ترجمة الملخص

A field experiment was carried out in Al-mrya'aiah Station (Dier Ezzor governorate ) for five years (2003-2008) where five rates of were added (36,72,108, 144 and 180 ton\h ) to control treatment (without addition).The objective of the study was to determine the residual effect of on soil for the depths (0-25, 25-50, and 50-75 cm) and corn plant after five years of its application.The results changes in most of the physical and chemical characters of the soil.with increasing the application rate of , where the bulk density decreased and the porosity increased in addition to the structure coefficient and the degree of aggregation, while the dispersion coefficient decreased in addition to the electric conductivity of the soil. the content of of of soluble chloride deceased. On the other hand fertility characteristic such as the mineral nitrogen loss was decreased while the content phosphor was increased and that was associated with a decrease in organic matter and significant increase in corn productivity with increase in the application rate of .The study of the residual effect of some heavy elements (Cu,Zn,Cd,Pb ) showed significance increases in there in soil ,but in corn plant, just (Cu, Zn ) showed significant increases. However, these increases were within the allowable normal limits, ditto this study showed significant increases in the total and soluble fluoride concentrations in soil and plant. This increases were within the allowable limits justin the plant.
