Sixty surface (0-25 cm) soil samples (compound and noninvestor) were chosen from soils of Deir Ezzor province, the soil samples were ranged between medium content of CaCO3 and moderate pH to high content of CaCO3 with low to medium pH. The results showed that:

There was a positive correlation with high significant between clay % and available zinc and phosphorus (0.65 and 0.74, respectively) and there was a significant correlation between O.M. % and available zinc and phosphorus (0.44 and 0.55, respectively).

There was a positive correlation with high significant between pH and available phosphorus (0.64) and a significant correlation between pH and available zinc (0.58).

There was a significant correlation (negative) between available zinc and phosphorus and EC in soil that medium in CaCO3 % and moderate in pH (-0.37 and -0.42, respectively).

There was a negative correlation with high significant between CaCO3 % and available phosphorus and zinc (-0.68 and - 0.81, respectively), and a significant correlation (negative) between pH

and EC with phosphorus and zinc in soils that high content of CaCO3 and low to medium of pH.

There was significant correlation (positive) between available phosphorus and available zinc (0.49) in tested soils.

Key words: Soil properties- phosphorus- zinc.

تم اختيار /60/ عينة ترابية مركبة بكرية على عمق/0-25/ سم من أراضي محافظة دير الزور. وكانت عينات التربة تنتمي للترب ذات المحتوي المتوسط من كربونات الكالسيوم والمعتدلة الحموضة، و إلى الترب العالية المحتوى من كربونات الكالسيوم والقليلة والمتوسطة القلوية، وبعد تقدير نسبة الطين، وبعض المؤشرات الكيميائية والخصوبية في العينات الترابية المدروسة توصلنا إلى النتائج التالية:
