Cover Crops in Grazing Systems

cover crop winter pea, clover, cereal ryeNoble Foundation researchers are studying how cover crops could be part of a year-round grazing system that provides economic and environmental benefits to farmers and ranchers. Noble Foundation research agronomist James Rogers, Ph.D., received a three-year conservation innovation grant from the U.S. Department of Agriculture Natural Resources Conservation Service to conduct the research. The grant will support Rogers in determining how much moisture is used and/or conserved by summer cover crops and how those crops impact production of grasses and legumes consumed by livestock (commonly called forages) during the winter months. Moisture is a key  component of crop and forage production. Sufficient moisture levels boost pasture quantity and provide benefits to soil, which ultimately helps farmers and ranchers. “We need to determine whether the cover crops take moisture away from or preserve moisture for winter pasture,” Rogers said. “Preserving moisture will allow for earlier fall production. However, if the cover crops use up the moisture, winter pasture production is limited.”
