Abstract
Six forest locations were chosen from urban (U) and semi-urban (SU) zones of Sofia, Bulgaria. Soil profiles characterised for their generic physico-chemical properties: particle size distribution, pH, C-content (%) and N-content (%). From the ratio silt/clay and C/N, significant differences were observed for the Ah horizon in the urban and semi-urban locations. Clay formation appeared to be reduced in this horizon in the urban soils and the C-content is higher in semi-urban soils in comparison with the urban soils. On the base of the results obtained, a reduction of the buffering capability is noted for the topsoil of the urban sites compared to the semi-urban sites.
