The Iowa Learning Farms and the Iowa Organic Association have asked Dr. Kathleen Delate to present research conducted at Iowa State University about how soil health and water quality is improved through organic production systems by using longer crop rotations than conventional corn-soybean rotations. Small grains and perennial legume species, like alfalfa, are integral to supporting greater soil microbial populations and aggregate stability. Slower-release forms of nitrogen, required in certified organic production, are associated with less nitrate loading and greater water quality.
Dr. Delate is a Professor of Organic Agriculture in the Departments of Agronomy and Horticulture at Iowa State University where she is responsible for research, extension and teaching in organic agriculture.
