Short summary
The rapid expansion of rubber cultivation constitutes a significant land-use change in Southeast Asia. Despite fertilization being a common practice in rubber plantations, its impact on soil methane (CH4) dynamics has remained poorly understood. Our study demonstrates that fertilization not only reduces soil CH4 consumption but also increases CH4 production, transforming rubber plantations from a net CH4 sink to a source. Implementing rational fertilization could enhance atmospheric CH4 removal.
