Dr. Gupta is an expert on tillage systems effects on mass (water and chemical) and energy fluxes in soil. His research experience include quantifying river bank erosion using Laser scanning; predicting residue cover from satellite imagery; antibiotic losses from manure applied fields; effect of antibiotic feeding in animals on increased antimicrobial resistance in the environment; impact of tillage system on transport of sediment, phosphorus, and herbicide in overland flow; tillage and manure interactions on surface and subsurface water quality from artificially drain fields; impact of winter waste application on nutrient losses; and the role of earthworms on preferential transport of water and contaminants in soil.
