No-till (NT) system has the potential to sequester soil organic carbon (SOC) in the topsoil and increase soil quality. However, SOC accumulation in the soil profile and the mechanisms for SOC stabilization in NT are still a matter of debate, especially for soils of the tropics. Therefore, this study...
