Abstract

The peculiarities of organic carbon water soluble fraction content in the litters and soil profile in burned forests of different age under the cryolithozone conditions have been revealed. It has been shown that surface fires cause a decrease in the content of water-extractable organic carbon (WEOC) in the litters and upper 5 cm deep layer of soil. At the same time in microelevations these differences are more pronounced and the WEOC content in the upper organogenic horizons in burnt-out places is 2 times lower. In the deeper soil horizons there have been no differences detected in the WEOC content between intact plantations and postpyrogenic areas.
