Safe Management and Use of Manure, Biosolids, and Industrial Byproducts

Develop improved manure (swine lagoon effluent and poultry litter) application and management practices that reduce nutrient losses to the environment, increases utilization by crop plants, increase recycling of nutrients, and enhance soil quality. Determine and reduce bacterial pathogen levels in manured fields and assess impacts on soil fungal and bacterial ecology, including antibiotic resistance. Determine ammonia and greenhouse gas emissions from broiler houses and manured fields and develop management practices to reduce them. Evaluate the benefits and potential risks from possible new uses of manure and industrial byproducts (e.g. FGD gypsum).
