Cover Crop Research

Iowa Learning Farms has recieved several grants to research cover crops on farmer partner fields. The projects explore the benefits of cover crops on Iowa farmland using winter rye over five years and using cover crop mixes.
 
Partners for the projects include the Iowa Cover Crop Working Group, Practical Farmers of Iowa, Iowa Department of Agriculture and Land Stewardship State Soil Conservation Committee, Leopold Center for Sustainable Agriculture, USDA-Natural Resources Conservation Service and Iowa State University farmer association farms.
