Appropriate techniques of residue management systems and forest soil preparation can improve the balance of ecosystems and their sustainability. Based on this context, this study objective to evaluate the influence of the system of soil preparation and residue management on soil carbon storage; evaluate the influence of soil management system and waste in the productivity of Eucalyptus grandis in two crop rotations; determine the accumulation of biomass and nutrients in different compartments of the aerial biomass of Eucalyptus grandis, evaluate the effect of soil management system on the quantity and quality of organic matter; conduct a nutritional balance in different management systems to infer about the sustainability of each system used, based on two rotations. The experiment was installed in July 1995 into a forestry company located in Itatinga - SP. The experiment was designed in randomized blocks with five treatments and four replicates, with plots of 11x11 plants. The treatments consisted of different waste management systems, and two intensities of preparation (localized and total area). The responses of the treatments will be evaluated by means of biometric data, nutritional assessment of the settlement, soil characteristics, physical and chemical characteristics of organic matter, nutrient balance and carbon storage in soil. The data will be submitted to descriptive statistics and analysis of variance and the relationship between the dependent and independent variables will be performed by means of correlation and regression.
