Abstract

Feature of the mountain soil formation is that the soil on the mountain slopes are formed in differentbioclimatic and oro-geomorphologic condition and soil conditions are characterized by high contrast and variation.The features of the morphological structure, a truncated profile (35-75 cm), weakly expression in the differentiationof the soil profile into individual horizons, and a detritus (20-65 %), loamy fine layer, the signs of podzolization inthe soil profile is not found, despite the presence of spruce - fir forest’ acid litter. Perhaps the high content of totaliron is the cause of the lack of morphological demonstration of the podzolic process. The coefficient of the eluvialilluvialmigration of Al2O3 and Fe2O3 (R2O3) shows the lack of trend, a weak decrease in the genetic component ofthe horizon relative to the class. Soils are characterized by a very acidic environment and high hydrolytic acidity,which was affected by exchange aluminum. The soils of mountain-taiga zone are enriched in organic matter, andhumus profile characterized by prolixity, which is a feature of mountain soils. The investigated soils were specific,as they can find closer to the brown forest and podzolic type of soils. These soils were unique in terms of soil formation.
