The results of the comparative analysis of physical, chemical and biological characteristics of the soil cover at the sites of the first stage of the proton launch vehicle (LV) fall in the Yu-2 zone (Central Kazakhstan) are presented.Conclusions are made about the increased sensitivity of the microflora of brown, mostly solonetzic soils to mechanical and chemical loads during the fall of the separating parts of space rockets.Lack of moisture, increased carbonate content and density of saline in the upper horizons complicate the restoration of the disturbed fertile soil layer even 10 years after the impact of rocket and space activities (SRA).
