Chemical alterations in the soil after application of residues from recycled paper factory. The study of effects of the residues from recycled paper factory on forest soils in the chemical properties of two kinds of soil, was the main goal of this work. The residues utilization, even with low quantity of nutrients is defended by several authors, aiming mostly conciliate the nutritional needs with the nutrients cycling process to keep the productivities of the forest plantings. Using the residues from recycled paper factory was accomplished the rehearsal at green house of EMBRAPA, in Colombo (PR). Were mounted PVC pipes with residue mixture and two kinds of soil, Neossolo Regolitico distrofico humico and Cambissolo humico distrofico typical. The experiment was accomplished in blocks entirely randomized, with three repetitions, with increasing residues dosages (0, 10, 20, 40 and 80 t. ha). At the end of the experiment, after 147 days, was accomplished the analysis of three soil layers: 0-10 cm; 10-20 cm and 20-30 cm. The residues application of recycled paper influenced the soil chemical properties like pH increase; decrease in the exchangeable aluminum; decrease of the potential acidity; increase in the calcium and magnesium levels; increase in the initial layers for the phosphorus; increase in the saturation bases; without alteration of sodium content and of the organic matter of the soil.
