In this study, the effect of magnetic water on the soil saturated hydraulic conductivity has been investigated by a quite random form with four treatments and three repetitions. Treatments in this study were included: 1- potable water after passing through the RPM device with 500 Gauss Intensity; 2- potable water after passing through the Aqua Correct device with 1300 Gauss Intensity; 3- potable water after passing through the Elcla device with 1600 Gauss Intensity; 4-potable water without magnetic device (Reference treatment). Hydraulic conductivity was measured by constant head test. 12 high pressure plastic pipes were used for preparation of the soil columns. The columns were fixed at new metal table with constant height form the ground in order to gather the drainage, easily. Also agricultural soil with loam texture was compressed into the columns up to 15 cm. During 35 days, the water with 2 cm height was passed over the top of soil columns. At the end of 35 days, magnetic water had significant effect (1%) on decreasing saturated hydraulic conductivity. The third magnetic treatments had lowest hydraulic conductivity that it was 51% less than reference treatment. For the first and second treatments, it was 29.3 and 36% less than reference treatment, respectively.
