Singh’s faculty appointment includes research and Extension responsibilities in applied soil science-agroecology and landscape position management. He serves as State Extension Specialist for landscape position management. His research is focused on spatial/temporal modeling of nutrient dynamics in the plant, soil, water, and gaseous phases ranging from plot scale to watershed scale. His program includes developing prescription models for landscape position-based research. His research also involves understanding the effects of management practices such as cover crops, tillage, and topography on crop yields, soil and water quality in row crop production systems. At the Northern Missouri Research, Extension and Education Center, his program emphasizes nutrient management for sustainable crop production that reduces the environmental effects of farming practices at the field and farm scale.
