Rheological features of the coagulative structure of northern taiga peaty podzolic semi-gley soils of the European Northeast.

摘要

The results of rheological studies using a MCR 302 modular research rheometer of soil pastes of northern taiga peaty podzolic semi-gley soils are presented. It was found that their coagulative structure has weak structural links. They are little resistant to mechanical stress and their stability decreases in the direction from the northern to the extreme northern taiga by about two times. The strongest coagulative links between soil particles characterize the horizons with increased organic contents and the horizons that are transient in terms of granulometric composition, which lie at the border where light deposits shift heavier ones.Notes Translated from Vestnik Moskovskogo Universiteta.
