Corn Yield Gap Reduction Strategies for Cover Crop Systems
Cover crop adoption in the state of Indiana has reach a plateau in recent years, primarily due to barriers related to negative tradeoffs associated with adoption cost and reduction in corn yield. To advance cover crop adoption before corn, Drs. Armstrong and Quin will team up to present “Corn Yield Gap Reduction Strategies for Cover Crop Systems”. These strategies will demonstrate effective yield protection adaptive management ranging from precision planting cover crops, the inclusion of overwintering legumes, and nitrogen fertilizer rates and timing.
Speakers

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.

Shalamar Armstrong
Dr. Armstrong is an Environmental Soil Scientist and Associate professor in the Department of Agronomy at Purdue University. His research program investigates the agronomic, environmental, and economic impacts of current and emerging regenerative agricultural practices that reduce nutrient and soil loss and promote carbon farming in the Upper Mississippi River Basin. Dr. Armstrong’s research is executed on multiple scales ranging from the soil microbiome to the evaluation of conservation practices on field and watershed scales. Annually, his applied research program advances the knowledge of the agricultural and farming community on cropping systems management that facilitates nutrient loss reduction, nutrient cycling, and competitive crop productivity.
