【 摘 要 】

The purpose of the study was to evaluate, under greenhouse conditions, using soil columns and cycles of wetting, the effect of residues from the extraction of cellulose on the chemical composition of the soil solution and on the two Red Oxisols. The experimental design was completely randomized. The treatments were: T1 - without the 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 of lime mud; T5 - 2.4 t ha-1 ash, T6 - 1.8 t ha-1 dregs/grits + lime mud + ash in the ratio 1:3:6, T7 – 1.0 t ha-1 dregs/grits + lime mud in the ratio 1:3. Evaluation was performed of the chemical composition of the solution extracted from each soil during four months of incubation and also chemical analysis of soil thereafter. The results were analysed by performing analysis of variance and Tu
