영문 초록

Atmospheric ammonia is a very important constituent of the environment because it is the dominant alkaline gaseous species present in the atmosphere. Ammonia is known to affect ecosystems at relatively low concentration. In this study flux profiles of ammonia emitted from the cattle housing were evaluated using a dynamic flux chamber (DFC). We have developed the emission factor of NH3 from the cattle housing. Analysis of ammonia flux variation was made with respect to such variables as manure surface temperature, pH, and ammonium concentration. Ammonia flux has been measured up to summer in 2007 at calf and cattle housing. In the fall, average ammonia flux from calf and cattle housing was estimated as 1.406 (±0.947) and 1.534 (±0.956) mg m−2 min−1, respectively. In the winter, average ammonia flux was estimated 1.060 (±0.569) from the calf housing and 1.216 (±0.655) mg m−2 min−1 from the cattle housing. The correlation coefficient (R=0.732) between ammonia flux and manure surface ammonium concentration exhibited stronger relationship than manure surface pH and temperature. In the fall, ammonia emission factor from calf and cattle housing was estimated as 3.94 (±2.66) and 11.41 (±5.86) kg-NH3 animal−1 yr−1, respectively. In the winter, ammonia average flux was estimated as 2.89 (±1.59) from the calf housing and 6.51 (±3.67) kg-NH3 animal−1 yr−1 from the cattle housing.
