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.
