Keywords: wastewater | effect on soil | conductivity.

The present study aimed to evaluate the effects on wastewater from swine (WS) in the electrical (EC) and hydraulic (K0) soil conductivity. For this, tomatos of the variety Fanny TY were cultivated in lisymeters of drainage under protected environment and fertirrigated with WS different doses with and without application of fertilizer complementation. The results showed that: a chemical fertilizer was more effective in the ionization of the soil solution of the WS, with higher values of CEes treatments receiving low irrigation ARS and greater amounts of chemical fertilizer; K0 increased under intake of salts and organic matter, resulting from chemical fertilizer, irrigation and fertirrigation with ARS, which led to the restructuring of the soil in lysimeters.
