ARG Cover Crop Seeded into 6-leaf Standing Corn!

In the cover crop revolution, there have been so many surprises…most have been pleasant…and yet, the surprises keep on coming.

When we started, it was a slam dunk that a cover crop on winter fields would reduce erosion. That was, however, only the tip of the iceberg.

  • Twenty years ago, people were surprised that annual ryegrass would survive a Midwest winter without constant snow cover.
  • Fifteen years ago, the surprise was how deep the roots of annual ryegrass sink into soil (sometimes more than 5 feet), through layers of compaction.
  • Farmers experimenting with annual ryegrass were more recently amazed about annual ryegrass’ ability to sequester N, thereby saving on fertilizer costs.
  • Initially, the “best” method of planting the cover crop was with a drill. Now we find a majority of farmers broadcasting seed from a plane or high clearance spreader.

So, perhaps it should come as no surprise that farmers in Quebec, Canada, have been seeing increased corn and soybean yields when planting annual ryegrass IN THE SPRING, when the corn is up but with only 3 – 6 leaves showing.

Doubters are now becoming believers, and expert cover croppers in the Midwest are being advised to try this out on limited acreage.

Check out this power point presentation from earlier this year, where results of three years of replicated trials in corn and soybean show some convincing evidence that a companion cover crop can actually boost production that same year.

Annual Ryegrass Sales Brisk on Production Gains in 2012

Sales of annual ryegrass seed this year have been “pretty good” said Illinois-based agronomist Ron Althoff. Even with extremely dry summer months, farmers were banking on enough rain to germinate annual ryegrass seed, while also hoping against a subsequent dry spell that could wither the new cover crop.

It’s a risk many are willing to take, after having seen the value of cover crops in the 2012 season, when corn and soybean production yields were 10 to 12 percent higher on acres where cover crops were used, according to a Midwest farm survey by the Sustainable Ag Research and Education program (SARE). Just that news has precipitated a continued rush to find cover crop seed. The research also indicated that the number of acres planted continues to climb steadily, increasing nearly one-third this year over last year.

Althoff, a seed dealer for Oregon-based Saddlebutte Ag, said that planting annual ryegrass has become more popular by airplane, or with high-clearance equipment, into a standing corn or soybean crop. Drilling cover crop seed after harvest gets trickier with a late harvest because annual ryegrass needs about 40 days of above freezing weather to establish well.

Althoff said that while he prefers annual ryegrass, farmers can plant other cover crops later because they need less time to establish.

“Corn grown on annual ryegrass cover crop got in some cases 50 bu. better yield than average,” he said. With that kind of return, it’s clear why people are finding the investment for cover crops worthwhile.

USDA cover crop campaign gets a boost

A USDA campaign endorsing cover crops is getting a boost in visibility from The Howard G. Buffett Foundation, a development that could pay dividends for Oregon seed producers.

The foundation decided this past spring to raise awareness of the two-year old USDA Natural Resources Conservation Service campaign titled Unlock the Secrets in the Soil.

An article recently released in an online publication provided information on the campaign and profiled two growers who use cover crops.

Leon Moses of Greensboro, N.C., said he began using ryegrass, hairy vetch and clover as cover crops in 2006.

“I began to learn very quickly that no-till and cover crops combined to make healthy soils that rewarded me with higher yields,” Moses is quoted as saying.

Jack Erisman of Illinois said he’s been using cover crops for many years. “The bottom line?” he said. “Cover crops offer a way to find true sustainability and real costs savings.”

The NRCS campaign is aimed at improving soil health by touting the benefits of cover crops, such as annual ryegrass, red clover, alfalfa and radish, crops with seed production in Oregon.

The campaign provides growers tools and knowledge about improving soil health through the use of cover crops.

The Howard B. Buffett Foundation works to improve food security for impoverished and marginalized populations by, among other means, improving the sustainability of food production.

With the Illinois Department of Agriculture recently starting a cover crop initiative and the NRCS campaign getting a boost in visibility, it is clear that cover crop seed production offers Oregon producers a growing market opportunity.

Cover Crops – Nothing Sells Like Success

Mike Plumer put in cover crop demonstration plots at the Farm Progress Show this year. Imagine, growing a test plot on the no-till Fairgrounds (Decatur, IL) in wheat mulch. Imagine planting a cover crop in the Spring and hoping to get enough moisture to show to people a good stand in August!

As an agricultural practice, it stinks. But as a educational tool, it was a great success.

“We had 18 field plots (20 x 40′) with all sorts of cover crops. Among them were annual ryegrass, crimson clover, cereal rye, vetch, oats and radish,” Plumer said. “We only got one-tenth of an inch of rain in the weeks running up to the Fair, but thankfully there was good sub-soil moisture.

Plumer said the reception by the public was extremely good. He said that the majority of attendees were not new to cover crops and that many came with very specific, sophisticated questions about cover crop varieties, seed mixtures, planting options and management techniques.

“Acceptance of cover crops has grown tremendously in the past few years,” he added. The Conservation Technology Information Center estimates an increase of 350% in just the past four years.

With corn and soybeans coming off the fields late this fall, more producers have resorted to aerial or broadcast seeding of cover crops into standing corn and soybeans. Click here for more information about that practice.

