The four tillage systems evaluated were conventional tillage (CT), mulch ripping (MR), clean ripping (CR) and tied ridging (TR). Soil organic carbon (SOC) content was measured for each size fraction as well as total SOC. Based on the findings, the authors conclude that residue management - maintaining carbon inputs - is most important for SOC stabilization in coarse-textured soils, whereas reducing tillage is the management priority for fine-textured soils.text/plainen-USIn CopyrightConservation agricultureSoil managementTropical zonesConservation tillageSoil organic matterAgricultural ecosystemsResidue managementParticulate organic matter (pom)Soil organic carbonTillageTropical agroecosystemsField ScaleAbstractCopyright Elsevier B.V.https://doi.org/10.1016/j.still.2006.08.006
