| Nitrogen dioxide (N2O) accounts for the third largest share of global greenhouse gas emissions after carbon dioxide (CO2) and methane (CH4). The agricultural sector produces 24% of the world's N2O emissions, and 81% of N2O generated from agricultural land is from the use of nitrogen fertilizers. When nitrogenous fertilizers are applied to the soil, N2O is generated by microorganisms during the denitrification process. N2O emissions from the soil are affected by temperature, pH, rainfall, fertilizer use, and cultivation method, among other factors. In this study, N2O emission characteristics were analyzed according to temperature and humidity for a one-month period of urea fertilizer use in cabbage fields. Immediately after fertilizer application, N2O flux increased and gradually decreased. Correlation analysis of N2O flux revealed a positive correlation with temperature and a negative correlation with humidity. In the future, studies on other factors affecting N2O emissions are needed. | |
