Rajan Ghimire, Ph.D. 

Associate Professor and Principal Investigator

My research focuses on improving efficiency, profitability, and soil environmental quality in dryland and irrigation cropping systems. The primary area of my research involves soil organic matter dynamics, carbon and nutrient cycling in agroecosystems, greenhouse gas emissions, soil organic matter-microbial community interactions, and their relationships with sustainable crop production and ecosystem services. Contact me if you are interested in these research topics. More information about


Laboratory Members

Amrit Dhoj Adhikari
MS Student (ENMU)
Amrit's research involves studying soil/residue carbon mineralization kinetics in laboratory conditions and litter decomposition study in the field. He is a graduate student at Eastern New Mexico University and is engaged in my research group through ENMU-NMSU collaboration. 


Hamza Badrari
MS Student (EPPWS)
Hamza works on cover crop, compost, and tillage effects on weed dynamics in semi-arid dryland and limited irrigation cropping systems. 




Olufemi Adebayo
Ph.D. Student
Olufemi Adebayo is interested in soil health and soil-plant water dynamics. His research project evaluates cover crop and compost effects on soil health and soil-plant water dynamics in winter wheat - sorghum - fallow rotation.


Sundar Sapkota
Ph.D. Student
Sundar is interested in farming systems innovations for improving soil health and agroecosystem resilience. His project evaluates the effects of circular grass buffer strips on soil health and C/N cycling.
  




Pramod Acharya 
Ph.D. Student
Pramod is working on forage production systems. He investigates soil C cycling and sequestration potential, greenhouse gas emissions, and nitrogen transformation in forage production systems.