Annual Ryegrass Popular at Farm Progress Show

By MITCH LIES

Cover crops were center stage at the 2013 Farm Progress Show Aug. 27 – 29 in Decatur, IL. Prominent among them was annual ryegrass.

The emphasis on cover crops mirrors the skyrocketing interest in annual ryegrass and other cover crops by Midwest growers in recent years.

Agricultural consultant Mike Plumer, a retired University of Illinois Extension agent who has worked with cover crops for three decades, estimated that cover crop usage has grown 400 percent in the last two years, alone.

At the 2013 Farm Progress Show, cover crops for the first time were featured in a crop demonstration plot. The exhibit provided growers a first-hand look at different cover crops, like millet, radish, crimson clover, cereal rye, buckwheat, rapeseed, turnips, oats, winter peas and annual ryegrass.

Annual ryegrass has become one of the most well known cover crops in the past 15 years, Plumer said. He estimates that annual ryegrass represents 25 percent of the total cover crop usage in the Midwest.

“My yields have been climbing every year, particularly after the third year,” said Rich Recker, a Mt. Pleasant, Mich., grower who has used cover crops for six years. “The third year is the charm.”

A survey of 750 growers conducted last fall by the Conservation Technology Information Center and the USDA North Central Region Sustainable Agriculture Research and Education program showed that corn planted after cover crops had a 9.6 percent increase in yield, compared to corn planted next to it that didn’t follow a cover crop.

Soybean yields increased 11.6 percent following cover crops.

In the hardest hit drought areas of the Corn Belt, yield differences were even greater, according to the survey, with an 11 percent increase in corn yields and a 14.3 percent increase in soybean yields following cover crops.

The survey showed a 350 percent jump in the total acreage in cover crops between 2008 and 2012.

Joe Rothermel, of Champaign County, Ill., said he’s seen improved soil health since he started using annual ryegrass as a cover crop four years ago. The improved soil health has helped get water to plants, he said, particularly in drought years.

“I think we’ve got to do everything we can to get water into the ground, and keep it there,” Rothermel said.

Rothermel also said he’s getting weed control from the cover crop, a side benefit he never expected when he started using annual ryegrass.

“We don’t have near the marestail pressure,” he said.

Macon,IL., grower Paul Butler said he, too, has been getting weed-control from his annual ryegrass cover crop. He’s also been happy with the ryegrass’s ability to break up compaction.

“When we have compaction issues, there is not a lot I can do,” he said. “The radish and the ryegrass seem to be doing a good job with that.”

Butler said he flies on the annual ryegrass seed before corn is harvested. Doing so gives the annual ryegrass added time to establish  before a killing frost.

John Gullidge, a farmer from Lewisville, Ill., said annual ryegrass is helping tie up nutrients in what he describes as poor soil and put them into a form the next crop can use.

“I’m trying to make the best of what I have with what I can,” he said.

Crop consultant Mark Mellbye, a former Oregon State University Extension agent, has been working with Oregon ryegrass seed growers on developing the Midwest cover crop market since the effort began in 1996.

Overall usage of annual ryegrass in the Midwest has increased from a few thousand pounds in the late 1990s, to maybe 5 million pounds three or four years ago, Mellbye said, and up to 15 or 20 million pounds this year.

The interest in annual ryegrass, Mellbye added, has skyrocketed just between last year and this year.

Planting Annual Ryegrass as a Cover Crop

In most places in the Midwest, August and early September are the ideal times to plant your cover crop. Many are using aerial application while corn and soybeans are still in the field. Drilling is still preferred in some parts, however, because the seed-to-soil contact is better and, thus, you can put out fewer pounds of seed per acre.

Crop Yield Gains with Cover Crops

SARE (Sustainable Ag Research & Education) released a study of cover crop useage over the past 5 years. Read below, proof positive of the value in both crop yield and soil health. Best yet, the results are those reported by farmers themselves, based on what’s been happening on their farms.

A summary is below…you can find the whole report here: http://www.northcentralsare.org/CoverCropsSurvey

Key findings included the following:

  • During the fall of 2012, corn planted after cover crops had a 9.6% increase in yield compared to side-by-side fields with no cover crops.  Likewise, soybean yields were improved 11.6% following cover crops.
  • In the hardest hit drought areas of the Corn Belt, yield differences were even larger, with an 11.0% yield increase for corn and a 14.3% increase for soybeans.
  • Surveyed farmers are rapidly increasing acreage of cover crops used, with an average of 303 acres of cover crops per farm planted in 2012 and farmers intending to plant an average of 421 acres of cover crops in 2013.  Total acreage of cover crops among farmers surveyed increased 350% from 2008 to 2012.
  • Farmers identified improved soil health as a key overall benefit from cover crops.  Reduction in soil compaction, improved nutrient management, and reduced soil erosion were other key benefits cited for cover crops.  As one of the surveyed farmers commented, “Cover crops are just part of a systems approach that builds a healthy soil, higher yields, and cleaner water.”
  • Farmers are willing to pay an average (median) amount of $25 per acre for cover crop seed and an additional $15 per acre for establishment costs (either for their own cost of planting or to hire a contractor to do the seeding of the cover crop).
