My research interest is to understand site-specific soil fertility, nutrient stratification and uptake dynamics, soil and tissue testing, crop sensing, soil management and environmental factors, and yield goals for improving nutrient management, increasing crop yield and profitability, and building resiliency in agriculture.

I have state-wide research and extension soil fertility responsibilities mainly for row crops such as corn, soybean, cotton, rice, and grain sorghum. I also help interpret soil-test results and provide fertilizer recommendations for horticulture crops. Some of my research responsibilities are to develop and/or update fertilizer recommendations, identify yield limiting factors, diagnose in-season nutrient deficiencies, develop best nutrient management practices, improve soil health, and reduce off-site fertilization impact by understanding site-specific soil fertility, nutrient stratification and uptake dynamics, soil and tissue testing, crop sensing, soil management and environmental factors, and yield goals. My routine extension responsibilities are to help producers, crop consultants, and extension agents understand soil sampling, testing, and interpretation of soil-test results, crop fertilization for maximizing crop yield and improving soil fertility based on different fertilization philosophies, tissue testing for diagnosing and correcting in-season nutritional deficiencies, 4R nutrient stewardship and adopting the best nutrient management practices, and building resiliency in agriculture.
