Abstract

The present study aimed to evaluate the variation chemical (electrical conductivity, phosphorus and nitrogen) of an dystrophic red-yellow latossol fertilized with wastewater from swine after filtering process (FSW). For this, tomato plants of the variety Fanny TY were cultivated in drainage lisymeters in a greenhouse, and fertirrigated with different doses of FSW, with and without added chemical fertilizer. The results showed that the c treatments that received lower FSW doses and higher quantities of chemical fertilization presented higher values of electrical conductivity of the saturation extract of soil (ECs); there were an increase in the concentration of available phosphorus, mainly in the superficial layers; the FSW addition resulted in increments in the nitrogen concentration in the superficial layers, while the chemical fertilizer application resulted in larger displacement in the soil profile.
