were more of a factor. Moisture levels of grain harvested over the week averaged 18 percent for corn and 12 percent for soybeans.

The election and the grain markets

After 18 months of build up that included rallies, debates and excessive political advertising, Election Day is finally near. Many were eyeing the polls through all of the rhetoric, accusations and spin, but after a new President is elected, on lookers will still have something to watch — the markets.

“I’ve been doing this since 1995 and I have never seen two candidates that wanted to take such a hard look at trade policy,” said Mike Zuzolo of Global Commodity Analytics. “I don’t think the dollar and currency markets are going to like that very much no matter the outcome at the polls.”

After months of not messing with interest rates, the Federal Reserve will have a decision to make under a new administration.

“Based on who wins, traders are wondering if the Federal Reserve will feel compelled and even pressured to keep quantitative easing in place and keep the dollar and deflation elevation as a result,” Zuzolo said.

Process turns wheat flour into CO2-capturing micropores

Researchers have shown how a process for the “carbonization” of wheat flour creates numerous tiny pores that capture carbon dioxide, representing a potential renewable technology to reduce the industrial emission of carbon dioxide into the atmosphere.

“With increasing carbon dioxide emissions, global warming is accelerating, accompanied by abnormal climate changes,” said Vilas Pol, an associate professor in Purdue University’s School of Chemical Engineering and the School of Materials Engineering. “It is imperative to develop efficient methods for capturing carbon dioxide.”

Purdue researchers developed a process that creates carbon compartments from wheat flour. Collaborating with researchers at Korea University in Seoul, South Korea, they studied carbon dioxide capture in these unique carbon compartments. The chemical compound potassium hydroxide was used to “activate” — or generate many small pores — in the wheat flour inside a furnace at 700 degrees Celsius.

The carbon dioxide is “adsorbed,” or bound to the material’s surface inside the micropores.

It takes many steps to find the right rate

Galen Koepke farms in Ottawa County on the banks of the Portage River just a few miles from Lake Erie.

A television crew was at Koepke’s farm within a few hours after the news broke after the Toledo water crisis in 2014. Since then, all agriculture in the watershed has been the subject of great water quality scrutiny, but Koepke is under a microscope.

In many ways, though, Koepke welcomes the attention because he knows he is doing things right according to the 4Rs with his farming practices. This has not always been easy, however, particularly for one 34-acre field that borders the Portage River. For many years, he had farmed and carefully managed the 20-acre field and then around 20 years ago he purchased a neighboring 14-acre field and combined them.

“On that 14 acres they had two large layer operations with a total of around 100,000 chickens and they had spread all the manure on that field for many years.

Agriculture still watching (and waiting for) WRDA

New research by the University of Tennessee quantifies what many in agriculture have known for years; failure of our aging river locks and dams along the Mississippi River and its tributaries would be ruinous with billions of dollars in lost jobs and reduced economic activity.

Recently, USDA released estimates of the economic implications to the agriculture sector should a disruption occur at either Lock & Dam 25 on the Upper Mississippi or La Grange Lock & Dam on the Illinois River waterway. The locations were selected because they are representative of the lock system as a whole but also because they occupy key locations on the river system.

“These are both 600 foot locks even though modern tows are 1,200 feet-long. They are also at the lower reaches of the waterways,” said Ken Hartman, chair of the National Corn Growers Association’s Market Access Action Team. “The southbound traffic here already contributes to long delays because of the lock size.

Ohio corn testing positive for vomitoxin

An increasing number of reports are coming in of corn testing positive for vomitoxin, with levels as high as six to 10 parts per million in some cases. Some of these numbers are taking producers by surprise.

Although the weather has been favorable for ear rot development, and consequently, grain contamination with vomitoxin, test results could be misleading in some cases, and may even be incorrect. Since there is not much that can be done about grain contaminated with mycotoxins, you should at least check to make sure that you got a fair test. Get a second opinion if needed.

There are several things about the mycotoxin testing process that could lead to inaccurate results, including how samples are drawn and handled. Remember, the number of ears infected within a field and the number of kernels infected on a given ear are highly variable. As a result, moldy grain and vomitoxin levels vary considerably within the grain lot.

Soybeans, China, and the rest of the world: Changing of the guard?

Strong import demand is largely credited with soybean’s relatively high current price, especially in the face of a U.S. soybean yield that currently is a record by 3.4 bushels per acre. China remains the largest source of growth in world soybean imports measured in bushels, but its projected growth rate for the 2016 crop year is smaller than the growth rate for the rest of the world. If this projection holds, it will be the first time China has not had a higher growth rate since it became a continuous soybean importer in the mid-1990s.

This study begins with the 1995 crop year and ends with the current projections for the 2016 crop year. Since 1995, China has been a net importer of soybeans.

 

Perspective

Over the past 20 years, China’s annual imports of soybeans exploded from essentially zero to 3.2 billion bushels currently projected for the 2016 crop year.

Ohio’s Crop Progress — October 31st, 2016

Soybean Harvest Slowly Wrapping Up

Rains were relatively light but the effects of a wet fall persisted, according to Cheryl Turner, Ohio State Statistician with the USDA’s National Agricultural Statistics Service. There were 5 days available for fieldwork for the week ending October 30. Light showers kept harvest of corn and soybeans to a slow pace. Green stalks along with muddy fields were the main obstacles to finishing soybean harvest. Some frosts were noted, but more will be needed to firm up the ground and kill stalks. Cover crops and wheat benefited from the elevation in temperature and soil moisture. Moisture levels of grain harvested over the week averaged 19 percent for corn and 13 percent for soybeans.

Autumn observations of 2016 crops

We are just compiling the Extension fall soybean weed surveys; it is bad again with marestail and giant ragweed leading. The big news this year is that resistant marestail is statewide — the whole state now looks like the southwest has for the past 10 years. OSU Weed Specialist Mark Loux says to better manage resistant marestail:

  • Do spray a fall treatment for next years no-till soybeans.
  • Keep it simple. Don’t bother with a residual in the fall, save those dollars for the spring application.
  • Timing that generally works well is late October into early November. Although I like to wait until after we have had a rain to settle the corn stalks and spruce up the weeds a little.

Fall soybean insects

They are getting worse. Maybe it was the dry fall or the wet August, or just a shift in insects but as I was harvesting I saw more seed damage than I have ever seen before.
