Dr. Eric D. Billman is a Research Agronomist currently working on projects related to improving cotton management practices and water management for the southeastern U.S. With a background in forage and cover crop genetics, his research interests include incorporating novel cover cropping systems into cotton productions systems of the Southeast to enhance sustainability, as well as investigating the potential benefits and efficacy of newly developed row and cover crop germplasm adapted for drought and heat stress.
