A major challenge of the US dairy industry is to optimize milk production and profits while minimizing the environmental impact of animal manure. The overall goal of this project is to develop management practices and decision aids for operating a sustainable whole-farm dairy to handle manure in a profitable and efficient manner while avoiding detrimental effects on soil, water and air quality. This goal will be accomplished through a comprehensive integration of research, technology transfer and product/service development. Areas covered by the specific objectives include the following: (1) development of improved methods for estimation of manure nitrogen, mineralization and ammonia volatilization for nutrient management in the barn and field; (2) composting for dairy manure management; (3) diet manipulation to increase nutrient recovery and reduce nuisance odors from manure and (4) development of management practices to reduce nutrient and pathogen flow to surface and ground water. Research results will be incorporated into Decision Support Modules, tested, refined and disseminated to farmers and rural communities. This Project will be conducted by a multidisciplinary team of partners from USDA-Agricultural Research Service in Beltsville, MD, University research and extension (Cornell, Maryland, Penn State, Vermont), NRCS, the Northeast Dairy Herd Improvement Association, the Rodale Institute, NRAES and the Composting Council.
