Cl- > SO4-2 > CO3-2 and Na+ > Mg+2> Ca+2 > K+. Also, the examined samples for its content of macro and micro nutrients can be arranged as K > NO3-N > NH4-N > P and Fe > Cu or Mn >Zn, respectively. The studied water samples have pH values ranged between 6.88 and 7.89. The analytical results indicated that, 14.28%, 57.15%, 64.29%, 92.86% of ground water samples classified as a good order based on EC, RSC, % Na and KR parameters, respectively. On the other hand, 100% of groundwater sample is excellent for irrigation purposes based on SAR, while 50% of samples are marginally for irrigation dependable on its nitrate content. The dominant hydrochemical facies of groundwater is Ca-Mg-HCO3 and Na-Cl-SO4 type. Assessment of water samples from various methods indicated that groundwater in the study area is chemically suitable for agricultural uses without any harmful effect on soil or plant.]]>

Zn>Mn. Cu was the trace element most strongly adsorbed by all soils, whereas Zn and Mn were the least adsorbed in the competitive situation. The relationships between maximum adsorption and partitioning coefficients of Cu, Zn and Mn and clay content were quantitatively modeled.]]>
