    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.
