New Year, New Cover Crop for You?

Some may have formed this New Year’s resolution back in the summer: to give annual ryegrass a try as a cover crop.

As stated by many experts, don’t start too big with something you have little experience with. Cover crops are like driving on the highway, using a rifle for hunting game or playing full-tilt in a new sport – you run a better chance of success if you put your sights low the first year. Here are some tips:

Talk to others about their experience with annual ryegrass cover crops. Preferably, talk to a neighbor, who has similar soil condidtions
Research your local options for cover crop seed. Ask questions to find out whether your seed dealer is more interested in sales or in conservation tillage
Buy a variety of seed that has a track record for success. Specifically, you’ll want a variety that has been used in your area, and one that has shown hardiness for withstanding winter weather.
Plant a small parcel the first year, perhaps 10 acres or a bit more
Commit to keeping a very close eye on all details of the process: soil type and condition planting date, weather data during the time the cover crop is growing and inputs like nitrogen.

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.

Slake Test Demonstrates Cover Crop’s “Sponge” Qualities…and Bio-health

Ray Makenzie of Marcellus, Michigan, found himself with a thousand acres of highly erodible land when he switched from raising outdoor hogs to a confinement system in 1996. He went to no-till and foresees cover crops next year because of a farm demonstration he just attended.

“I am really excited about cover crops and have to get on this for next year,” he said. “I worry about where the land is leading to with our current practices. At the rate we are going, we are not going to leave the next generation with much healthy dirt.”

Hans Kok, a partner in the Indiana-based Conservation Cropping System Initiative, spoke on the benefits of cover crops and demonstrated one aspect with the “Slake Test.” ,Side by side soil samples were submerged in water. One sample was tilled soil while the other had not been tilled for several years. The tilled soil crumbled away and disintegrated in the soaking, leaving a murky sediment at the bottom of the beaker.

A second demonstration simulated a 2-inch rainfall over a one-hour period using spray bottles to soak no-till versus tilled soil samples. The tilled sample had runoff containing a high percentage of soil in the collection vessel while the no-tilled soil held together, absorbing the rain like a sponge and leaving only trace amounts of soil runoff in collection containers. Ironically, the soil samples for both demonstrations were taken from fields that were only forty feet apart, so soil type differences were negligent.

A new cooperative effort through the conservation districts in Van Buren, Berrien and Cass counties offered growers the opportunity to aerial seed annual rye grass into standing corn or soybeans at a cost of $32.50 per acre in 2013. Additional farmers who were not members of the cooperative joined the effort, resulting in a total of 1,600 acres seeded on Aug. 28 in the three counties, according to Colleen Forestieri, conservation technician for the Van Buren Conservation District. “Our goal next year is to triple that number to 3,000 acres,” she said.

Cover Crop Acreage Tops 2 Million Acres in Midwest?

In 2005 there were not many cover crops being planted in the Midwest. Although annual ryegrass had very positive results, management was seen as somewhat complex and there was limited adoption.

Here it is, almost 9 years later, and the cover crop phenomenon continues to impress us all. It’s hard to calculate exactly, but crop consultant and cover crop advocate Dan Towery estimated that upwards of 2 million acres of cover crops were planted last year in the Midwest.

But here’s the astonishing thing. Key players in cover crop development will meet in Omaha in February, 2014. It’s by invite only. And among the agenda items, according to Towery, is to strategize how to increase the acreage in Midwest cover crops by TEN FOLD in the next decade – to 20,000.000 acres! That sounds like a lot until you understand that there over 170 million acres of corn and soybean acreage in the Midwest, according to the Dept. of Agricultural and Consumer Economics at the Univ. of Illinois Urbana – Champaign.

One of Towery’s concerns: even to get to the 20 million acre mark, it may be a challenge to find the seed to plant those acres. Seed farmers in Oregon have increased their acres to match demand of annual ryegrass and other cover crops. But are there enough acres to produce seed for a 10 fold increase? Stay tuned.

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.

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.

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).

Tracking N Loss in Midwest – Look at Cover Crops!

Studying the retention of inorganic N after last year’s drought was revealing. An Illinois team of researchers determined from 151 samples statewide that an average equivalent of 140 lb of N per acre was left over from 2012! (More than half was resident in the top foot of soil while the rest was in the second foot.)

Click here to read the whole article in No-Till Farmer.

The study also looked at how much of that N was being lost this spring and found that between 20 – 50 lb/ac had been lost. The researchers speculate that some may be below the two-foot depth but said that with spring rains, drain tiles were showing dramatic increases of nitrates.

What the article didn’t mention is that annual ryegrass and other cover crops are superb crops to soak up that N available in the soil.
