The data on influence of agrotechnical methods of cultivation of fruit and decorative crops saplings are provided in article, on physical and chemical properties of the gray forest soil. Such methods as the depth of soil preparation and a dose of fertilizer dressing were studied. It is shown that density and soil hardness in the top soil 0-20 cm didn't depend on tilling depth, in soil layer of 20-40 cm the density and hardness of the soil was significantly lower in case with tilling depth 40 cm. Therefore here the root system of saplings had bigger volume optimum on the physical indicators of a root layer. Fertilizer dressing in the raised doses promotes increase the content of nitrate nitrogen in the soil. The increase of tilling depth reduces concentration of nitrogen to 40 cm, owing to its distribution in the bigger volume of the soil.
