Research Projects
1. NMSU Initiative on Carbon Management and Soil HealthThe main goal of the NMSU initiative on carbon management and soil health in arid and semi-arid environments is to identify, verify and disseminate cost effective practices to soil health and carbon management in all major land use types, i.e., croplands, rangelands, forests, and urban lands. NMSU has the existing facilities to create living laboratories to identify, evaluate, and demonstrate the action steps. Four of our existing Agricultural Science Centers (ASCs) will serve as living laboratories, examining the viability and verifiability of C sequestration approaches for arid and semi-arid lands. In addition, off-campus ASCs across the state and on-campus crop, range, and turf-management sites will demonstrate C sequestration practices unique to those regions.
2. Soil Health Framework for Water-Limited regions
There is a growing consensus around a set of
soil health indicators that are repeatable, sensitive to management changes,
and include chemical, physical, and biological components. However, a framework
that links soil health indicators to essential soil functions and their
relative sensitivity to management decisions in water-limited environments is
yet to be identified. The overarching goal of this project is to develop that
framework under two major management factors, cropping systems intensification
and manure application, in water-limited environments. The project will
evaluate the relationships between soil health indicators and specific soil
functions, including a better mechanistic understanding of soil health and soil
water dynamics.
3. Conservation Systems in Drylands
Cropping systems that reduce or eliminate tillage and improve crop, soil, and water management strategies can enhance soil health and agricultural sustainability in the semiarid southwestern USA. We evaluate tillage systems, crop rotations, and other novel cropping strategies to improve soil health, reduce soil erosion, and mitigate greenhouse gas emissions from diverse crop rotations.
4. Cover Crops for Cropping System Diversification
Typical cropping systems in the western United States use intensive tillage and a long fallow period to conserve moisture for crop production. Cropping system diversification through cover crops and alternative crops could improve soil health, water conservation, and sustainable crop production. We are evaluating the effects of various cover crops on soil properties, water conservation, and soil microbial community structure in different crop and forage production systems.
5. Optimizing Water Use for Sustainable Food Systems
6. Soil Sustainability in Changing Climate
7. Forage Systems Project

8. Sustainable Farming Systems in Nepal
Sustainable crop production in Nepal is continuously challenged by environmental and economic pressures on farmers. We are working on research and demonstration projects that benefit farmers through improved soil management and integrated pest management practices on soil health and the agricultural sustainability of small-holder farming in Nepal.
