Abstract: To evaluates the leaching effects by saline water (2.0 dS m−1) on the chemical characteristics of a Red Eutrophic Acrisol. This study was carried out under cultivated with the common bean (Phaseolus vulgaris L.), in protected drainage lysimeters, at the lysimeter station of the Irrigation and Drainage experimental area of the Federal University of Viçosa, Viçosa/MG, Brazil. Treatments comprised six leaching fractions, equivalent to 40%, 31%, 25%, 23%, 16% and 14% of irrigation water depths. Soil and bean leaf chemical characteristics were performed in soil and leaf samples harvested during the filling of bean pods. N, K+, Mg2+, S, Zn2+ and B rates in bean leaves were influenced positively by leaching fractions with saline water. Results show that leaching fraction 25% increases nutrient concentration in soil solution (P, Na+, Ca2+, Mg2+ and Mn2+) and that N, K+, Mg2+, S, Zn2+, B rates in bean leaves were affected by leaching fractions. The contents of P, Ca, Na, Fe, Mn and Cu2+ rates were not significantly affected with regard to variation in leaching fractions. Soil characteristics pH (H2O), SOM, K+, Zn2+, Fe2+, Cu2+, ISNA, ESP and RAS were not influenced by leaching fractions with saline water.
