Due to the water crisis, wastewater reuse is an effective method in order to resolve crop water requirements and decrease environmental pollution. In order to study the impact of treated and magnetic wastewater on the soil properties, a refined 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 resulting from the application of magnified wastewater. This is probably due to the increasing salt portability of magnified 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. Evaluating the apparent specific gravity of soil in different water quality treatments showed that this soil property was increased, effectively at the upperstream part of the furrow. Similar results was also observed in the field capacity but more fluctuations were observe. Simultaneously, wastewater treatment showed decreasing effects on soil capacity of holding water during the time, which can be attributed to the increasing of soil organic matters. It seems that the high fluctuations between different design blocks is related to the gravelly nature of soil. Also, the statistical analysis of the relative changes in the roughness coefficient did not show any significance difference. However, decreasing in the roughness coefficient has been observed in the irrigation season. This was expected because of the smoothing furrow bed and the effect of organic matters of wastewater on it. Intensification or weakening effect of these changes was not even affected by magnetic.
