Physicochemical and chemical parameters of soils in the Central district of St.-Petersburg: content of organic carbon, group composition of humus, C/N ratios, pH in water suspension, color coefficient of humic acids (E465/E650), calcyte content and particle size distribution are considered. High variability of the most part of parameters was emphasized. It was affected by different regime of exploitation, presence or absence of vegetation and traffic influence. The difference of urbanozem from zonal podzol soil is probably caused by the presence of nonspecific organic compounds in the first one.
