Key Issues:
Cover crops, No-till, Wheat

Mike Buis

Martinsville, Indiana

Type of Operation:
Mike, with his brother Jeff, farms 3,100 acres. Most of the cropland is in a corn-soybean or corn-soybean-wheat rotation.

View on Soil Health:
Conservation Compliance provisions require Mike, who grow crops on highly erodible land (HEL), to use conservation practices to be eligible for federal programs such as disaster assistance, conservation programs, or crop insurance premium subsidies. Although he is not required to do so, he’s added cover crops to his HEL land to ensure he is going above and beyond to minimize soil erosion.

Reason for Joining Soil Health Partnership:
He began working with the Soil Health Partnership in 2016 to experiment with cover crops.

Trials Partnered with SHP on:
Mike broadcasts wheat cover crop seed at approximately 60 pounds per acre with a fall fertilizer application (immediately after harvest) and incorporates both with a vertical tillage tool. Wheat is not harvested, so he terminates the wheat cover crop in the spring when it is approximately 12-14″ tall by burning it down with an herbicide application. Because there is no spring tillage, he plants directly into the cover crop residue with a no-till planter.

His trial is featured in the Benefits of Cover Crops Business Case.

Other Soil Health Practices Being Implemented:

Mike has about 1/3 of his acres in no-till and 1/3 in minimal tillage. He also expanded the acres he plants cover crops beyond his SHP research field.

Advantages Experienced Using New Soil Health Practices:
The biggest benefit of the wheat cover crop, in Mike’s experience, is that he uses fewer herbicides during the growing season. He estimates the value of this weed control benefit to be worth at least $10/acre. Also, although he is not required to add cover crops to his HEL, doing so ensures he is going above and beyond to minimize soil erosion–and significant increases in soil organic matter on Mike’s research field between 2016 and 2018 suggest that Mike might see long-term benefits in soil water holding capacity and nutrient cycling and availability as a result of using cover crops.

Implementing cover crops on his HEL was a natural fit for Mike after he started experimenting with cover crops on his SHP research field. Because he had already adopted minimum-till on his HEL in order to meet conservation compliance requirements, there was no additional cost, other than the seed itself, to seed or terminate the cover crop. Putting a dollar value on weed control has encouraged Mike to increase the use of cover crops.
