Abstract

Water analysis indicated that Sarir-Sirt I Tazerbo-Benghazi System water is worth mentioning that when mixing the water of Tazerbo wells field with that of Sarir wells field in a proportion of 1: 1, it was revealed that this water is appropriate
chemically for drinking and it conforms to the standard specifications and criteria of
drinking water.
The mean salinity value of irrigation water was around EC 0.90 - 0.94 dS/m. In general, the SAR mean value was around 3.28 - 3.74 %. There is no potential restriction on water use due to boron and nitrate concentration. The water was assessed according (U. S. Salinity laboratory staff method, 1954) and furthere evaluated according to the guidelines of water quality for irrigation (FAO, 1985). The assessment showed that all irrigation water classified according to the American salinity laboratory's scheme on the water system of (Sarir-Sirt I Tazerbo-Benghazi).
From the electrical condLictivity value and sodium adsorption ratio (SAR) data, it is clear that this water system lies among the kind of (C3S1) Khigh saline low sodicity water". This means that water is not suitable for sensitive crops especially the citrus trees. It is suitable for use only in good permeable soils. The application of the FAO's guidelines to evaluate the irrigation water quality of the (Sarir-SirtTazerbo-8enghazi) water system. From the results of water analysis listed in the Salinity Problem. It was found that the electrical conductivity (EC) equals 0.90 - 0.94 dS/m. In other words, there is a possibility of increasing the problem when using this water for irrigation.
