ABSTRACT
The leaching of salts through facilitating the permeability process is very important for irrigation systems planning. The negative effect of soil compaction on plant growth is an integration of multidirectional influences, such as the reduction of aeration to the roots. This research was done at Babolsar city, Mazandaran province, Iran to investigate the effect of magnetized water and different irrigation water salinity treatments on cumulative and final infiltration rate and soil electrical conductivity. The experimental treatments include magnetized and non-magnetized irrigation water, different level of irrigation water salinity (0.58 dSm-1, 6.5 dSm-1, and 13 dSm-1) and variable soil texture (loamy-sand, loam, and clay). The factorial experiment was conducted with a complete randomized block design with three replications. Magnetized water was obtained by passing the water via a strong magnetic field installed on the irrigation pipeline. The results exposed that the effects of soil texture and magnetized irrigation water on the final infiltration rate and cumulative infiltration were significant (P<0.01). Final infiltration rates and cumulative infiltration in magnetized water treatment was greater than non-magnetized treatment. The magnetized irrigation water had the most effect on the infiltration capacity of clay soil. Also, the results showed that magnetized water could decrease soil electrical conductivity in the soil profile, and this effect at a 1% level was significant. It was concluded that magnetized water can be used as an effective technique for desalinization in agriculture.
