Global warming due to climate change is a problem facing the entire world. Several factors, such as CO2 concentration, level of warming, soil temperature, precipitation, water content of soil and denitrification by denitrifying bacteria influence the emission of nitrous oxide (N2O) from soil. In this study, we investigated nitrous oxide emissions from the soil of two wetlands, Jilmoineup in Mt. Odae and Moojechineup in Mt. Jungjok, according to temperature change. Soil collected in Jilmoineup in July showed increasing N2O emissions as temperature increases, but did not show any significant differences at 10℃ (p/0.05). Soil of 15℃ and 20℃ showed increasing pattern of N2O emissions until 24 h. After that, however, there was no difference in temperature. Overall, N2O emissions showed significant differences according to temperature (p/0.05). Soil collected from Moojechineup in July showed increasing N2O emissions according to temperature increase, but did not show any significant differences at 10℃ (p/0.05) as was the case for Jilmoineup soil. On the other hand, two wetland soils showed a slight increase of N2O emissions by additional nitrogen supply, but did not show any significant differences in the presence of nitrogen or between nitrogen sources. In conclusion, increasing temperature the wetland soil increased the emission of N2O, which is a known greenhouse gas. In order to more clearly identify N2O emissions, various subsequent studies such as the influence and correlation of several factors are required.
