Biography

Dr. Sutie Xu's major research is soil health, carbon and nutrient cycling, water dynamics, greenhouse gas emissions and microbial activities in a variety of ecosystem types under different management and climate conditions. Her research relies on interdisciplinary studies to understand the influence of anthropogenic, environmental and biotic factors on ecosystem functions and the environment. The goal is to increase producer awareness of the importance of sustainable management in agroecosystems and motivate the adoption of
management strategies such as cover cropping, diversified crop rotation, livestock integration, organic farming and precision nutrient management.
