Abstract
The level of nitrous oxide (N₂O), a long-lived greenhouse gas, in atmosphere has increased mainly due to anthropogenic sources, especially application of nitrogen fertilizers. Quantifying N₂O emission in the agricultural field is essential to develop national inventories of greenhouse gases (GHGs) emission. The objective of this study was to develop an emission factor to estimate the direct N₂O emission from an agricultural field cultivated with the Chinese cabbage during autumn season in 2010-2012. Emission factor of N₂O calculated over three years experiment using accumulated N₂O emission, nitrogen fertilization rate, and background N₂O emission was 0.0058±0.00254 kg N₂O-N kg -1 N. More extensive studies need to be conducted to develop N₂O emission factors for other upland crops in the various regions of Korea because N₂O emission is influenced by many factors including climate characteristics, soil properties, and agricultural practices as well as crop species.
