Indiana CCA Conference 2020 Presentation
 
 

Cover crop adoption in the Midwest has significantly increased within the last decade. However, critical questions remain that relate to impacts of cover crop management on nitrogen availability, cash crop production, and water quality.  Therefore, this presentation will share results of Dr. Armstrong’s investigation of next generation cover crop management to increase crop production, while advancing water quality.

Speakers

Shalamar Armstrong

Purdue University
Biography

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 in-field nutrient and soil loss reduction practices within conventional and alternative cropping systems of 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, Dr. Armstrong’s 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.
