This study investigated the effect of erosion processes on enzymatic activity in brown and gray soils of the mountainous and foothill regions of the Western Tien Shan. During the study, the activities of invertase, catalase, and amylase enzymes were determined and compared in soils washed to different degrees. The results showed that with increasing erosion, the biological activity of the soil decreases, especially the activity of the invertase enzyme decreases sharply. While the amylase enzyme is relatively stable, it was found that catalase activity varies depending on the type of soil and environmental conditions. It was proved that enzymatic activity indicators are important bioindicators in assessing the biological fertility and ecological state of the soil. The results obtained are of great importance in assessing the fertility of eroded soils in mountainous and foothill regions and developing scientific and practical recommendations for their protection.
