PI: Rajan Ghimire, Ph.D.

Cropping Systems and Soil Management Laboratory

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



Pramod Acharya, Ph.D. Student, 2019-2022: Soil health and forage quality. The main goal of Pramod's research is to find a suitable mixture of cover crop in limited-irrigation corn-sorghum rotation that leads to crop diversity and improve soil resilience in forage production systems. 






Vesh R. Thapa, Ph.D. Student, 2018-2021: Soil health and crop production in limited irrigation cropping systems.  Vesh is comparing soil health indicators such as active C, mineralizable C, available N, soil aggregation, and crop yields in limited irrigation cropping systems with diverse cover crops.
