    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.

    The studies were conducted on the former arable land, intensively used, designated for extending the collection of Dendrological Garden in Przelewice. This area is characterised by a low wavy relief with gentle slopes of ca 3%, on average. Study results showed great variations, especially vertical, in granulometric composition and a considerable diversity of soil types, which had been greatly affected by water erosion. The investigated area was found to be dominated by leached black earth, grey-brown podsolic soil and deluvial soils. Considerably smaller areas were covered with rusty soils, grey-brown soils and arenosols. Irrespective of the soil type classification, these soils are characterised by a substantial humus horizon, mostly sandy clay or loamy sand containing from 4 to 6% clay fraction (<0.002 mm). Reaction is predominantly slightly acid to alkaline, humus content from 10.0 to 30.0 (mean 17.3) g · kg–1, bulk density from 1.22 to 1.59 (mean 1.47) Mg · m–3 and total porosity from 38.8 to 52.2 (mean 43.1) %. Among the determined types of soils, the most beneficial morphological characteristics and properties were detected in leached black earths.

    This paper is the continuation of the first part of research assessing the suitability of former, intensively used, arable land for the extension of Dendrological Garden collection in Przelewice presented in “Morphological characteristics and some physical properties of soils” Despite a fairly stable loam fraction (<0.002 mm) in the humus horizon (Ap), the examined soils differed in organic carbon content, reaction and total exchangeable acidity, which differentiated their sorptivity (T) and extent of saturation with alkaline cations (V). It was found that in Ap horizon of grey-brown podsolic soil T was 6.9 cmol(+) kg–1 and V only 58.0%, in Ap of deluvial soils T ranged from 9.3–17.5 cmol(+) kg–1, and V 58.1–97.1%, whereas in leached black earths T was in the range 12.6–17.9 cmol(+) kg–1 and V 81.0–89.9%. Resources of available potassium and phosphorus varied from low to very high while the resources of available magnesium were medium. In light of legal regulations and recommendations the soils did not exhibit heavy metal contamination. Due to a high value of trophicity indicator ITGL (from 33.9 to 44.8), they were classified as eutrophic and hypertrophic.
