Effects of Magnetized Municipal Effluent on Some Chemical Properties of Soil in Furrow Irrigation

Due to the water crisis, wastewater reuse is an effective method in order to supply crop water requirements. In order to study the impact of treated and magnetic wastewater on the soil properties, this research was conducted in randomized complete block design with three irrigation treatments; including "wastewater", "magnetic wastewater" and "normal water" in four replications. Soil samples were taken from two surface and subsurface soil layers and at the upper and the downstream of each furrow. The results indicated that based on the amount of soil salinity, there was no significant difference between treatments statistically; however, considerable changes in the increasing of salinity were observed on subsurface layers in the magnetized wastewater treatment. This is probably due to the increasing salt portability of magnetized wastewater and accumulation of salts in the lower soil layer. The soil pH was also affected by wastewater and was decreased. However, magnetizing the wastewater had no considerable effect on soil pH.
