Research Interests
- Field evaluation of conservation cropping systems/cover crops to improve soil health and sustainability
- Assessment of short-term soil health indicators for their ability to predict long-term improvements in soil healthand sustainability
- Evaluation of macro- and micro-nutrient fertility recommendations for row-crop production systems in Alabama
Many soils across Alabama can be considered unhealthy due to severe erosion, low organic matter content, and intensive farming practices historically used in the state. Soil conservation practices (i.e., cover cropping, conservation tillage) and appropriate fertility management have potential to improve soil health, reduce erosion, and increase water-/nutrient-use efficiency in Alabama row-crop production systems. My extension programs is focused on providing information to Alabama producers related to: 1) conservation management practices to improve the long-term soil health, 2) current and accurate recommendations for soil fertility management, and 3) best management practices to increase fertilizer use efficiency.
