As fall cover crops go into the ground, many farmers have questions about how to best manage cover crops and achieve benefits such as soil health and nitrate retention. Mike Castellano will share his research on how cover crops can best be managed to maximize benefits during Iowa Learning Farms’ monthly webinar on Wednesday, September 21. Castellano is the William T. Frankenberger professor of soil science and an associate professor in the department of agronomy at Iowa State University.

The webinar is free for you to tune-in, and all that is needed to participate is a computer with Internet access.

Cover crop webinar to focus on soil health and nitrate retention


“Future gains in crop production and environmental quality will require a systems approach that integrates many disciplines,” Castellano says. To achieve this vision, Castellano uses expertise in soil science and ecosystem ecology to work with a broad range of scientists, managers and policymakers. He has a PhD in soil science from Pennsylvania State University.
