Transmission of water through a magnetic field will cause some changes in water characteristics, affecting the overall behavior of water molecules including increasing solubility of some of compositions and decreasing water surface tension. This study was conducted with the aim of examining the effects of magnetic water on the level of remaining cations and anions of saline soil, in laboratory conditions, in a compeletly randomaized design. Soil with loam silt texture was poured in pipes with the height of 50 cm and diameter of 10 cm while the end of each pipe was closed with a filter paper and a plastic net. By passing water through the magnetic field with different intensities (6500 Gaousses in first magnetic treatment, 8000 Gaousses in second magnetic treatment), leaching was performed alternatively. At the end of the leaching experiment, the experimental soil was divided into three equal depths and amount of cations ana anions was measured. The result of chemical analysis showed that the avrage amount of the remaining sodium of the soil in the first magnetic treatment, 11.7 %, and in second magnetic treatment, 22.8 %, was lower than the controlled treatment. The avrage amount of the remaining potassium of the soil in the first magnetic treatment, 2.8 %, and in second magnetic treatment, 8.5 %, was lower than the controlled treatment. The avrage amount of the remaining calcium of the soil in the first magnetic treatment, 2 %, and in second magnetic treatment, 16 %, was lower than the controlled treatment. The avrage amount of the remaining magnesium of the soil in the first magnetic treatment, 6 %, and in second magnetic treatment, 13 %, was lower than the controlled treatment. The avrage amount of the remaining chlorine of the soil in first magnetic treatment, 14 %, and in second magnetic treatment, 14.7 %, was lower than the treatment. The avrage amount of the remaining sulfate of the soil in the first magnetic treatment, 2 %, and in second magnetic treatment, 5.8 %, was lower than the controlled treatment.
