Organic matter inn soils of toposequences in the southern taiga subzone( as examplified by soils of the Central Forest Reserve)

摘要

Organic matter was studied in soils forming two toposequences noted for different drainage conditions in the southern taiga subzone. Changes in the content, profile distribution and storages of organic carbon and nitrogen as well as inn group and fractional composition of soil humus have fractional composition of soil humus have been examined as related to the degree of hydromorphism.
