The article presents the results of the study of the oilcontaminated sandy loam soil of the town of Balykchy of the Kyrgyz Republic before and after bioremediation. The changes in the structure and composition of the soil have been established. In particular, the soil is noticeably dispersed, and the pH of the soil after bioremediation decreases slightly. The content of CO₂ and humus during bioremediation decreases by 5.8 and 30.7 %, while the mobile form of phosphorus (P₂O₅) and exchangeable potassium (K₂O) after bioremediation increase, respectively, by 32.0 and 93.3 %. In soil there are succession phenomena that are expressed in a change in the dominance of individual microorganisms actively functioning in the soil. The long term of soil contamination with oil products leads to the predominance of bacteria using organic and mineral forms of nitrogen, and even compared to the background indicators, their number is much higher.
