Resumo: 	Soil quality is a concern that every year becomes more and increasing current. With intensive farming worldwide, mainly in tropical countries, systems that aim at conservation of the chemical, physical and biological soil become a viable alternative for maintaining soil quality and sustainability of ambeinte. Thus, the objective of this work is to expose a revision that demostre the relationship of physical and chemical properties of soils that have different rates of organic carbon in the conditions of Cerrado in Brazil. For these environments the levels of soil organic matter - MOS and organic carbon - CO are associated and dependent on the rates of addition of waste and the intensity of the processes of decomposition of soil organic matter - MOS. Therefore, managements seeking increased MOS as tillage - PD tends to accumulate the COS, as results observed an increasing of the aggregation index, greater water-holding capacity, higher porosity and greater resistance to erosion. In addition, the soils had better fertility and soil quality and hence greater productive capacity. However, the input MOS is also correlated with climatic conditions (rainfall, temperature, etc.), texture (clay, silt and sand), soil structure and biogeochemical factors of the environment.
