Abstract
Humus profiles of soil in Siberia under different conditions and models of soil formation are considered. It is shown that the humus profiles of soil formed in the regions of shifts of landscape and soil borders and developing according to the polygenetic model, as well as the soils of syn-lithogenous type of pedogenesis, have a complicated structure. Simple structure of the humus profile characterizes the kinds of soil developing within the framework of a simple (ideal, normal) model of soil formation.
