Manure management might help decrease GHG gas from animal agriculture.

Studies reported a reduction in CH4 emission (-35 to -99%) with aeration of cattle and pig slurry (Amon et al., 2006; Martinez et al., 2003). Amon et al. (2006) reported, however, an increase in N2O emission (by 144%) with aeration of cattle slurry (Table 6). The overall potential for loss of N as NH3 or denitrification products will be high during aeration, and N2O emissions as high as 19% of total N in pig slurry have been reported (Chadwick et al., 2011). Hence, measures to conserve N during aeration would be needed to ensure GHG mitigation via this treatment.
