Craig C. Sheaffer
Ph.D.: Maryland (1977)
Year Appointed: 1977
Areas of Interest
Alfalfa and forage management; sustainable cropping systems; director of sustainable agriculture graduate program.
Research is on perennial native and introduced legumes, grasses, and woody species. I study organic crops, crop rotations, legume management, cover cropping, and legume-grass forage polycultures. I teach 2 undergraduate courses and a graduate level course. I conduct the alfalfa variety trials and corn silage hybrid trials and participate in outreach education programs.
