Dr. Mohammed earned his Master of Science in Mechanized Systems Management and his Ph.D. in Agricultural and Biological Systems Engineering from the University of Nebraska-Lincoln. His research focused on evaluating irrigation and nitrogen management strategies across center pivot, subsurface drip, and furrow irrigation systems, with an emphasis on maize evapotranspiration, crop water productivity, soil-water dynamics, and physiological responses such as stomatal resistance. This work contributed to advancements in precision agriculture and limited irrigation management.
He gained expertise in the strategic implementation of cutting-edge technologies designed to enhance smart-precision irrigation and nitrogen management. These include the adept utilization of wireless sensor networks, AI-driven CropCAM imaging sensors, Eddy Covariance, and the Bowen Ratio Energy Balance System. These systems play a crucial role in measuring greenhouse gas fluxes between ecosystems and the atmosphere, aiding in the understanding of carbon and water cycles.
Dr. Ali Mohammed is an Assistant Professor and Extension Specialist in the School of Plant Sciences at the University of Arizona, based at the Yuma Agricultural Center. His work focuses on advancing sustainable organic agricultural practices in arid desert regions and holds statewide responsibility for Extension and research programs. Dr. Mohammed's research interest is in comparing different specialty and row crop systems, both organic and conventional cropping systems, in the lower deserts of the Southwest USA. His research and Extension programs focus on coupled irrigation and nutrition management, soil amendments, and improving soil physical properties. Recognizing the unique challenges of farming in arid regions, his work integrates innovative sensor technologies to enhance water and nutrient resource efficiency and sustainability.
