摘要：

The soil degradation is related to inadequate use of tillage systems, which result in decrease of organic matter content, chemical fertility and physical attributes. The no-tillage system is effective in protection of the soil surface. This study aimed to evaluate the carbon content of the oxissol under conventional tillage, no-tillage and pasture systems, using a secondary forest in regeneration as reference. As smaller the mobilization and larger the maintenance in soil of the vegetable residue, larger were the content of organic carbon and of residual carbon.
