تقويم السلوك الحركي لتأثير القوة الأيونية لمياه الري على كاربونات الكالسيوم باعتماد معادلتي الانتشار و الرتبة الأولى

الملخص EN

The study was conducted to know the Physiochemical behavior of carbonate, Laboratory study was made by choosing three different sites from Middle Euphrates soils which were Najaf, Al-Escandariya , and Abo Gharak .

The chosen was made based on the difference in percentage of carbonates which were 120,280, 380 gm.Kg-1 respectively.

These soils are used with three types of irrigation water where each type has different ionic strength which was 0.01, 0.11, 0.21 ml and the values of SAR were 0.65, 2.5, 8.3 for three types of water which were well water, river water, and drainage water respectively.

These different water are added to different soils for ten weeks (70 days),free calcium was calculated from each week in the three soils treated with three water qwahities had different ionic strength.Many motional equations are implemented for describing the motional behavior of free item from the soil, some of these equation from the difference between the free item Ions concetrition, and its concentration in said dissolution.the another equation it the first step equation which means the speed of the free item which Precipitate with the rest amonunt of the soil Solid phase .After substitute these two equation ,the best equation will be chosen by calculated the highest limit item(R2) and the Less standard Error(SE)which ware calculation by the Statistical analysis and by calculate the factor of dissolution speed for each motioual equation and the difference between the soils.
