Spotlight on Agustín Nuñez
Ph.D. Student
Department of Soil and Crop Sciences

Agustín’s current research focus is soil quality changes during the transition from irrigated to dryland cropping systems in the Ogallala Aquifer Region. Due to declining levels of available water, conversion from irrigated to dryland cropping systems is increasing in some areas of the Ogallala Aquifer Region, one of the most important aquifers in the world. In general, irrigated cropping systems yield more and have more soil organic carbon than dryland cropping systems. However, little is known about the evolution of soil quality after conversion from irrigation to dryland and the effect of soil quality on crop production during this transition. Results will help to understand the interaction between water management, soil health and crop production and identify the best cropping system management practices to improve water use efficiency.
