In this study, the level of cations and anions of saline soil leaching was investigated in laboratory conditions by using of magnetic water. silty loam Soil was poured in 50 cm height and 10 cm diameter pipes while the end of each pipe was closed with a filter paper and a plastic net. leaching was conducted alternatively after passing water through the magnetic field with different intensities. The drained water was collected from the end of soil columns and analyzed chemically in the laboratory. The final results showed that the amount of the leaching of sodium, potassium, chlorine and sulfate in the magnetic treatment was significantly more than control treatment (a<0.05). In addition, applied the different magnetic treatments have no significant effect on leaching of magnesium and bicarbonate and the value of calcium leaching was significantly less than control in magnetic treatments.
