This article is devoted to assessing the enzymatic activity of irrigated soils in the Surkhandarya region under the possible influence of the Tajik Aluminium Company. During the study, the activities of the enzymes urease, invertase, and catalase were determined under laboratory conditions and analyzed at points located at different distances. The results showed that enzyme activity was lower in areas close to the industrial source and increased with distance. This was explained by the high content of fluoride compounds in the soil and processes of ecological degradation. The study demonstrated that enzyme activity can be effectively used as a bioindicator for assessing soil biological activity and pollution levels. Based on this, it is recommended to regularly conduct enzyme analysis for monitoring and restoring contaminated soils.
