Accumulation of soil organic carbon together with changes in thickness of humus and fermentation layers, pH bulk density and total phosphorus content were studied in chronosequence of 15 plot (2-41 year old) on colliery spoil heaps, overgrown by spontaneous vegetation. Heaps were formed by alkaline (pH about 8) tertiary clay material. Only scarce herb and grasses occur in sites 2-14 years old, 15-25 year old sites were covered by willow (Salix caprea) shrubs and tree (Betula sp. and Populus tremula) dominated in 25-41 year old sites. Even youngest sites contain about 4% of organic carbon. Thickness of organic soil horizons and content of carbon in mineral soil icreased during succession. Thicknes of fermentation layer peaked in 15-25 year old sires, humus layer appears on 25 year old sites and its thickness gradually increases with plot age. Accumulation of organic carbon during the first 40 years of succession in average 93 g.m.^-2year^-1.

Akumulace uhlíku v půdě byla sledována na chronosequenci patnácti neredukovaných ploch o stáří 1-41 let, zarostlých spontánní sukcesí na výsypkách po těžbě hnědého uhlí v okolí Sokolova. Průměrná rychlost akumulace půdního uhlíku na těchto plochách je asi 93 g.m.^-2rok^-1, což je porovnatelné s rychlostí akumulace půdního uhlíku v rekultivovaných olšinách na výsypkách téže oblasti.
