ABSTRACT: This paper presents results of long-term model, greenhouse and microfield experiments on nitrogen transformation in soil-plant systems with application of stable nitrogen isotope (15N) as renewed efforts to make a biokinetic conception of nitrogen status in harsh climates of the northern part of Central Asia, namely in Transbaikalia. It uses a theory to investigate velocity characteristics of nitrogen pool change in cryogenic soil environments. The goal of theoretical background of nitrogen pool velocity transformation is to reveal modern approach to assessment of inherent nature cycle. In nitrogen cycle of soil-plant systems kinetic parameters were evaluated as the main processes of nitrogen 15N uptake and immobilization in terms of scaling with constant of growth velocity and microorganism performance being a key position in nitrogen transformation. The results show a new possibility to assess nitrogen cycle through calculated velocity constant and revealed dynamic pattern of the main processes. The ongoing assessment enables us to formulate a new original hypothesis for theoretical kinetical model.
