Plant and Soil Sciences
The Department of Plant and Soil Sciences conducts research related to major agronomic crops, including cotton breeding and genetic improvements, row crops, soil microbiology and ecology, and the impact of environmental factors on plants and soils. Additional research is focused on new and existing herbicide and weed control management strategies in ornamental and row-cropping systems. Scientists also work in floriculture and ornamental horticulture, including landscape performance, production and propagation of nursery crops. Other scientists study management and eradication of aquatic and invasive weeds.
