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:
- Phosphorus characterization of Alabama soils, development and evaluation of tools for environmental phosphorus loss risk assessment.
- 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.
- 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.
- Understanding the impacts of phosphorus stratification on yield in row crop systems.
- Quantifying nitrogen losses from row crop systems receiving animal manure using a field-scale nitrogen budget and crop simulation modeling.
- 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.
- Development of novel phosphorus extraction technology from poultry litter and synthesizing next-generation biofertilizers.
- Development of high fertilizer-grade poultry litter pellets.
