Environmental Agronomy

Nutrient Cycling and Soil Health

My research group is focused on Environmental Agronomy. We study farming practices that meet producer goals, but that also reduce environmental impacts. By understanding how soil ecosystem services function in various cropping systems, our research helps inform the development of better management practices. Management practices of interest include: cropping system diversification, cover cropping and intercropping, conservation tillage, compost and amendments. Ultimately, we strive to provide the biogeochemical information that is needed to make progress towards designing regenerative agricultural systems

We are interested in the fundamental mechanisms that regulate nitrogen and carbon cycling, and the associated relationships to soil ecosystem services. We study: 1) soil health and fertility as influenced by cropping system management, 2) nutrient recycling, nutrient loss, and crop nutrient use efficiency, and 3) the edaphic and environmental factors regulating organic matter accumulation, loss, and stability. We measure soil health indicators, soil nitrogen transformations, nitrous oxide emissions, and crop nutrient use dynamics.
