Save Disposal of Wastewater in Irrigation and its Effect on Soil Properties under Khartoum Conditions

The objective of this study is to investigate the effect of disposal of wastewater in irrigation on soil properties. Samples of treated wastewater were analyzed for pH, SAR, EC in dS/m, while, Na, Cl, NH4-N, HCO3, CO3 and heavy metals in mg/l. The soil samples were taken from three depths D1(0-20), D2 (20-40) and D3 (40-60) and analyzed for fore mention parameters. The results showed that the concentration of fore mentioned parameters showed different scenarios with soil depth. On the other hand, the levels of fore mention parameters in the soil received wastewater for a long time were very high compared with that never received wastewater. This study concluded that reusing of wastewater in irrigation is a safe disposal and conserving water from pollution.
