Corn Following a Rye Cover Crop – Can We Make It Work?
Cereal rye cover crop use can be used as a management practice to limit soil nitrogen (N) loss, soil erosion, herbicide dependence, and improve overall soil structure and health. However, corn following a rye cover crop can often results in crop stress and yield loss due to spring depleted soil N, N immobilization, and poor emergence caused by the rye cover crop. This presentation will discuss research that provides insights into understanding how agronomic management and N fertilizer management can help limit corn stress and yield loss when following a rye cover crop.

Dan Quinn
Dr. Dan Quinn is currently an Assistant Professor of Agronomy and the Extension Corn Specialist at Purdue University. Dr. Quinn earned his B.S. and M.S. in Crop and Soil Science at Michigan State University and his Ph.D. in Plant and Soil Science at the University of Kentucky. His interdisciplinary research and extension program at Purdue works to improve the overall production, profitability, and environmental performance of Midwestern U.S. corn systems. Currently, Dr. Quinn’s research program includes studies examining yield physiology, agronomic management intensities, precision technologies, nutrient management, and cover crop use in corn production systems using large-scale and small-plot field research trials.
