Cechy morfologiczne i właściwości chemiczne gleb przykrytych nawierzchnią bitumiczną (ekranosoli) w obrębie ulicy Obronców Stalingradu w Szczecinie
MetadataShow full item record
Szczecin soils, especially in its historical, oldest parts, like the soils in other cities are either built-up or covered with various materials reducing or blocking water percolation capacity and gas exchange. According to Polish Soil Classification, such soils belong to anthropogenic, urban soils, sealed or covered; hence the term ekranic soils. The profile of soil covered with bituminous surface within the street Obrońców Stalingradu in Szczecin had the following characteristics: bituminous surface – stone pavement – Ca – 2Ca – 3C. Strongly transformed, anthropogenic soil material under the street surface contained 48.1% soil skeleton, on average, among which there were 54.8% of anthropogenic artifacts. Smaller amounts of artifacts (mean 24.0%) occurred also in deeper layers of the profile. The examined ekranosols were characterised by alkaline reaction, CaCO3 content in the range 3.8–4.8%, very low salinity, trace amounts of organic carbon, decreasing with depth, in the layer Ca wide C:N ratio (mean 21.8), low resources of available potassium and magnesium, medium to high resources of available phosphorus with its low total content. The content of Cd, Pb, Zn, Ni, Co and Mn was at a low, natural level. Only the level of Cu was elevated (I degree of contamination).
