Abstract: The study was carried out on central Iraqi soil and included 28 different saline and texture sites with a depth of 0-30 cm. These included areas of central Iraq governors (Baghdad, Babylon, Karbala, Najaf and Diwaniya). The results indicated that the electrical conductivity values of soil samples ranged between 2.20 - 206.92 dS m-1 in Kufa and Shamiya sites respectively. The results indicate that the ionic strength values in the soil according to Lewis and Randol equation and using Abed program ranged from 0.03-2.83 Moll-1. The values of ionic strength in the Griffin and Jurinak equation range from 0.03-2.69 Moll-1. The following equation was found: y = 0.959x + 0.0131 during which the approximate values of ionic strength and standard error of R = 0.9991. And the SAR values are corrected before the ion pair between 10.29 and 365.97 Meql-1 at the sites of Kufa and Kefal districts, respectively. The ion pair (free ions) ranged from 11.08-405.24 Meql-1 to the same sites Nilai. In the relationship between SAR values before and after correction, we find the following equation, which can be applied by finding SAR values after correction y = 1.1029x + 0.0984 and the standard error of R = 0.9998. While Adj. RNa values ranged from 10.56-368.28 Meql-1 to the same SAR sites above respectively. The following linear equation was found for the relationship between SAR and Adj. RNa y = 1.0038x + 0.4308 was obtained by which the values AdR. RNa can be extracted and by standard error R = 0.9999. The objective of the study to estimate the ionic strength in two ways methods: the first by Lewis and Randull equation using Abed and the second by Griffin and Jurinak. The objective of the study to determine the actual concentrations of ions based on thermodynamic calculations concentrations of the main ions present are corrected and the sodium absorption rate SAR of the free ions is reassessed these values are compared with pre-correction ratios for areas of central Iraq. The objective also of the study finding the relationship between SAR and Adj. RNa for areas of central Iraq.
