CRWP’s cover crops program is being funded by a recent Demonstration Grant from the Minnesota Department of Agriculture.
The cover crops shown below were planted on June 6, 2016 and all photos were taken in the same field in Goodhue County on July 27. After the corn is harvested, this annual rye and red clover mix will grow steadily until frost. It will hopefully stay green under the snow, keeping the soil in place throughout the winter and early spring.
Our Agriculture Program Consultants, Lee Thompson and Gene Kuntz, are available to consult with farmers about cover crops. Contact CRWP to learn about our current programs.

What are cover crops?
These resilient plants are planted between cash crop seasons to keep living cover on the landscape. In our area, they are normally established in the fall;. This keeps the soil covered for the 5 – 7 months after the fall harvest and before the next spring planting of crops.
What are the benefits?
- Helping protect water quality by reducing erosion and trapping excess nitrogen. This keeps it from leaching into groundwater or running off into surface water.
- Increasing organic matter in the soil and improving overall soil health by adding living roots to the soil during more months of the year.
- Providing livestock producers with additional grazing or haying opportunities.
- Providing winter food and cover for birds and other wildlife. During the growing season, cover crops can provide food for pollinators.
CRWP is partnering with farmers to help them experiment with incorporating cover crops into their operations. In 2016, CRWP is partnering with 18 farmers on 950 acres of cover crops. And in 2015, CRWP partnered with 15 farmers on 710 acres of cover crops. If you or someone you know is interested in trying out cover crops, please contact us.
