The Effect of Moisture Distribution on the Differentiation of the Cryometamorphic Soils Profile

Abstract

In this research investigation is loamy soils. Cryometamorphic division is diagnosed according to the Classification and Diagnostics of Soils of Russia or Luvisolic Souls according to WRB. These soils are formed on uplands, uvals, in conditions of good drainage. However, the eluvial process is difficult and there is practically no podzolic horizon in the soil profile. Earlier research attributed the weak differentiation of the soil profile to low temperatures and prolonged soil freezing. With the help of trigonometric levelling of the relief surface, automatic monitoring system for temperatures, soil humidity, as well as methods that study the hydrological regime of soils, it was revealed that the soils of the cryometamorphic department have unsatisfactory water permeability of soil. Meltwater rolls down the slope, forming a stagnant hydrological regime in the runnels, contributing to peat accumulation. A differentiated profile forms on the slopes. Lateral water movements along the slope carry iron oxides, fine material and form an eluvial horizon. The lower cryometamorphic horizons do not currently freeze, but their formation has been influenced by permafrost processes in the past. As a result of pulling hygroscopic moisture and thin mineral quartz grains to the freezing front, skeletans were formed on the surfaces of pedas. Coatings are formed on the surface of the units at a depth of 1 m. Moisture in the soil is an important factor for the formation of soils with a differentiated profile and an undifferentiated profile. Soil moisture monitoring is important to describe the regulatory growing functions of valuable conifers such as Pinus sibirica and Picea obovate.
