| Abstract: |
| As the largest crop-production and fertilizer-consumption country in the world, food production in China has emitted substantial greenhouse gases(methane, CH4; nitrous oxide, N2O) into the environment. Therefore, it is essential to mitigate the CH4 and N2O emissions and increase soil organic carbon sequestration (also known as "mitigation and sequestration")in croplands for retarding global warming and ensuring food security. During the past two decades, mountainous studies have conducted on this research area and have summarized a series of agricultural management practices, which are effective in mitigating CH4 and N2O emissions and increasing soil organic carbon sequestration in the cropland of China. This paper reviewed these effective "mitigation and sequestration" agricultural management practices and put forward prospects and suggestions on future studies regarding this research area in China. |
