A 10-year field-scale study on the effects of winter rye cover crops on corn and soybean yields showed no significant impacts on cash crop yields attributable to cover crop use. The study by Iowa Learning Farms and Practical Farmers of Iowa was supported by state funders and the Leopold Center for Sustainable Agriculture.
In the article, "Leopold Center Helping Iowa," in Wallace's Farmer, Dec. 20, 2019, LCSA Director Mark Rasmussen discusses current activities of the center and ongoing work to fulfill its mission.
New research shows integrated organic crop and livestock production systems can conform to food safety standards. In-kind support from the Leopold Center provided student assistance for the research, led by Kathleen Delate, professor of horticulture and agronomy at Iowa State, and Angela Shaw, associate professor of food science and huan nutrition at ISU.
Findings of LCSA-supported research on the "eﬀect of social cohesion and social networks on perceptions of food availability among low-income consumers" are published in the "Journal of Business Research" January 2020 issue, by Priyanka Jayashankara, assistant adjunct professor in Iowa State's Ivy College of Business and the Seed Science Center, and Sekar Raj, chair of the Ivy College of Business Department of Marketing.
