The soils, a sandy clay loam and a clayey Oxisol, were studied under three tillage systems - conventional tillage (CT), reduced tillage (RT), and no-till (NT) - for five to eight years. The carbon stock of native, uncultivated soils provided a baseline for comparing the tillage treatments. While soil carbon under conventional tillage did not decrease significantly from the native soil levels, soil under no-till had increased carbon sequestration. Widespread adoption of no-till methods in the region could result in a contribution toward global climate change mitigation.text/plainen-USIn CopyrightCarbon sequestrationConservation agricultureTropical zonesSustainable agricultureConservation tillageSoil organic matterC sequestrationNo-tillTropical soilsEcosystem Field ScaleAbstractCopyright 2005 Elsevier B.V.
