Abstract

The great expansion of industry and consumer market has led in recent decades, the generation of large quantities of waste. With the production of pulp and paper industries in the sector have generated daily large quantities of solid waste and effluents, thus becoming a major environmental concern and economic. In order to return to these products in a sustainable manner the nature, the aim of this study is to evaluate, under greenhouse conditions using soil columns, the effect of waste from the extraction of cellulose in two Oxisol, in their physical-hydric and chemical attributes, especially those relationship to clay dispersion. The experiment will be development at the Faculty of Engineering, Campus Ilha Solteira(UNESP), located in São Paulo State, Brazil. The experimental design is completely randomized design with seven treatments and five replications. The treatments are: T1 - without addition of lime and residue (control), T2 - 1.0 t ha-1 of limestone, T3 - 1.2 t ha-1 dregs / grits, T4 - 0.8 t ha-1 lime mud, T5 - 2.4 t ha-1 gray, T6 - 1.8 t ha-1 dregs / grits + ash + lime mud in the ratio 1:3:6, T7 - 1.0 t ha-1 dregs / grits + lime mud in the ratio 1:3. It will be analyzed the physical-hydric (texture, soil bulk density and particle, soil porosity, aggregate stability, hydraulic conductivity, water retention capacity and the flux density), chemical (phosphorus, potassium, magnesium, calcium, sodium, pH, Al) before and after the incubation period. The results will be analyzed by performing the analysis of variance, simple correlation and Tukey test for comparison of means at 5% probability.
