KINETICS OF IMMOBILIZATION AND MINERALIZATION OF NITROGEN POOL'S FORMATION IN CRYOARID AND PERMAFROST SOILS: THE EFFECT OF MICROBIAL POOL’S ACTIVITY AND FUNDAMENTAL LAWS OF THERMODYNAMICS

On the basis of long-term researches in micro-field experiments with 15N and involving statisticians and mathematical model simulations it was provided a detailed panorama of kinetic characteristics of nitrogen transformation in soil-formation processes of immobilization - mineralization due to the effect of different demonstrations of kinetic activity by the representatives of microbial cenosis of arid and permafrost soils as a reflection of the fundamental law of thermodynamics and Le Chatelier's principle in a particular display. As a result, the specific nature of these kinetic displays (k) in the formation of such a highly dynamic nitrogen pool in soils, regardless of their fertility, provides a dynamic stability of the functioning of nitrogen immobilization and mineralization, ensuring the maintenance of the nitrogen status of soils and replenishment with available nitrogen at any moment of time (t). Such assessment enables to identify an algorithm of predictive scenarios of in-soil nitrogen transformations for the soils of various productivity with the prospect for creation of a digital supporter.
