Iowa

The AgronomyHorticulture, Plant Pathology, and Agricultural and Biosystems Engineering Departments at Iowa State University and the USDA-ARS National Laboratory for Agriculture and the Environment conduct research and outreach focused on cover crops. Cover crop research projects address their effectiveness in improving soil and water quality, cover crop effects on weeds, diseases, and pests, and the agronomic aspects of incorporating cover crops into cropping systems in Iowa. Other field and greenhouse studies are evaluating different potential cover crop species and their impact on soil microbial ecology.


Cover Crop Recipes
