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.
