GROWING OAK ON THE SLOPING LANDS OF THE CENTRAL FOREST-STEPPE

Abstract

The scientific research on growing English oak on eroded soils was carried out in order to prevent erosion processes. The object of the research was a land plot on washed-out gray soils of the network and hydrographic funds. Oak crops are laid by row-well sowing of acorns of 3-5 pieces or more in one planting place. As a result of many years of research, it was revealed that during the growth period, the rootsystem of the oak binds the washed-out slope soils well. The resulting forest litter improves the structureof the soil and increases its moisture capacity to 322% of the dry matter. The forest suitability of soils on eroded slope lands allows you to grow protective plantings from oak culture. At the age of 50, oak stands with the number of trees of 1730 pcs./ha on eroded soils have a reserve of 160 cubic meters/ha with an average height of 12.5 m and an average diameter of 13.6 cm. The average increase per 1 ha is 3.20 cubic meters/ha. Oak stands on the hydrographic network have a class III bonus. The growth of oak is noticeably improved in the presence of an admixture of other hardwoods, especially linden and undergrowth of hazel, mountain ash, birch bark, yellow acacia and other shrubs. Studies have shown that oak crops can be successfully grown on washed-out slope soils which reliably protect the soil from water erosion.
