Abstract

This study had the objective of evaluating the variation of nitrogen and phosphorus in soil fertirrigated with effluent of primary treatment of wastewater from swine. Tomatos of the variety Fanny TY were cultivated in lisymeters of drainage under protected environment and fertirrigated with filtered wastewater from swine (FWS) at different doses with and without application of additional fertilizer. The results showed that: increments in the FWS doses resulted in more abortion of phosphorus; in comparison to the initial conditions, there was increase in the concentration of available phosphorus, specially in the superficial layers; FWS addition resulted in increments in the nitrogen concentration in the superficial layers, while the chemical application of fertilizer resulted in larger displacement in the soil profile.
