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.






Pramod Acharya,
 Ph.D. Student, 2019-2022: 
Soil C cycling and greenhouse gas emissions in forage systems. The main goal of Pramod's research is to find a suitable mixture of cover crop in the irrigated corn-sorghum rotation that leads to crop diversity and improve soil resilience. 







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.
