SARE Ties with DuPont-Pioneer on Cover Crops

In February, a select group of 300 cover crop experts gathered in Omaha to discuss the prospect of massively enlarging the number of cover crop acres in the Midwest.

At present, there’s an estimated 2,000,000 to 3,000,000 acres of corn and soybean cropland now being improved with cover crops each year. The meeting’s purpose – to explore how to expand that number to 20 million acres in the next six years.

Annual Ryegrass at Commodity Classic – Feb 28

Annual ryegrass is among the most popular cover crops. As such, it will be among the key elements in a Cover Crop learning session at the Commodity Classic this year, in San Antonio, TX. The session will cover both the trend in cover crop use nationally, but also specifics on how to make cover crops work for your acreage.

The Conservation Technology Information Center and DuPont Pioneer are sponsoring the session. Here’s a link to a full story and details about attending

The learning center session, “Cover Your Assets: Improve Productivity, Efficiency and Soil with Cover Crops,” will take place Feb. 28 at 1:45 p.m. in the Henry B. Gonzalez Convention Center, Room 217BC.

The presenters include Mike Plumer and Jamie Scott, both of whom have been long time annual ryegrass advocates. Mike worked for decades for the U. of IL as an Extension Educator. Jamie is an Indiana farmer, whose business now includes providing annual ryegrass seed flown onto about 60,000 acres each year.

Additional experts are Rob Myers, regional director of extension programs for the U.S. Department of Agriculture’s North Central Sustainable Agriculture Research and Education (SARE) program and Karen Scanlon, CTIC executive director, who will moderate the session.

“Cover crops are an exciting topic that continues to gain the spotlight,” Scanlon said.

Annual Ryegrass Seeded into Springtime Corn!

Yes, you read correctly…farmers in Quebec, Canada began experimenting, 5 years ago, with spring seeding annual ryegrass into new corn…when the plants showed between 4 and 6 leaves.

Apparently, the annual ryegrass goes dormant when the corn canopy closes over in June, leaving the grass in shade until harvest. After harvest, sunlight sets the annual ryegrass growing again like gangbusters. According to a new article in Corn Guide, the grass soaks up residual N, P, and K going into winter. The author reports, also, that even in early years, farmers see a bump in corn production from the addition of annual ryegrass. See the full article here.

Cover Crop Learning Opportunities this Winter

In February, in Omaha, a cover crop symposium is attracting cover crop innovators, big seed dealers, seed growers and equipment company reps to discuss how to quickly grow the cover crop usage.

Cover crops are now planted on approximately 2 million acres in the Midwest. One of the symposium’s central topic is how to turn that number into 20 million acres in the next couple of decades, or sooner.

The daylong symposium will be telecast live to 200 sites around the US, in hopes that a much larger audience can access the information.

On Feb. 6, Dan Towery will present on soil health and cover crops to the Ontario Soil and Crop Improvement Association in Brodhagen, west of Toronto.

In March, Dan and Hans Kok will present a 2 hour webinar sponsored by the Environmental Protection Agency. Their presentation is on how cover crops can impact water quality…largely by keeping soil and nutrients in the fields, less susceptible to erosion. Soil biology can influence yields, Towery said, and cover crops are a key contributor.

Cover Crop Veterans Increase Acreage of Annual Ryegrass in Midwest Corn and Beans

Nick Bowers looked at sales of cover crop seed from his Oregon farm this year and declared “we’re up from last year but the growth has leveled off a bit, compared to previous years.”

“The good news of cover crops has encouraged newcomers to try planting them,” he said. “But with adverse weather in the Midwest, corn and beans came off the field 2 – 3 weeks late this year. That means getting a cover crop on before cold weather was more of a risk, and I think that’s what held newcomers off somewhat,” he theorized.

Bowers has witnessed the phenomenal growth in sales of annual ryegrass and other cover crops as an Oregon grower. Before he and his partner began direct sales to the Midwest, he was involved in years of on-farm research as a member of the Oregon Ryegrass Seed Growers Commission. It was the Commission’s early and consistent cover crop education and promotion that helped to launch the current boom in cover crop use, he said. During those years, he and other Oregon grass seed growers donated tons of seed and thousands of hours of their time, working with cooperating farmers in Illinois and Indiana, to find out how cover crops could positively impact corn and bean production there.

“Those more accustomed to planting cover crops weren’t phased by the late harvest this year,” he continued. “They applied the seed – most often by plane – into standing corn and beans, then hoped that rain would take care of the rest.”

Based on contact with his Midwest customers, Bowers said that it appears that annual ryegrass and other cover crops are doing well, even with the weather not being ideal.

He said that while Indiana and Illinois have been leaders in cover crop adoption, other Midwest states are coming along quickly. In January, his partner will be at the Iowa Cover Crop Clinic, in Des Moines, Jan. 27 – 30, in conjunction with the annual Power Show, scheduled for the 28^th – 31^st.

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.

New Annual Ryegrass Management Guide for 2014

A new, comprehensive management guide for planting Oregon annual ryegrass as a Midwest cover crop is available now. CLICK HERE for a pdf download.

Updated from last year, this guide includes new information about seeding rates, tips on best control methods, including how to control it when also planting winter wheat. Plus, there’s information for using annual ryegrass as a forage crop,

Seeding Rate for Annual Ryegrass Cover Crop Varies

In past years, we’ve published pretty standardized rates for seeding annual ryegrass into corn and soybeans. The rates vary from about 12 llb/ac (drilling) to 25 lb/ac if broadcast or aerial seeding. Click here to go to our four-page management guide or here for our handy Quick guide.

Now, even among experts, there’s some thought to lowering the recommended seeding rate, in order to save money but also to make it easier to manage the ryegrass in the field.

Mike Plumer has seen instances where annual ryegrass was too heavy, creating difficulty drilling into it after burndown. The root mat of annual ryegrass, if too dense, can complicate the closing of the seed trench. Further, he says that annual ryegrass roots seem to go deeper if the stand is thinner, because the plants don’t have as much competition with each other. He’s seen effective stands at as low as 8 lb/ac and thinks the 25 lb/ac is too heavy.

Dan Towery is more cautious about cutting back on the recommended seeding rate. While he agreed with Mike that certain growing conditions would warrant less seed/ac, he doesn’t want to end up with stands that are too thin. He said that the 2012/2013 cover crop season was unusual in that annual ryegrass did super well. The reasons: lots of residual N in the field from last year’s drought, September rain that got the ryegrass established well and a long spring that prolonged the cover crop season.

The consensus decision, after more discussion, will manifest in a modification of language in our brochures. Stay tuned…but it looks like growers will be advised to use best practices for your area and the climate conditions. That means asking the experts, whether at your seed supplier, your Extention agronomist….or your neighbor who’s been growing successful cover crops and can guide you on the local recommendations.

And then again, you can always contact us…we’ll put you in touch with Mike or Dan – or any number of other successful cover crop growers in your area – and you can hear it directly from them..
