UNIVERSITY PARK, Pa. — Planting cover crops in rotation between cash crops — widely agreed to be ecologically beneficial — is even more valuable than previously thought, according to a team of agronomists, entomologists, agroecologists, horticulturists and biogeochemists from Penn State’s College of Agricultural Sciences.
“As society places increasing demands on agricultural land beyond food production to include ecosystem services, we needed a new way to evaluate ‘success’ in agriculture,” said Jason Kaye, professor of biogeochemistry. “This research presents a framework for considering a suite of ecosystem services that could be derived from agricultural land, and how cover crops affect that suite of services.
“Cover cropping is one of the most rapidly growing soil and water conservation strategies in the Chesapeake Bay region and one we are really counting on for future improvements in water quality in the bay. Our analysis shows how the effort to improve water quality with cover crops will affect other ecosystem services that we expect from agricultural land.”
