Ammonia (NH₃) has been used as a target gas for nuisance complaints to restrict or close poultry operations near encroaching rural development. There are conflicting data on NH₃ emissions from broiler production across the United States. The purpose of this research is to compare emission rates from a Georgia broiler operation across seasons and with other geographical areas in the United States. Comparison of seasonal and geographical emission rates showed large seasonal variation in NH₃ emissions for eastern U.S. sites but little seasonal variation in the semi-arid region of the United States. Differences in production management practices, ambient temperature, and animal density did not appear to explain differences in emissions between regions; however, the climatic influence of ambient humidity and litter management practices are thought to be key factors in the generation of emissions.

肉鸡生产中的氨气排放和扩散

氨 (NH ₃ ) 已被用作滋扰投诉的目标气体，以限制或关闭侵占农村发展的家禽业。美国各地的肉鸡生产中的NH ₃排放数据相互矛盾。这项研究的目的是比较佐治亚州肉鸡经营活动在整个季节以及与美国其他地理区域的排放率。季节性和地理排放率的比较表明 NH _{3 的}季节性变化很大美国东部地区的排放量，但美国半干旱地区的季节性变化很小。生产管理实践、环境温度和动物密度的差异似乎不能解释地区之间排放的差异；然而，环境湿度和垃圾管理做法的气候影响被认为是产生排放的关键因素。
