The atmospheric concentration of nitrous oxide(N2O), which is one of the main greenhouse gases, is increasing every year. The N-fertilizer application such as chemical fertilizer and manure compost in agricultural land is one of the most important sources of increasing concentration of N2O in the atmosphere.
The purpose of this study is was development of country specific emission factor for application of chemical fertilizer and manure compost in rice field. The field experiment was carried out during 4 years from 2009 to 2012 at the rice paddy field located in Suwon, Gyeonggi province, south of Korea.
The total emissions for fertilizer application were the highest in 2009 and the lowest in 2012. The average N2O emission factors for chemical fertilizer 0, 80, 110, 140 kg ha-1 application during 4 years were 0.00124, 0.00369, 0.00395, 0.00495 N2O-N kg / N kg, respectively and the total N2O emission factor was 0.00337 N2O-N kg / N kg. This factor was similar level in comparison with default value which is 0.0031 N2O-N kg / N kg of 2006 IPCC guideline.
The total emissions for manure compost applicat ion in paddy rice field have had similar results like as the treatment of chemical fertilizer. The average N2O emission factors for chemical fertilizer 0, 80, 110, 140 kg ha-1 treatment were 0.00112, 0.00247, 0.00207, 0.00240 N2O-N kg / N kg, respectively and the total N2O emission factor was 0.00202 N2O-N kg /N kg. This result was 33% less than default value which is 0.0031 N2O-N kg / N kg of 2006 IPCC guideline.

It was evaluated N2O emissions with different growing periods red pepper, soybean and chinese cabbage field. The results were as follows :
1) By cultivation and no cultivation conditions, N2O emissions were reduced to 35.5∼50.6% in cultivation than no cultivation conditions in red pepper field, to 22.7∼26.0% in cultivation than no cultivation conditions in chinese cabbage field and to 25.8∼34.5% in cultivation than no cultivation conditions in soybean field 2) The average N2O emission factors for red pepper, chinese cabbage and soybean field application during 4 years were 0.0064, 0.0018 and 0.0052 N2O-N kg / N kg, respectively, and There factors were lower than that of the IPCC default value (0.0125 kg N2O-N/kg N).

The average total N2O emissions of each crop treatment at the red pepper, soybean, and chinese cabbage field were following as ; red pepper 2.169(N 0), 3.165(N 0.5), 5.235(N 1.0), and 7.228(N 2.0) kg N2O ha-1 yr-1, soybean 1.694(N 0), 2.006(N 0.5), 3.012(N 1.0), and 3.347(N 2.0) kg N2O ha-1 yr-1, and chinese cabbage 1.282(N 0), 3.329(N 0.5), 4.676(N 1.0),and 9.233(N 2.0) kg N2O ha-1 yr-1. And then the average default values of the crops were red pepper EF1 0.0151(0.0123~0.0179), soybean 0.0403(0.0337~0.0454), and chinese cabbage 0.0136(0.0132~0.0139) N2O-N kg N-1 kg-1 during cultivation. These results were in similar tendency as in the default value of the IPCC 2006 guideline EF1 0.01(0.003~0.03) at upland when the results are converted into emission defaults.

The objective of the study was to develop emission factor to estimate direct N2O emission from agricultural field in Gangwon-do, Korea by measuring N2O emissions from potato (Solanum tuberosum), red pepper (Capsicum annum L.), and Chinese cabbage (Brassica campestris L.) cultivation land from 2009 to 2012. Mean N2O emissions (±standard deviation) from field cultivated red pepper, potato, and Chinese cabbage grown in spring and fall were 1.48±0.25 kg N2O-N ha-1, 1.27±0.27 kg N2O-N ha-1, 1.49±0.06 kg N2O-N ha-1, and 1.14±0.22 kg N2O-N ha-1, respectively, as compared with 0.45±0.15 kg N2O-N ha-1 for background emission from non-fertilized soil. The estimated fertilizer-induced emission factor of N2O was 0.0051±0.0016 kg N2O-N kg-1 N.

This study was conducted to investigate the characteristic factors which have been influenced on nitrous oxide (N2O) emissions related to the environment change of nitrogen application level, rainfall and temperature during the potato cultivation at black volcanic ash soil from 2010 to 2012. During the soybean cultivation, the average emissions factor of 2 years released by the nitrogen fertilizer application was presumed to be 0.0268 (kg N2O-N N-1 kg-1). This factor was higher about 3.7 and 2.7 times than the Japan's (0.0073 kg N2O-N N-1 kg-1) value and 2006 IPCC guideline default value (0.0100 kg N2O-N N-1 kg-1) respectively. During the carrot cultivation period, the average emissions factor released by the nitrogen fertilizer application for 3 years was presumed to be 0.0067 (kg N2O-N N-1 kg-1). This factor was 0.67 times than the IPCC (0.0100 kg N2O-N N-1 kg-1) factor. During the potato cultivation period, the average emissions factor of 3 years released by the nitrogen fertilizer application waspresumed to be 0.0082 (kg N2O-N N-1 kg-1). This factor was lower about 0.82 times than the IPCC guideline default value (0.0100 kg N2O-N N-1 kg-1).

This experiment was conducted to measure concentration of dissolved N2O in ground-water of 59 wells and to make emission factor for assessment of indirect N2O emission at agricultural sector in agricultural areas of Gyeongnam province from 2007 to 2010. Concentrations of dissolved N2O in ground-water of 59 wells were ranged trace to 196.9 μ g-N L-1. N2O concentrations were positively related with NO3O-N suggesting that denitrification was the principal reason of N2O production and NO3O-N concentration was the best predictor of indirect N2O emission. The ratio of dissolved N2O-N to NO3O-N in ground-water was very important to make emission factor for assessment of indirect N2O emission at agricultural sector. The mean ratio of N2O-N to NO3O-N was 0.0035. It was greatly lower than 0.015, the default value of currently using in the Intergovernmental Panel on Climate Change (IPCC) methodology for assessing indirect N2O emission in agro-ecosystems (IPCC, 1996). It means that the IPCC's present nitrogen indirect emission factor (EF5g, 0.015) and indirect N2O emission estimated with IPCC's emission factor are too high to use adopt in Korea. So we recommend 0.0034 as national specific emission factor (EF5g) for assessment of indirect N2O emission at agricultural sector. Using the estimated value of 0.0034 as the emission factor (EF5g) revised the indirect N2O emission from agricultural sector in Korea decreased from 1,801,576 ton (CO2O-eq) to 964,645 ton (CO2O-eq) in 2008. The results of this study suggest that the indirect Emission of nitrous oxide from upland recommend 0.0034 as national specific emission factor (EF5g) for assessment of indirect N2O emission at agricultural sector.
