The focus of this study is to quantify ammonia emissions from typical manure management practices on conventional, organic, and grazing dairy farms in Wisconsin. Quantifying emissions for different dairy systems can help identify where management practices could be used to reduce ammonia losses specific to that system. Results presented per excreted manure show that the largest contributors to ammonia emissions include manure storage of all types, with solid storage having higher emissions than slurry or liquid. Application of solid, liquid, and slurry manure also results in large ammonia emissions, and all are comparable in intensity (6 pages; 2022).
