We aimed at investigating the difference in N₂O emission factors of chemical and organic fertilizers and identifying the main factors influencing annual fluctuations in N₂O emission. We conducted two-year experiments in 2016 and 2017 in an agricultural field planted with sweet potato (Ipomoea batatas). Treatments included chemical NPK fertilizer (NPK) and chicken compost application at 10 ton ㏊<SUP>-1</SUP>, 20 ton ㏊<SUP>-1</SUP>, and 30 ton ㏊<SUP>-1</SUP> rates (CK1, CK2 and CK3). Control was also employed with no addition. Results showed that N₂O emission rates were significantly related with soil water status and soil available N contents. Significant correlation between % water filled pore space (WFPS) and N₂O emission was observed only when the %WFPS was greater than 40% and during the initial stage of the experiment (<60 d). Comparison of the emission factors in 2016 and 2017 showed us that the emission factor was greater in 2016 when the %WFPS was maintained higher by 16.5% compared to that in 2017. In 2016, the emission factor of organic fertilizer was higher than that of chemical fertilizer, while in 2017, the pattern was reversed. Annual variability in N₂O emission could also be originated from the available N contents remaining in soil after being taken up by plants. If we apply excessive N fertilizer, the soil would contain excess amount of N which was not uptaken by plants, leading to a huge increase in N₂O emission. This case would overestimate emission factor, which was the case for the organic fertilizer in 2016. Over-fertilization should be avoided when we set up an experiment to determine N₂O emission factor.
