Maria Bonita Villamil

Associate Professor

Dr. Villamil identifies management strategies to improve soil health and productivity in agroecosystems by addressing the societal challenge of sustainable food production. She focuses on how changes in soil health brought about by agronomic practices relate to carbon and nutrient cycling, crop production, and mitigation of greenhouse gas emissions.
