FEATURES OF REHABILITATION OF TECHNO-PYROGENIC DISTURBED MEADOWS IN THE NORTHEAST OF RUSSIA
Sowing of perennial grasses and their mixtures has been shown to be effective in rehabilitating disturbed meadows located in the cryolite zone of the central and eastern parts of Baikal-Amur Railroad (BAR). On the pyrogenic soils was determined the optimal layer of fertile peat-ash ground applied to soil, fertilizer doses, and seeding rates for grasses and grass mixtures. Biological rehabilitation of disturbed natural meadows and return of them to economical using is the most important way to conserve land resources and to sustain the ecological balance in the territory of BAR, where natural and cultural landscapes undergo considerable technical impacts on the part of extractive and processing industries at mining operations. When burning wood waste at lumbering places, at casual handling with fire, as well as spontaneously on drained peat lands in dry years, there occur fires resulting in vast areas of pyrogenic peat burned-out areas. The methods of biological rehabilitation allow us to considerably increase productivity of disturbed grasslands and to involve them in agricultural turnover.
