Iowa NRCS Profiles Annual Ryegrass Cover Crop Innovator

Cover Crop Club Learning to Manage Practice Together

by Laura Greiner, State Public Affairs Specialist, USDA/NRCS – Iowa

Trying something new and innovative is always easier when you can learn from someone else’s experience. For a small group of innovative Pottawattamie County farmers experimenting with cover crops, that someone else is Pete Hobson.

Hobson, a 20-year no-till veteran, said he turned to cover crops as a tool to build more organic matter after test results showed his organic matter had plateaued. “Ideally I would like to increase organic matter one percent every 10 years. I went with rye grass because it will root much deeper than wheat or cereal rye and is a better organic matter builder,” he said.

He aerial seeded his rye at the end of this August at a rate of 25 pounds per acre. “I was surprised with how little rain we had in September that it even germed,” Hobson said.

Looking at a mat of green under his corn stalk residue he asked, “ If we can do this well in a dry year, how well can we do in a normal year?”

Cover Crops, Annual Ryegrass, Popular No-Till Conference Topics

At the recent National No-Till Conference (NNTC) in St. Louis, MO, cover crops seemed to be on nearly everyone’s minds. Record numbers of attendees (900+….350 of which were 1st timers) saw dozens of presentations and informal “round table” discussions where cover cropping was featured.

Ray McCormick, the No-Till Innovator award-winner from last year, talked about his novel cover crop seeding technique….attaching a Gandy Orbit Air seeder to his combine! The Vincennes, IN, farmer uses annual ryegrass.

“Most popular speaker award” winner from last year, Jamie Scott, was again at the NNTC and talked about seeding annual ryegrass on more than 30,000 acres near his farm in Pierceton, IN. He and his father act as brokers for the seeding service, contracting with air operators to apply the seed before harvest.

Terry Taylor, Geff, IL, won the No-Till Innovator award this year, and he talked about the value of cover crop mixes, including annual ryegrass, crimson clover and oilseed radish. Jamie Scott says he thinks the annual ryegrass and clover mix is mutually beneficial, as the clover has tons of nitrogen and annual ryegrass is a scavenger of N.

Ohio crop consultant Joe Nestor spoke about the value of cover crops in getting into the field early in the spring. Where acres were covered in cover crops, snow melt occurred two days ahead of nearby frozen ground. The cover crops contribute to more worm activity and soil biology…and that’s why snow melts off it sooner.
