System Summary

Ammonia emissions data from open-lot and hybrid (combination of free-stalls and open-lots) dairies in the milder climate of southwest US indicated that summer emissions from these facilities were nearly 50% higher than winter emissions. Due to their large surface areas, lagoons …

Air Emissions After Manure Land Application Including Subsurface Application of Poultry Litter and Solid Manure

When manure is land applied there are many different gases emitted, including greenhouse gases and those that contribute to odors. How much is emitted and how does that change with different application methods? This presentation was originally broadcast on September 18, 2009. More…
