Abstract: The article shows that in brown and dark gray soils distributed in the vertical soil zone of mid-altitude mountains, due to the complex geological and geomorphological structure of the surface with significant slopes and a large depth of local bases of erosion, poor anti-erosion resistance of soils and parent rocks, uneven distribution of precipitation, rainfall their nature in the spring, the absence of anti-erosion measures, erosion processes are intensively developed. Erosion processes have significantly changed the chemical and agrochemical properties of brown mountain soils that are common in the southern spurs of the Hissar Range within the confines of Surkhandarya. With an increase in the degree of erosion, the content and reserves of humus and nutrients decreased; accordingly, some agrochemical properties worsened. The article also presents the results of studies on the change in the agrochemical properties of dark gray soils of the widespread western spurs of the Chatkal ridge under the influence of erosion. Also, it is substantiated that the eroded soil under the fruit plantations has fully recovered, acquired a clearly expressed humus horizon, and an accumulation of humus and other nutrients has occurred. It is proved that terracing of slopes and planting of trees positively affect the restoration of soil fertility and contribute to the protection of soils from erosion.
Key words: Soil erosion, agrochemical properties, humus, slope exposure, slope terracing, brown carbonate soils, typical brown soils, dark gray soil.
