Methane is considered the second most important greenhouse gas in the atmosphere and has 21 times high global warming potential(GWP) of CO2. Methane emissions have increased by more than 150% since 1750, with agriculture being the major source for human living. In Korea, approximately 22% of domestic methane(CH4) emissions are emitted from rice cultivation. Study for reducing methane emission from paddy soil is needed. Biochar has the potential to mitigate CH4 emissions from flooded soils that has characteristic of wetlands and irrigated fields cropped to rice(paddy soils). In this study, biochar(BC) is pyrolyzed from diverse temperature and time condition. BC pyrolyzed from 200,300,400,500°C(BC-200, 300, 400, 500) and lasted for 1,3,5 hours are injected to rice paddy and monitored to evaluate which one has best potential for reducing methane. For BC-500 sample, methane generation rate(MGR) is high at week 4 while BC-300,400 sample has highest MGR at week 5. For blank and BC-200 sample has highest MGR at week 6. Further monitoring is needed to evaluate which BC has a high potential for mitigating CH4.
