Tim Gottman’s 2,400-acre farm in northeast Missouri looks harvested, but among the remnants of corn stalks are blobs of green plants that are thriving despite the cold and windy conditions of late winter in the Midwest.
His land includes wide swaths that gently slope away from the road, and the water from a recent rain is pooling up in some places.
“All this water would be running that way, and if this green, the wheat and rye, weren't here, it would just allow the water to run faster and take the soil with it,” Gottman said. “And when the soil is leaving, your fertilizer's going with it.”
Gottman is a big fan of cover crops, and he says they are improving the bottom line on his corn and soybean farm. And he’s not alone.
The University of Illinois completed a study late last year using a combination of USDA reports and satellite images to produce the most accurate survey of cover crop usage in the Midwest. The study found that in the past 10 years, the number of acres with cover crops tripled — from 1.8% to 7.2%.
It’s a big jump but still a small number of acres.
“It is certainly not at a level that would be necessary for some of the challenges, like the water quality challenges like soil erosion,” said Jonathan Coppess, director of agriculture policy at the University of Illinois. “It's going to take a lot more acres to get there.”
Cover crops also received a temporary boost from COVID-19 relief money. The Biden administration spent $60 million on subsidies for more than 12 million acres of cover crops during the 2020-21 growing seasons.
While that funding was temporary, Coppess said it may set the stage for more sustained efforts to incentivize cover crops.
Coppess and other cover crop advocates hope that a big leap could come if more incentives are put in the farm bill, which is up for renewal this year. With all the benefits of cover crops — such as reducing fertilizer use and costs; increasing yields; limiting erosion and keeping carbon in the ground — Coppess said there could be more bipartisan support for incentives.
“It can maybe help jump-start that by showing, you know, funds going in for this practice will get response on the ground, and we can measure it,” he said.
The current farm bill expires in September, and incentives for cover crops will be a tiny sliver of what looks to be a more than a half-trillion-dollar package.
