Abstract

A 3year study was conducted to determine the effects of anaerobic digestion AD large particle solids and manure additive More Than Manure MTM™ on ammonia NH3 and greenhouse gas GHG carbon dioxide nitrous oxide and methane emissions when raw and treated manure were surfaceapplied The presence of large particle solids resulted in greater NH3 emissions probably due to reduced infiltration of liquid manure into soil P  005 Anaerobic digestion did not have a consistent effect on NH3 emission Manure with greater ammoniacal nitrogen AN concentrations had significantly greater NH3 loss after manure application P  005 Anaerobic digestion of manure also did not have a significant effect on GHG flux P  005 Raw manure with large particle solids had significantly greater CO2 flux than the other raw manure treatments on the day of manure application P  005 There was no significant manure treatment effects P  02 on methane flux over the 3day period after manure application The manure additive MTM™ did not have significant effects P  005 on NH3 and GHG fluxes The results of this study suggest that solids and AN concentrations in manure are the most important factors affecting NH3 emissions after surface application
