The properties of the anthropic soils formed at the sludge bed “Třinec-Jahodná”. The sludge bed came from a long-time depositing of fly-ash and slag layers. Therefore, the anthropic soil properties obtained their features by both a character of layered substrate and a management of the local land reclamation. The paper presented deals with the rate of an intensity of biological and biochemical soil processes in charge of the fulfilment of plant nourishment demands, and the time viewpoints focusing on the local soil development. The set of enzymatic and biological measurements were chosen for treatments of soil bodies sampled throughout 2007–2008. The study plots inside the sludge bed and the control plot were sampled; the properties of particular horizons were studied. The results proved that the twenty-year-development of soil bodies made the proper conditions for plant nutrition. The positive statement, nevertheless, is directly linked to the presence of trees and shrubs. The vegetation seems to be one of the very crucial factors for a status of the site and maintenance of soil productivity: it affects temperature amplitudes, sensitivity to erosion, a redistribution of soil water, and a humic compounds accumulation. The statistical analyses showed significantly differing results on the study plots with a shorter development and a lower rate of vegetational cover.
