This study was carried out to demonstrate the possibility of physical mixing contaminated soils by estimating some vital activities of soil microbes. There has been implemented pots experience with a capacity of 6 kg of mixture dirt composed of soil and river sand by (1:3) (Sand: Soil) and then soils' pots were mixed at different rates from a crude oil contaminated soil (see 0.20 % and 30%.40 %.50%) and the seeds sown barley by / 30 / seed per pot and microbiological, chemical, and vital laboratory in three time phases and the mixing ratio was 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% inhibitor ratios of bacterial growth and mushrooms, and the ability of fungi to decompose over time even the condensation 40% for measurement. The Actinomays have proved an instrumental role in the reclamation of contaminated soil and grew up even in the mixing ratios of 40% and 50 % and this is an important future conclusion for physical reclamation. For it can be used directly in the soil for the purpose of reclamation and purification. As phenols are steadily formed in the soils of the experience with the increase of the mixing ratios and significant differences were statistically significant compared with witness. An additional concentration on Indole Acetic acid, unlike henols with increased mixing ratios.

جرى تنفيذ هذه الدراسة لبيان امكانية  الخلط الفيزيائي للترب الملوثة بالترب  النظيفة في حل مشكلة التلوث النفطي في التربة خلال تقدير بعض الانشطة الحيوية لميكروبات التربة .اذ 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 بالنفط الخام )شاهد ,%20و %30,%40,%50) وزرعت بذور بالشعير بواقع /30/ بذرة في الأصيص  الواحد وتمت التحاليل المكروبيولوجية الكيميائية والحيوية في ثلاث مراحل زمنية وكان النتائج كما يلي :
