The water-physical properties (bulk density, air conductivity, texture, water content, and temperature dynamics) were studied in a chronosequence of soils developing on self-overgrowing quarry-dump complexes in the area of Sokolov, Czechia. The area overgrown for 12 years was covered by a thin grass cover; osiers were observed after 20 years of overgrowth; a broadleaved forest was found on a plot after 45 years of overgrowth. The particle-size distribution in the soil was determined using peptization by pyrophosphate and the FAO method. When the soil was prepared by the FAO method, a predominance of physical clay (62-72%) in the dump material was revealed; at the use of pyrophosphate peptization, the content of this fraction was lower (18-19%). The observed differences can be due to the incomplete degradation of the microaggregates composed of clay particles during the peptization by pyrophosphate.
