Аннотация:Particularities of some biological cycling indexes and humus condition indexes dynamic due
to natural post-agrogenic re-afforestation in south taiga were studied. By post-agrogenic
succession, total plant biomass in ecosystems increases due to tree stand renewal, biomass growth
rate by arable land overgrowing exceeding biomass growth rate by hayfield overgrowing.
Total carbon stock in ecosystems increases by post-agrogenic re-afforestation mainly due to
perennial plant parts. The part of soil carbon, conversely, decreases in spite of absolutely
increasing. Especially clearly, carbon accumulation takes place in overgrowing arable land, formed
on sandy soil. For overgrowing arable land, essential increasing content and stock of carbon in
topsoil is observed. For overgrowing hayfield, decreasing these indexes is observed on initial stage
of succession. The particularities of organic carbon content and stock post-agrogenic dynamic
depends on soil reclamation history, vegetation dynamic and native soil features, including soil
texture.
