Biography
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.Dr. Mohammed’s research and Extension programs focus on three critical aspects of organic cropping systems: nutrition, soil health quality, and water management. Recognizing the unique challenges of farming in arid regions, his work integrates innovative technologies.
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 graduate and postdoctoral research focused on irrigation management and nitrogen management for various cropping systems across Nebraska.
