Cover Crop Resources

“Rye takes up leftover nitrogen in fall and winter, then slowly releases it back into the system, and moisture conservation from cover crops is really good during short, dry periods,” notes Andy Clark. He earned a PhD in agronomy and has technical oversight for all publications produced by SARE, the Sustainable Agriculture Research and Education Program.

Yet rye is only one of many crops suitable for cover in given situations. Clark recommends several cover crop information resources accessible in whole or part on the Web. The primary one is SARE’s own book on the subject.

Cover crops are valuable on a big scale as well as on individual farms, notes Alan Sundermeier, an Extension educator in Wood County, Ohio, who works with SARE.

“In this Great Lakes region, we’re under the gun to clean up phosphorus and nitrates by using cover crops,” Sundermeier says. “Water quality issues are not going away.”
