Summary

    The authors evaluated the emission rate of ammonia from swine manure(CA) Which was varied by water content. The emitted volume of ammonia from swine manure was measured aaer exposed to air at temperatures 20oC, 30oC and 40oC. CA was evaluated from the ratio between this measurement and evaluated ammonia volume when substitute CA=1 for equation in summary of previous paper.
    As a result, CA is correlated to water content of swine manure and environmental temperature. As the emitted ammonia volume in swine house was possible to estimate from using mass transfer coefficient of ammonia from swine manureand CA.

Keywords: swine manure, emission rate, volume of emitted ammonia
