Report Errors
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.
