Expertise:
- Soil fertility
- Nutrient management
My research program in soil fertility and nutrient management emphasizes applied field experiments to develop efficient, cost effective, and environmentally sound nutrient management practices for agronomic crop production in Kansas. Areas of interest include the efficient use of fertilizers, soil test interpretations and fertilizer recommendations, and land application of manure and biosolids with emphasis on crop-available nitrogen. My program also assesses environmental risks associated with nutrient management and tillage.
