Mineralization is an important biological process for conversion of organic nitrogen (N) to inorganic N which can be used by plants directly. To investigate the effect of different manures on soil mineralization, the soil amended with cattle (CtM), goat (GM), chicken manure (ChM) and pig slurry (PS) were incubated under in vitro condition and ammonium N ($NH_4{^+}-N$), ammonification rate and ammonia emission were determined for eighty-four days. $NH_4{^+}-N$ was the highest in PS-amended soil for the whole experimental period. $NH_4{^+}-N$ in PS-amended soil was gradually decreased until day 84, whereas it was rapidly decreased for the first 14 days and then slightly increased until 84 days in ChM-, CtM- and GM-amended soil. The ammonification rate showed negative value for the first 14 days in all treatments. From day 14, ammonification rate started to increase in CtM- and ChM-amended soil, whereas it was maintained in GM- and PS-amended soil until day 84. The daily ammonia emission was the highest in PS-amended soil ($41mg\;kg^{-1}d^{-1}$), followed by CtM-, ChM-, and GM-amended soil at day 1. It was gradually decreased until day 84 in all treatments. The total $NH_3$ emission was the highest in PS-amended soil with $0.6mg\;kg^{-1}$ for 84 days, while less than $0.1mg\;kg^{-1}$ in three other plots. These results indicate that different manures showed different soil ammonification rate and $NH_3$ emission.
