Research Project: Development of Practices to Reduce Nutrient Losses to the Environment from Land Application of Animal Waste and By-products

Location: Soil Dynamics Research

Project Number: 6010-11120-008-22-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Jul 1, 2019
End Date: Jun 30, 2024

Objective:
Develop management practices for economically and environmentally sustainable full life-cycle poultry production systems.

Approach:
Research will be focused on poultry waste management to ensure the economic and environmental sustainability of poultry production in Alabama and beyond. Specific areas planned for study include: developing technologies to extract and recover Phosphorus (P) from poultry litter; refining the Alabama phosphorus index tool to accurately assign the phosphorus loss risk of manure application practices in agricultural lands; development of best management practices to reduce the transport of phosphorus, nitrogen and greenhouse gases from agricultural fields receiving poultry litter; and utilizing gypsum as a bedding material in poultry houses to improve bird performance and control NH3 emissions from the litter.
