DEPARTMENT OF PLANT AND SOIL SCIENCES


We have excellent teaching, research, and outreach programs in the areas of plant biology (cellular, genetics, genomics, microbial, molecular and physiology), agronomy (including pathology, soil management and weed science), horticulture (sustainable landscapes, fruits and vegetables), landscape architecture and environmental soil sciences (biogeochemistry, hydrology and plant-soil interactions). We have a distinguished faculty, known nationally and internationally for their research and outreach, and within UD for their excellence in teaching, advising and mentoring students.
