The assessment of humus state of soils of natural ecosystems of the main soil and geographical zones of Kuzbass

The research goal is to evaluate the current soil humus condition within the limit of monitoring base stations (BS), associated with the primary industrial regions of Kuzbass. The tasks are to study the contents and general volume of organic substance; particularities of qualitative composition and basic parameters of soil humus state. BS characterize a certain zone: forest-steppe of Kuznetsk Depression, insular forest-steppe, steppe core of Kuznetsk Depression, the zone of foothill forest-steppe, Mariinsk-Achinsk soil district of segmented forest-steppe and the forest-steppe of foothills. The soils of BS are related to texture-differentiated and accumulative-humus soils of post-lithogenous shafts. For researched sod-podzolic soils as well as for all West-Siberian podzolic soils of some retardation and non-compensated circulation of biological substance is characteristic, thereby the average level of organic substance humification (29-30 %), low level of humus volume and poor enrichment with nitrogen...
