The purpose of the Air Management Practices Assessment Tool (AMPAT) is to provide an objective overview of mitigation practices best suited to address odor, emissions and dust at your livestock operation so that livestock and poultry producers may compare and narrow their options of mitigation techniques. Practices are divided into three categories by source: 1) Animal Housing; 2) Manure Storage & Handling; and 3) Land Application. Each mitigation practice has an individual page which includes a printable fact sheet and a short online slide presentation.
Ammonia: Ammonia is a colorless, pungent, nitrogenous gas. It volatilizes from a solid or liquid material when the ammonium ion is present and other physical conditions exist. Ammonia gas can react in the atmosphere with gaseous acidic species to form fine particulates (ammonium [NH4+] aerosols), which are a health concern. Atmospheric NH3 can be deposited during rain events and lead to soil acidification and increased concentrations of nitrogen in surface waters, potentially contributing to eutrophication.
Application: to reduce emission of odors and gases from the manure storage by altering the manure’s chemical or microbial properties
- Can be implemented with little change to current manure system.
- Typically little scientific information on performance of additives.
Application: used for during field application of manure to reduce odors and emissions
- Potential to reduce odors and emissions
- Injection and incorporation can conserve nutrients.
- Soil disturbance can potentially increase erosion.
- Requires more horsepower for injection or incorporation.
- Costs may be greater for injection versus broadcast applications.
