Free 'Recipes' Tell Farmers How to Start Growing Cover Crops
Nebraska Ag Connection - 11/08/2019
Farmers who want to start growing cover crops can turn to "recipes" on the Midwest Cover Crops Council website.
Free downloadable PDFs tell how and why to add cover crops into a corn-soybean rotation, says Charles Ellis, University of Missouri Extension field specialist in agricultural engineering. Ellis serves on the council's advisory board.
The site has recipes for Missouri, Illinois, Indiana, Iowa, Michigan, Minnesota, Nebraska and North Dakota. Download the publications at mccc.msu.edu/getting-started/cover-crop-recipes(opens in new window).
"Planting a cover crop ahead of a soybean cash crop is often the easiest way to introduce cover crops into your rotation," Ellis says.
One of the Missouri recipes, MU Extension publication MX81, looks at cereal rye, which proves to be a good choice before soybean because typical fall conditions in Missouri provide a suitable planting window for that cover crop, he says. But Ellis discourages cereal rye before corn for beginning cover crop growers because it requires changes in corn nitrogen management and other adjustments.
Instead, the council suggests a two-way mix of oats and radishes for spring termination or a two-way mix of oats and crimson clover for better erosion control and living roots in the spring before corn. MU Extension publication MX82(opens in new window) details how to do this.
The cover crop recipe guides tell how to plan for cover crops, choose corn and soybean hybrids, and purchase seed. They also explain crop sensitivity to selected hybrids and effects of residual herbicides. The simple three-page guides tell what field work must be done in fall and spring for best results and provide details such as seeding rates and nutrient applications.
In addition to step-by-step suggestions, the guides offer links to resources. Ellis and Rob Myers, MU adjunct associate professor of plant sciences, and other MU faculty and MCCC council members contributed to the guides.
McKnight Foundation funded the project.
