Abstrakt
One method of improving the conditions for growth and development of urban trees is
the use of stone and soil mixtures called structural soils. Studies provided by various authors
indicate that beside the salinity the main factor of trees decaying is excessive soil compaction
and lack of appropriate water-air relations.The aim of the research was to determine the basic
physical parameters of two structural soils: Hydralit ZN – Baustoffe GmbH, Baumsubstrat and
Hydralit ZU – Baustoffe GmbH, Baumsubstrat's Tegra. The study showed that the structural soil
Hydralit ZN is classified as a very strong skeletal soil and skeletal-sandy. This structural soil is
characterized by the bulk density of 1.37–1.46 g · cm–3, the total volumetric water capacity
35.4–37.7% capillary water capacity 25.49–30.16% and air porosity 5.22–10.71%. The second
of the analyzed structural soil – Hydralit ZU, consists mainly of gravel, which was attributed to
the very skeletal. It is characterized by high total porosity 35.39–40.61%, non-capillary porosity –
9.80–17.53% and capillary porosity – 22.53–27.58%. The physical properties of both substrates
ensure correct water-air properties and mechanical ones for proper rooting and growth of trees.
