Research Interests: 
Site-Specific nutrient management for cotton, wheat, sorghum, and camelina.  Energy balance of crop production for ethanol.  Spatial analysis of soil properties, canopy reflectance for in-season N management, variable-rate fertilization, N fertigation for surface, center-pivots and drip irrigation.  Soil profile nitrate testing.  Nitrogen cycling in soils, crop N use efficiency, 15N studies, N mineralization, denitrification, and nitrate leaching.  Carbon sequestration and soil quality. Water quality.  Ammonia volatilization.  Environmental contamination and impact from N fertilizers.  Greenhouse gas emissions from soils. 

International agriculture, especially central and west Asia.
