Brief Project Summary:

One of the many agronomic benefits of cover crops is their ability to take up and store nutrients. Decomposing cover crop biomass then releases those nutrients in a plant-available form for future crops. This project fills gaps on information that describes the nutrient contribution of cover crops and the resulting impact on the following cash crops. It increases understanding of the relationships between cover crop biomass and nutrient recycling. Efforts quantify nutrient uptake and biomass production of cover crops at different planting dates, as well as measuring changes in soil nutrient levels. The trials used a cover crop mix of legumes, like crimson clover and hairy vetch, with tillage radish, a brassica.

Key Benefactors:
farmers, agronomists, Extension agents

Information And Results
Final Project Results

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
