Volcanic soils contain a large stock of soil organic carbon (SOC) which is highly vulnerable to changes in land use and climate warming. In this study we examine the changes of SOC stocks along a tropical elevation gradient (100 m–700 m; +437 mm yr−1 of rainfall and −0.7 °C every 100 m), which is su...
