Soil Conservation and Management
Curriculum VitaeBiography
Dr. Shalamar Armstrong is an Associate 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.
