    The studies included initial industrisols (ecranic) on the peninsula Ewa in Szczecin port. Samples of these soils were collected from deep boreholes (to 13 m below ground level), whereas those of humus soils from the topsoil 0–25(30 cm) of sporadically occurring lawns. Port infrastructure did not allow sampling deeper strata. In stratigraphic structure of initial ekranosols, the surface layer, 2.7–4.4 m thick (mean 3.20 m) of sand, transported to improve the swampy terrain under construction, was distinguished. Transported material, obtained from dredging the nearby water bodies contributed to the compaction of Holocene formations (organic deposits and fen peat), visible at the depth 3.20–9.00 m. This sandy cover layer, under reinforced concrete slabs, contained 2–5% fraction <0.002 mm and only in its upper part, skeleton fractions of anthropogenic origin. It was characterised by pHKCl 5.7–8.0), a slight to 1% CaCO3 content, mean 7.0 g · kg–1 content of organic carbon and wide C : N 17.5 : 1 ratio, whereas the predominant organic layer of examined boreholes had pHKCl 4.9–6.7, organic carbon in the range 174.1–183.7 g · kg–1 and the ratio of C : N from 13.5 : 1 to 16.7 : 1. Comparison of topsoil properties of initial industrisols (ekranic) of thickness 0.25–1.50 m, with humus soils under squares, confirms the common origin of these sandy soil materials. Humus soils also contained 3–6% fraction <0.002 mm, similar reaction and CaCO3 content. Increased, in these soils, content of organic carbon to 28.6 g · kg–1 and in some cases even to 86.6 g · kg–1, and total nitrogen from 2.2 to 8.9 g · kg–1 resulted in a more beneficial ratio of C : N from 9.7 : 1 to 13.0 : 1. High accumulation of organic carbon and available phosphorus, potassium, and magnesium is, first of all, the effect of fertilisation and cultivation practices. The analysis of these properties shows how important role, in the ecosystem of urban and industrial-urban soils, is played by land utilisation, which is becoming a vital soil-forming factor.
