Abatement of Ammonia Emissions From Confined Animal Feeding Operations.

There is a need for manure management systems that can effectively address environmental concerns associated with ammonia emissions from confined animal feeding operations. Aside from dietary manipulation, several approaches have been evaluated for reducing ammonia emissions along some or all the components of typical manure management systems (production, collection, transfer, treatment, storage and utilization). These strategies include physical, chemical, and biological methods, especially in combination as part of total management systems that not only reduce the ammonia losses to the environment but also maximize the value of manure through energy production, nutrient recycling, and promote food safety and sustainability of animal production. This presentation includes research results on technologies developed in ARS Florence to reduce ammonia emissions along the production, collection, transfer, treatment, storage and utilization components of a swine manure treatment system.
