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.plUznanie autorstwa-Użycie niekomercyjne 3.0 Polskamieszanka kamienno-glebowategrawłaściwości fizycznezastosowanie w terenach miejskichphysical propertiesstructural soilused in urban areasDyscyplina::Nauki rolnicze::Rolnictwo i ogrodnictwoArticle
