Program Areas: Agronomic Crops; Animal Sciences & Forages; Commercial Horticulture; Poultry
Specialty Areas: Nutrient management and environmental stewardship
I conduct applied research in areas of:
- Whole farm nitrogen (N) and phosphorus (P) balance.
- Development of best management practices for nutrients (N and P) in crop and animal systems aimed to protect the water, soil and air quality.
- Variable rate manure and fertilizer (N and P) prescription technology for crops.
- Manure mineralization and 4Rs (right rate, right source, right time and right placement).
- Greenhouse gas, ammonia and volatile organic compounds (VOC) reduction from animal-crop systems.
- Climate change and climate smart agriculture through use of existing animal and crop models such as IFSM, DSSAT, APSIM.
- Decision support tools to increase the resiliency of beef and poultry production systems in response to climate change.
My research and extension program focus area is environmental nutrient management. We are studying nitrogen and phosphorus cycling and transport from poultry litter impacted soils and also developing best management practices and tools to reduce the nitrogen and phosphorus footprints in the environment using a systems approach. We are also working on developing technologies to recover nutrient from manure using novel physio-chemical approaches. Other programing areas include nutrient budgets, P-index, phosphorus loss risk assessment tools, decision support tools for better agronomic production systems, and producers’ education and outreach.
