Abstract

This study examines washed-out ordinary mountain black soils located in the mid-mountain belt of the Pirsaatchay river basin. These areas currently retain characteristics of a forest landscape. The objective of the research was to conduct a comparative assessment of soil-ecological changes over the past 60–70 years based on an analysis of the soils’ physicochemical properties. The findings indicate that these processes have progressed rapidly under the combined influence of natural and anthropogenic factors. Owing to the dense vegetation cover and favorable hydrothermal conditions during the autumn and spring seasons, a high rate of organic matter restoration is observed. However, this process slows down during dry years. The organic matter content decreases with depth in the soil profile, primarily due to the vertical movement of the soil solution. At present, these soils are utilized in various branches of agricultural production.
