Paper and cellulose industry generates alkaline residues that have to be characterized to evaluate the technical feasibility of their use in agricultural soils. The objectives of this study were evaluate the effects of increasing rates of alkaline residues (Res) on a Humic Cambissol. Two experiments were carried out: the experiment I, evaluated the effects of increasing rates of residue and lime incorporated into the soil in green house conditions. The treatments were rates of lime (Cal) corresponding to 0.5 and 1 SMP and of residue corresponding to 0.2, 0.5 and 1 SMP to increase pH in the layer of 0 to 0.10 m upto 6. The experiment II was similar to the former I with lime and residues applied on the surface of a native grassland in order t...
