Abstract

The detailed analysis of the results obtained in the course of experimental studying of the tundra soils in Western and Central Siberia and in the European part of Russia has revealed the general regularities of the variability and the relationships between the agrochemical and other properties of the soils. On the basis of these data, the calculated methods for the assessment of a complex of agrochemical properties of natural and disturbed tundra soils under different moisture and thermal conditions were elaborated. Among the properties analyzed, the following are important for plant growth: the acidity and the content of humus, organic carbon, total nitrogen, mobile phosphorus, nitrogen, and potassium. The relationships between the soil agro-chemical properties and the plant productivity allowed applying them for the quantitative evaluation of the environmental threat of the soil-plant cover’s degradation because of different predominantly mechanical disturbances.
