Аннотация:Previously Albic Retisols were believed to be the dominant soil group
under taiga forests. However, the studies in Western and Eastern Siberia
showed the presence of various loamy soils both with and without textural
differentiation. There are Cambisols and Cryosols with specific caviar and
cryoplaty structures, Fe-Mn nodules and coatings. We hypothesized that differentiated
and poorly differentiated soils form due to local hydrothermal,
topographical and lithological conditions. As a result of divergent evolution
the diversity of the studied soils was higher than expected previously.
