Lewis A. Gaston

Dr. Lewis A. Gaston is a Professor in the School of Plant, Environmental and Soil Sciences at Louisiana State University's College of Agriculture. His research focuses on soil chemistry, environmental impacts of agricultural practices, and sustainable land management. He earned his B.A. in Chemistry (LSU, 1977), M.S. in Agronomy (LSU, 1982), and Ph.D. in Soil Science (University of Florida, 1987).

His work examines soil management effects on water quality, nutrient cycling, and pesticide fate. Notable contributions include studies on phosphorus runoff mitigation, poultry litter utilization, and biomass grass potential in Louisiana's coastal plains. He teaches Soil Science and Advanced Soil Chemistry courses, receiving multiple Gamma Sigma Delta Teaching Merit Awards.

Publications span soil-chemical processes, environmental resilience, and agricultural sustainability. Key themes include phytoremediation, poultry waste management, and sustainable sugarcane practices. His research bridges practical solutions like hay harvest for soil phosphorus reduction with broader environmental resilience strategies.

Awards highlight his teaching excellence. Collaborative efforts include LSU AgCenter initiatives and interdisciplinary projects on biomass grasses. His labs explore soil-plant interactions and innovative land-use solutions for Louisiana's unique ecosystems.
