| Abstract | ||
| Four water qualities at Al-Jazeera northern irrigation project(irrigation. Drainage. Well and sulfatic waters) were selected to study their tendency in precipitation and dissolution of associated minerals. Soluble ions of the applied waters as an input data in mmolcl-1 were entered into the Visual Minteq program which calculate the saturation index values of the established soil minerals. And the predicted program WATSUIT which accounts for the precipitation and dissolution of important soil minerals (primarily CaCO3 and CaCO4 .2H2O) on the composition of soil solution within the root zone. The outputs of Visual Minteq program revealed the outstanding of sulfatic irrigation water in the number and quantity of salt minerals precipitated (i.e. calcite. Ordered and disordered dolomite. Aragonite. Vaterite and gypsum). WATSUIT model exhibited higher quantity of CaCO3 and gypsum when irrigating with sulfatic water ranged between (1.74-48.77) and (13.21-182.75) mmolcl-1 respectively at all quarters of the root zone. | ||
