| In Korea, approximately 22% of domestic methane (CH4) emissions are emitted from rice cultivation. Various studies have sought to reduce CH4 emission from rice cultivation, but studies conducted in Korea have not been reviewed. In this review, we suggest directions for research by summarizing CH4 study cases of rice paddies in Korea. In addition, we provide background information on CH4 emissions. In flooded paddies, an anaerobic environment develops when soil redox potential reaches -200 mV, methanogens are promoted. When substrates such as acetic acid and hydrogen/carbon dioxide, which are the decomposition products of organic matter, are supplied at the optimum soil temperature of 20-40℃, CH4 emissions are accelerated. After that, 80-90% of CH4 generated from the soil is released into the atmosphere through the aerenchyma of rice. Studies have explored CH4 emissions related to various agricultural activities that affect methanogen activity in Korea. A significant number of studies have focused on the management of paddy water and organic matter in relation to increases or decreases in CH4 emissions. However, most studies were short-term evaluations of CH4 emissions. In addition, detailed analysis of the factors influencing CH4 emission was lacking in investigations focusing on the amount of CH4 emissions. Therefore, including the effects of long-term soil management on CH4 emissions, studies should be conducted a detailed part of each affecting CH4 emission factor, in future research. These results could contribute to decreasing national CH4 emissions by providing specific measures for how to strategically reduce CH4 emissions in the future. | |
