This study aimed to evaluate the quality of a soil subjected to different irrigation times with fish farming effluent in the western region of Bahia, Brazil. The study was carried out in 3 properties in the irrigated perimeter of São Desidério/Barreiras Sul: property that did not carry out fish farming activities (T1); with 5-year-old (T2) and 20-year-old (T3) nurseries, with cultivation mainly of Tambaqui (Colossoma macropomum). For the characterization of water quality, samples were collected from fishponds in T2 and T3 and from the supply channel. To assess soil quality, preserved and nonpreserved samples were collected. In the physicochemical analyses, the water from fish farming shows turbidity and increased levels of ammoniacal nitrogen in the effluents. There are changes in the porosity, soil density and height of water stored in the soil, indicating compacted soils. Decreased micronutrients and macronutrients suggest leaching losses. The proper management of the effluent and of the receiving soil is essential to enable the use of fish farming effluent in agricultural activity.
