%X The increasing size of swine farms poses an environmental risk to water bodies, considering that manure is generally applied to croplands without appropriate agronomic criteria. Objective: the present work aimed to evaluate various chemical changes occurring in soils fertirrigated with filtrated wastewater from swine facilities (FWS). Methods: 21 drainage lysimeters filled with Dystrophic Red-Yellow Latossoil were cultivated with tomato plants in protected environments, and fertirrigated with several doses of FWS, with and without fertilizer addition. Treatments were: T1: control (provided the recommended irrigation and fertilization needs for tomato plants). Treatments T2, T3, and T4, provided 100, 150, and 200% of recommended nitrogen (N), respectively, by adding filtered swine wastewater. Treatments T5, T6, and T7 provided equivalent N percentages with fertilizer addition. The experiment was conducted in a completely randomized design (seven treatments and three replications). Results: compared with initial conditions, an increase in the concentration of available phosphorus was observed, mainly in the superficial layers. The FWS addition resulted in increments in N concentration in the superficial layers, while chemical fertilizer application resulted in larger displacements in the soil profile. Conclusion: chemical fertilization was more effective than FWS for ionizing the soil solution. El aumento en el tama o de las granjas porcinas supone un riesgo ambiental para los cuerpos de agua, teniendo en cuenta que el esti谷rcol se aplica generalmente a las tierras de cultivo sin adecuados criterios agron車micos. Objetivo: el presente trabajo tuvo como objetivo evaluar los diversos cambios qu赤micos que ocurren en los suelos fertirrigados con aguas residuales de instalaciones porc赤colas (FWS). M谷todos: 21 lis赤metros de drenaje llenos con Latosuelo distr車fico rojo-amarillo fueron cultivados con plantas de tomate en ambientes protegidos, y fertirrigados con varias dosis de FWS, con y sin adici車n de fertilizante. Los tratamientos fueron: T1: control (prove赤a la irrigaci車n y fertilizaci車n recomendada para las necesidades de las plantas de tomate). Los tratamientos T2, T3 y T4 suministraron el 100, 150 y 200%, respectivamente, del nitr車geno (N) recomendado, mediante la adici車n de las aguas residuales filtradas. Los tratamientos T5, T6 y T7 proporcionaron los mismos porcentajes de N mediante la adici車n de fertilizantes. El experimento se realiz車 en un dise o completamente al azar (siete tratamientos y tres repeticiones). Resultados: al comparar con las condiciones
