Abstract | This experiment investigated the effect of electro-osmosis on water and salt movement in soil with potential application in agriculture. A range of voltages were applied for different durations to a sandy soil in an isolated transparent acrylic plastic cell. The tests were performed at voltage gradients 3, 6 and 10 Vcm-1. The measurements included the volume of soil-water extracted from point lysimeters, electrical conductivity of the soil-water, soil-water potential (SWP) and pH value at different voltage gradients. The results showed that the electric field intensity affected the salt distribution from anode to cathode during the application of the direct electric current. Soil-water content was observed rising with increased electric field intensity. The pH of the soil-water has changed due to the effect of electrical field. |
