To reduce the negative effects of using treated wastewater (TW) on soil properties, several techniques, methods, and strategies are used. One of these new techniques is electromagnetic (EM) water treatment technology. Using the aqua-4D physical water treatment device, we studied the effect of irrigation with electromagnetically treated TW (ETW) on soil and drainage water characteristics. Replicated pot experiments involving electromagnetically treated and non-ETW applied to cultivated and uncultivated soil were conducted under shelter. Results showed that irrigation with ETW increases soil moisture, soil electrical conductivity (ECe) and soil available K, whereas it decreases soil alkalinity (pH) and soil chemical contents such as Na+, Cl–, Ca2+, Mg2+, and SO4 compared with non-ETW, for both uncultivated and cultivated soils. It was also observed that irrigation with ETW caused a significant increase in volume, electrical conductivity (EC), and soluble salts of drainage water compared to non-ETW. In this regard, our study has shown promising potentials for EM treatment to use TW in agriculture as well as to improve soil quality.
