Abstract: NH3 is one of the leading causes of grey haze, and one of the main causes of serious ecological imbalances that result in environmental problems such as acid rain and air quality deterioration. At present, excessive fertilizer application greatly intensifies NH3 emissions intensity on farmland. In order to understand status and achievements of research on farmland NH3 emissions, the literature of farmland NH3 emission-related studies was retrieved from SCI journals and the Chinese science citation database. These are summarized with respect to the research progress on NH3 emission factors and emission reduction technologies. The future research direction of field NH3 emission and emission reduction technology need to strengthen the field observation on different soil environment and crop types, and understand the effect of NH3 emission on fertilizer application period and the proportion, temperature and organic fertilizer management in farmland mainly. The research results can provide more information about the factors that influence NH3 emissions. This study offers theoretical guidance and support directed at mitigating farmland NH3 emissions in the future.

Key words: emission reduction technology, farmland ecosystem, influence factors, NH3 emissions
