PI: Rajan Ghimire, Ph.D.
My research focuses on improving efficiency, profitability, and soil environmental quality in dryland and limited-irrigation cropping systems. I am interested in soil organic matter dynamics, nutrient cycling, soil-plant relations, and greenhouse gas emissions, soil organic matter-microbial community interactions, and their relationships with sustainable crop production and ecosystem services.
Postdoctoral Associate
Wooiklee Paye, Ph.D.Dr. Paye's research involves evaluating conservation tillage systems and exploring the potential of improving soil health and resilience through innovative crop and forage production practices in semiarid regions.
Graduate students
Sundar Sapkota, Ph.D. Student, 2021-2024: Effects of circular grass buffer strips on soil health and soil C/N cycling.

Vesh R. Thapa, Ph.D. Student, 2018-2021: Cover crop effects on soil biological health and crop production in limited irrigation cropping systems. Vesh is comparing soil health indicators such as mineralizable C, available N, soil aggregation, and crop yields with and without cover cropping.
Laboratory Technician
Sk. Musfiq-Us-Salehin, M.S. 2020: Evaluate soil N pools and N2O emissions in the dryland sorghum. More on his work is available here
