Abstract

The aim of this work was to evaluate, in vase, the effect of cellulosic residue in soil and chemical characteristics of effluents resulting from that application in Litholic Humic Neosol layers collected in the 0 to 10 and 10 cm to 30 cm. Doses of sludge, equivalent to 0, 10, 20, 40 and 80 Mg ha-1 were implanted in a randomized design. Aliquots corresponding to doses of sludge, collected on the treatment were mixed to the soil layer of 0 to 10 cm and placed in vessels after the completion of the soil layer from 10 cm to 30 cm. At 117 days after implantation of the test, samples were collected from the soil layer from 0 to 20 cm and from the effluent resulting from the application of water for irrigation. The treatments changed the characteristics evaluated, except the levels of organic carbon and Mg. There was an increase in pH CaCl2, in the levels of Ca, P and K and in the base saturation, with greater impact on the content of P. The concentration of exchangeable Al, the potential acidity and exchangeable Al saturation were reduced with increasing doses of the residue. There is no evidence of contamination of soil and water by the application of the residue.
