The paper presents generalized results of studies of the influence of forest reclamation impact on changes in the agrochemical properties of soils in arid areas of the Uil district of Aktobe region. Field work was carried out in July-August 2021. It has been established that on dark chestnut soils in the BC horizon, an increase in easily soluble salts and sulfates is observed, where the amount of salts varies from 0,89 to 0,39%. The use of forest reclamation techniques helps to reduce the content of sulfates by 0,61%, reduce soil pH to 7,8. Studies of the content of soil organic matter have shown that its highest concentration is observed on virgin lands and on soils under forest plantations. This is due to a decrease in the anthropogenic load and the positive impact of the forest belt, which acts as a barrier. The use of forest reclamation techniques on dark chestnut soils of the Uil district of the Aktobe region contributes to the accumulation of humus, changes in the reaction of the soil solution and improves the water-physical properties of the soil.

Key words: soil, arid zone, forest reclamation, chemical and physical properties of soils, Uil district of the Aktobe region, Kazakhstan.
