摘要: The intensified input of anthropogenic nitrogen (N) fertilizers has accelerated the transformation of active N species (eg, N 2 O, NO 3− and NO 2−) and the coupled methane (CH 4) cycling on a global scale, but the impact of N-mediated CH 4 metabolism on soil carbon accumulation, which is crucial for agricultural sustainability, remains poorly understood. In this study, we show that more than 60% of the CH 4-C were converted to soil organic matter during anaerobic oxidation in two paddy soils with a parent material origin of …
