Leaching of Salt Affected Silty Loam Soil by using Magnetized Water

Abstract

Magnetized water is achieved by passing water through a field of magnet. Over the few past decades, many studies and researches have reported significant evidences that some properties of water can be changed as it passes through a magnetic field. The change in the physical properties of water can improves the use of water in different arias.  It can have a promising potential of application especially in the fields of irrigation and drainage. However, the effects of magnetic field on properties of water are not yet being well developed and is still a challenging subject.In this research, magnetized water was used to leach salt affected silty loam soil. A laboratory test rig was designed and constructed for this purpose. The rig consists of a constant head reservoir, a variable intensity water magnetization device, soil columns, and drain collection tanks.  Five different magnetic intensities and five different times of exposure were used in the treatment of water used for leaching soils. Leaching water drained form the soil samples were tested for EC and pH. EC is a general indicator for all anions and cations being leached. Results were analyzed and compared to the tests results of leaching of soil by using untreated water.The results showed that the efficiency of magnetized water in removing salts from the soil is more than the untreated water. As the magnetic intensity and the time of exposure are increased, the more salts were leached out of the soil.
