The research was conducted in 2021-2025 on the basis of I.A. Bunin Yelets State University under the conditions of model experience. In terms of physical parameters, dark gray forest soil turned out to be more moisture-intensive and hygroscopic than sod-podzolic soil. According to agrochemical indicators, dark gray forest soil differed from sod-podzolic soil in more favorable properties: less acidic reaction of the medium, more humus, total nitrogen, mobile phosphorus, exchangeable potassium and especially exchangeable calcium - 2.5 times. By the 4th year of growth, the appearance of a young apple seedling of the Boiken variety showed that growth was faster on dark gray forest soil. The 4-year-old apple seedlings grown on dark gray forest soil were significantly taller, had a larger stem diameter, and a longer length of annual terminal growths. The number of leaves per 1 terminal apple tree growth and the average leaf area did not depend on the type of forest soil. The water retention capacity of the leaves of apple seedlings grown on dark gray forest soil was significantly higher than that of plants grown on sod-podzolic soil. The water content in the leaves of the seedlings was significantly higher in plants grown on dark gray forest soil.
