Our research focus is to minimize non-point source pollution of phosphorus and nitrogen in agricultural systems. We utilize a systems approach to develop solutions for better utilization of animal manure and reduce their environmental footprints. Some of our ongoing research projects are:

    1. Phosphorus characterization of Alabama soils, development and evaluation of tools for environmental phosphorus loss risk assessment.
    2. Assessing the quality and quantity of agricultural runoff and phosphorus loss from the agricultural fields as a result of the adoption of cover crop and smart irrigation technologies through edge-of-field monitoring experiments.
    3. Understanding the distribution of soil phosphorus pools in manure impacted Alabama soil regions to guide the development of best management practices to reduce phosphorus losses.
    4. Understanding the impacts of phosphorus stratification on yield in row crop systems.
    5. Quantifying nitrogen losses from row crop systems receiving animal manure using a field-scale nitrogen budget and crop simulation modeling.
    6. Exploring the role of gypsum as a bedding material in poultry houses to reduce ammonia emissions and evaluating the suitability of gypsum amended litter for row crop production.
    7. Development of novel phosphorus extraction technology from poultry litter and synthesizing next-generation biofertilizers.
    8. Development of high fertilizer grade poultry litter pellets.
