Abstract
The lab experiment carried out in the college of agriculture – University of Baghdad in Abu – Ghrib Province for study Calicum , Magnesium and Sodium in Sodiumbehavour in the Silt loam texture Soil. The Calicume , Magnesiume and Sodium were added to the soil with Potassium Sulphate (K 41%) as Source for Potassium to the above Soil in five Concentration (0 , 50 , 100 , 150 , 200) ppm. The results showed thatthesolube and exchangeable Potassiume this rate has differed to the applied cation , where it was 1.11% of the soluble state of and E treatments , while the increase rate of in the exchengablestae was differed due to the applied cation where it was 18.72% between C and A treatment , while the rate was 13.74% between C and E treatmeant was 4.38% between Aand E treatmeant. Results also showed that the values of binding energy of Potassium (k) was , arelativeiy decreased and there was an increase in binding energy whenSodium was added other than other cations. Results also showed that the impact of Calcium binding energy of potassium was higher than Magnesium. Also, salts mixture added to the values of potassium binding energy in the soil was cleariy effected. Effects were different depening calcium gave the highest binding energy. Results showed that control treatment gave highest valuesexchang surfaces, while when ions added separately, treatment A which contain calcium salts 100% gave highest potassium ion adsorption values compared with other salts treatments, increase rates of the applidionswas differed where it was 55.55% between A and C treatmeant and 300% between C and E treatmeant while it was 157.14% between E and A treatmeant. Ion mixture effect on the maximum values of adsorption showed that control treatment was the highest, followed by 50% calcium cation of treatment B. The results also showed that there was a clear effect on increasing the percentage of saturation with potassium when calciumand magnesium ions added other than sodium ions , they increased in different rates due to the applied ion at (30.5 , 14.77 , 13.69) of (A and C , A and E , and C and E) respectively.
