Abstract
Ammonia (NH3) emitted after land application and during manure storage not only lowers the fertilizer value of manure, it also causes public concerns to environment health. Greenhouse gases (GHG) emission from land application of manure can contribute to climate change. A three-year study was conducted to study the effect of anaerobic digestion (AD), large particle solids, and a manure additive MTMTM on NH3 and GHG (carbon dioxide, nitrous oxide, and methane) volatilization when dairy manure was surface applied. In addition, the effect of AD, large particle solids, and the manure additive MTMTM were evaluated for their effect on NH3 emission from dairy manure during 110 d storage. During the land application study, large particle solids had a significant effect on NH3 emission, resulting in greater NH3 emission due to the reduced infiltration of liquid manure into soil. Anaerobic digestion did not have a consistent effect on NH3 emission. Regardless of AD, manure with greater ammoniacal nitrogen (AN) concentrations had significantly greater NH3 loss. The manure additive MTMTM did not have a significant effect on NH3 and GHG fluxes. Generally, there was no significant treatment effect on GHG flux over the three-day period after manure application. In the manure storage experiment, the AN concentration in manure played an important role in NH3 emission. During the first 11 weeks of storage, AD manure had significantly greater NH3 emissions when compared to raw manure treatments. After the 11 th week and until the end of storage, there was no significant difference in NH3 emissions across the v manure treatments. The presence of large particle solids on the manure surface resulted in significantly lesser NH3 emissions when data was evaluated for the whole storage period. In addition, the manure additive MTMTM did not have a significant effect on NH3 emission during storage. The results of these two studies suggest that AN and solids concentrations in manure are the most important factors regulating NH3 emissions after land application and during storage
