§16§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.
