Animal Waste Management Research
Project Number: 6445-12630-001-00
Project Type:
Appropriated
Start Date: Jun 11, 2003
End Date: Aug 31, 2005
Objective:
Research objectives are to investigate, develop, and evaluate management practices and treatment technologies that protect water quality, reduce air emissions, and control pathogens at animal production facilities, manure storage areas, and field application sites. This research is curative, exploratory, and protective. Conduct solution-oriented research that aid farmers in solving problems associated with animal waste in an environmentally sound manner considering the unique problems associated with karst topography in Kentucky and elsewhere. Specifically, quantify the environmentally important nitrogen (N), phosphorus (P), and other elements fluxes and transformation in soil, water, and air as a result of long-term land application of animal manure. Quantify changes taking place in soil chemical, physical, and biological characteristics resulting from long-term application of animal manure. In the animal facilities, gas losses of nutrients which impact air quality and fertilizer value are modified through management and assessed for newer animal production systems. The potential for water pollution is measured for row crops and forage management, soil types and animal manure fertilization in watersheds for karst topography.
Approach:
Research approach will focus on the major manure management issues such as: excess nutrient of soil and water; atmospheric emissions of ammonia, particulates, volatile organic compounds (odor), hydrogen sulfide, and greenhouse gases; and pathogenic microorganisms and pharmaceutically active compounds. Specifically, determine the impacts of animal manure nutrient quality, quantity of application, and timing of application on row crops or forage productivity, on rates of nutrient removal in grain or harvested hay, on accumulation of excess nutrients in soil, and on nutrient mobility in the soil. Determine soil quality characteristics, nutrient speciation, mineralization rates, and soil nutrient balances and imbalances with long term fertilization with animal manure. Determine emissions from animal production operations; develop and test management practices for emissions reduction; develop process models to predict emissions, and develop tools to predict dispersion of emissions. Determine the water quality of runoff and subsurface water with animal manure applications to watersheds and pasture botanical changes with and without animal grazing on three soil types. With regard to pathogens research, detect pathogens in complex matrices; assess pathogen survival under a range of conditions; predict and control transport and dissemination; develop cost-effective treatment technologies; and assess risks associated with manure pathogens.
