Resumo: | ABSTRACT The disposal of treated effluents on soil is the main final use of wastewater in Brazil. Although this practice can promote improvements of some soil attributes, there is a need for monitoring in order to ensure that potential environmental impacts are not harmful. Thus, the purpose of this study was to evaluate the effects of treated effluent from a poultry slaughterhouse on the chemical attributes of an Oxisols, in Matelândia-PR, Brazil under drip irrigation. The soil attributes P, K, Fe, Cu, Zn, Mn, pH in CaCl2, H + Al, Al, Ca, Mg, cation exchange capacity (CEC), and percent base saturation (V) were evaluated under four effluent application rates, 0, 100, 200 and 300 m³ ha-1 d-1 with treated effluents on three successive sampling dates. As main results it was observed that high irrigation rates increased soil phosphorus and potassium concentrations. In addition, an association between the increase of soil potential acidity and exchangeable acidity was detected, although pH did not vary significantly either between treatments or between sampling dates.
