【 摘 要 】

The dynamic of industrial substrates penetration resistance changing on the recultivated field with the growing stock over a period of 42 years is shown. Forest growth conditions of industrial soils became closer to the bioecological requirements of wood and bushy species. For industrial soils formed by applying a meliorative layer 15..20 cm the soil penetration resistance falls more intensively.The control check research conducted in 2016 on embryogeny soil of chalk and marly solid showed the increase of penetration resistance in 2 times at the top layer 0.. 5 cm, at 10 cm depth - 1.6 times, at 20 cm depth - 1.4 times, at 30 cm depth - 1.3 times. The same pattern is for industrial soils with applying of chalk and marly of meliorative layer of sand, clay loam or humous soil with the yield of 40..50 cm. For industrial soils formed by applying a meliorative layer 5..10 and 15..20 cm the penetration resistance of the top edaphotopic layer was changed considerably over a period of 42 years. The most essential differences were in an industrial soil made by a sand layer 5..10, 15..20 cm, where the penetration resistance of the topsoil raised in 2.5 and 5.6 times.
