Conteúdo:	Soil organic matter (SOM) plays important functions in soil physical, chemical and biological processes. A reduction of SOM enhances the soil degradation process by reducing the biomass production and causing the loss of nutrients, water and soil. A mix of annual crops, tree species and pasture on the same area in an Integrated Crop-Livestock-Forest System (ICLFS) ensures abundant supplies of residues and an elevated amount of accumulated organic material in the soil thus constituting a promising alternative for tropical regions. Land areas aimed at fodder production, if well managed, produce large quantities of residues, which associated with a non-disturbed soil, favor the accumulation of SOM. In ICLFS, the cultivation of grain crops prior to the use of the land for pastures ensures more efficient use of residual nutrients by the plants, thus increasing the productivity of pastures. The adoption of technologies aiming at sustainability, as an improved soil management system, with better use of natural resources, increases the soil carbon levels. This condition results in the economic feasibility of cropping systems, through the improvement of soil, water and consequently, the environment quality. This chapter discusses the main advantages of integrated production systems and the influence of ICLFS on the supply and maintenance of SOM in tropical and subtropical regions.
