Salinization is a process that can be triggered naturally and by human action in nature. The aim of this study were evaluate the soil salinity in irrigated perimeter Jacaré-Curitiba in Sergipe state. Soil samples were collected at depths of 0.00.15 m and 0.15-0.30 m. The parameters determined were SAR, EWCes, Calcium (Ca), sodium (Na), Potassium (K), Magnesium (Mg) carbonate and bicarbonate. Soil salinity levels have been classified according to the proposed by Richards (1954). The results showed that the irrigated perimeter presents salinity levels: saline soils, sodic saline and sodic. Results allowed concluding that the perimeter is in an advanced salinization process, and the lack of adequate management accelerates the process.
