The evaluation methodology is based on the use of mathematical models of the trend component processes for the humus horizon and humus accumulation development in Forest-Steppe Black Earth areas. In postagrogenic soils of Central Black Earth region of Russia the rate of carbon assimilation with regenerating soils varies from 21.00-71.30 g C m–2 per year, depending on the degree of violation. The highest rate of carbon fixation in an organic matter is typical for postagrogenic soils with severely degraded humus horizon in which the relative content of humus is in the range of 1-3.5%.
