Perennial Cover Crops Project Receives Grant Funding

A team of scientists at seven institutions, led by D. Raj Raman at Iowa State University, received a five-year, $10 million AFRI Sustainable Agricultural Systems grant from USDA National Institute of Food and Agriculture to study the potential benefits of using perennial grasses as cover crops. Annual cover crops require farmers to plant and harvest them every year, so researchers are investigating perennial ground covers that could provide environmental benefits and save farmers money. The scientists will work to identify and refine perennial covers that go dormant during the period when specific cash crops are growing and determine the best practices for using these cover crops without sacrificing crop yields.
