The Effect of Thermodynemic Parameter son the Rlationship Between Exchangeable Sodium Percentage and Sodium Adsorption Ratioin Saline Soilof Iraq Central
The study was conducted to determine the relationship between the exchangeable sodium percentage ESP and sodium adsorption ratio SAR in the soil solution. Some saline affected soils were selected at the locations Yosifya, Muwayliha, Imam, Eychreesh, Mahaweel, Ejbalah, Abe-Ghragg, Kifil, Elseneya and...

| description | The study was conducted to determine the relationship between the exchangeable sodium percentage ESP and sodium adsorption ratio SAR in the soil solution. Some saline affected soils were selected at the locations Yosifya, Muwayliha, Imam, Eychreesh, Mahaweel, Ejbalah, Abe-Ghragg, Kifil, Elseneya and Eldagharaah. Using thermodynamic criteria to recalculate throught description quantitative concepts rather than analytical.The results indicate that the values of SAR range from 0.96 - 26.80 (cmol Kg-¹)º·5 of the studied sites and this ratio increased when taking into account free ions 3.52 - 32.7 (cmol Kg-¹)º·5. The ESP Calculated laboratory was (2.0 - 9.0 %) and all of these were less than ESP % according to laboratory salinity accounts, and generally show increase in the values of the proportion of ESP with increased SAR according to the approved indicators. The probability of these soils turning into sodic is unlikely to decrease pH and HCO3-¹ values and increase concentrations of calcium and magnesium ions.
The statistical results indicated that in order to predict soil ESP based on soil SAR the linear regression model for predicting soil ESP from SAR. ESP=1.95+1.05SAR with R²=0.92 can be recommended. |
