Was carried out this study to demonstrate the possibility of mixing physical contaminated soils soils clean in solving oil pollution in the soil problem by estimating some vital activities of soil microbes . been implemented experience pots with a capacity of 6 kg of mixture dirt composed of soil and river sand by (1:3) (Sand: Soil) and then mixed soils pots at different rates from the soil of crude oil contaminated (see 0.20 % and 30% .40 %.50 %) and the seeds sown barley by / 30 / seed per potted and has laboratory microbiological chemical and vital time in three stages and was The mixing ratio of 20% contaminated soil , as well as the ratio of 30% seen in the results of this experiment concentrations doped for prepared bacteria and fungi in soil considered mixing ratio of 40 %, 50% ratios inhibitor of bacterial growth and mushrooms, and the ability of fungi to decompose over time even focus a 40% measurable actinomays have proved instrumental in the reclamation of contaminated soil and grew up in the mixing ratios of 40% and 50 % and this is an important conclusion future Any physical reclamation can be used directly in the soil in order to reclamation and purification . And Co2 measurement showed an accumulation of quantity despite the decline in the number of microbes in the majority of concentrations and this is due to the decomposition of the oil compounds remained constant, which led to the accumulation of Co2 in the soil. As phenols are formed in the soils experience steadily with increasing mixing ratios and significant differences were statistically significant compared with witness. 

Key word : oil pollution , physical mixing, measuring Co2, total phenols , indole acetic

جرى تنفيذ هذه الدراسة لبيان إمكانية الخلط الفيزيائي للترب الملوثة بالترب النظيفة في حل مشكلة التلوث النفطي في التربة من خلال تقدير بعض الأنشطة الحيوية لميكروبات التربة. إذ تم تنفيذ تجربة أصص بسعة 6كغ من خلطة ترابية مكونة من التراب والرمل النهري بنسبة (1:3) (Sand:Soil) ثم خلطت ترب الأصص بنسب مختلفة من تربة ملوثة
