Wastewater can be applied indiscriminately to the soil, bringing great discrimination, both to swine water and important to the soil and to swine water and important. In order to evaluate the polluting potential of different doses of swine wastewater, a soil study was carried out to study a two-ion project in dystroferric and its red argisols in dystroferric and its red argisols from Paraná (Brazil) and its influence on leachates generated. The analyzed treatments consist of a 2 x 2 x 2 factorial scheme for soil, doses and pH value. The experimental units were a total of 48 and the treatments were performed in triplicate. The application rates corresponded to 0, 50, 100 and 150 m-3.ha-1. The pH value of both soil and leachate remained in the acidic range, although the initial pH value of the soil and swine wastewater proved to be basic. The nutrient ion had more direct influence on the electrical conductivity of the leachates. The V% did not have a significant individual value due to the application of swine wastewater, so the CEC was high in the step in the argisol. The same occurred with ESP, showing that the nitosol was prone to salinization.
