Abstract

The salinity of irrigation water and soil are the major challenge factors for expansion of agricultural area in Egypt. Moreover, salt concentrations cause a lot of problems for soil and plants especially under pressurized irrigation systems. However, the usage of magnetic water treatment may help in solve the problem. Therefore, this investigation was conducted to descript the effect of magnetic field on the properties of irrigation water. Magnetic devices with two intensities (1600 and 14500 Gauss “G”) were used to treat three saline water levels (tap water with 219 ppm, 1000 ppm and 2000 ppm).
It was found that magnetization affects dynamic viscosity, dissolved oxygen, surface tension and pH. Also found a positive effect of magnetization on the total number of microorganisms. On the other hand, There is a slight increase on electrical conductivity due to magnetism, and it increases more over time. The viscosity of water was decreased under magnetic treatment. The surface tension dropped by 1.5% and 3% when the salinity increased from 219 to 1000 and 2000 ppm respectively. The total number of microorganisms decreased by 17.1% and 57.3% at 219 ppm, by 38.6% and 57.5% at 1000 ppm and by 32.5% and 55.5% at 2000 ppm comparing to non-magnetic water under 1600 and 14500 G, respectively.
