The book examines study water quality and to the suitability for its use for irrigation purposes, also its effects on physical and chemical soil properties . there Parameters used for irrigation water quality assessment such as EC, pH, TH, SAR, Adj SAR, SSP, RSC, Mg ratio and Cl, also some heavy metals B, Cu, Mn, Fe, Pb, Zn, Cd, Co and Cr . There were notable effects for irrigation water on some physical soil properties such as soil texture, bulk density and saturated water content and some soil chemical properties such as pH, EC, soluble ions and exchangeable cations.
