The science assessments of nutrient loss reduction strategies of multiple Midwestern states have concluded that cover crop inclusion is the most efficient adaptive soil management practice that can be employed to reduce the contribution of nitrogen (N) to the Gulf of Mexico. However, the adoption of cover crops on agriculture land in the Corn-Belt region remains minimal primarily due to questions that link to how cover crops affect crop yield, N availability and fate and economics. Thus, Dr. Armstrong’s presentation will expound upon experiments, where he is (i) determining the impact of cover crop inclusion on the soil distribution and availability of inorganic N within different N management systems; (ii) quantifying the cash crop yield responses to the addition of cover crops and N application timing; and (iii) evaluating the efficacy of both N application timing and cover crop inclusion on nitrate losses via tile drainage.

Dr Armstrong is an Assistant Professor of Soil Conservation and Management in the Department of Agronomy at Purdue University. He holds a B.S. degree in Plant and Soil Science from Southern University, a M.S. in Soil Fertility from Alabama A&M University, and a Ph.D. in Agronomy from Purdue University. The overarching objective of his research program is to determine the agronomic, environmental, and economic benefits of cover crop inclusion within conventional and alternative nitrogen management systems on multiple scales: plot, field, and watershed. The impact of Dr. Armstrong's research program has been recognized by several awards and numerous invited presentations to share his research findings with farmers, agricultural commodity groups, extension agents, and state/government soil conservation agents. Dr. Armstrong gains the greatest satisfaction as a professor when transferring knowledge to others from his research findings, and during the process of developing and training graduate students to be future soil scientists.
