THE ECOLOGICAL PECULIARITIES OF THE SOIL-FORMATION AND THE DIAGRAM OF BIOLOGICAL RECULTIVATION IN THE EXTREME NORTH OF RUSSIA

The purpose of the work: studying the peculiarities of tundra soils; revealing the role of the seasonal freezing as the main factor for the humus-formation in tundra; developing the ecologically justified methods of the agricultural use of the tundra grounds and methods of accelerated restoration of zonal types of biogeocenoses on the technogenous territories. Used have been the lysimetric method, modelling by the original method of the Author, and the methods of the stationary field investigations. For the first time, the justification of the ecological high instability of the tundra biogeocenoses to the technological effect and its slow self-restoration has been given. First, the characteristic of the humus-formation processes in tundra in the ecological aspect with the prolonged effect of the frozen factor taken into account, the methods of the agricultural use of the tundra grounds and the conception of biological recultivation has been given. Introduced and productively used under the conditions of the Extreme North has been the method of tinning as the optimum method of the agricultutal use of the tundra grounds for the purposes of food-production.
