Biography and Research Information

OverviewAI-generated summary

Sandhya Karki investigates greenhouse gas emissions from agricultural systems, with a particular focus on methane and nitrous oxide. Her research examines the impact of various management practices, including cover cropping, irrigation strategies, and conservation tillage, on emission rates in crops such as rice and cotton. Karki has published work exploring seasonal and multiyear emissions, analyzing data related to biomass, nitrogen content, and soil composition under different agricultural conditions. Her scholarship also includes studies on the effects of biochar and cover crops on soil physical properties. Karki has collaborated with researchers from Arkansas State University and the University of Arkansas at Fayetteville on shared publications. Her work contributes to understanding the environmental footprint of agricultural practices.
