An approach to access urban soils’ spatial variability at the local level

Abstract

There is still lack of clear information on the urban soils mainly because of their extremely high spatial variability. In this study we analyzed the specific features of urban soils’ spatial variability at the local level (64 ha plot; 126 sampling points). Four contrast urban soil sub-types were distinguished in the study area: primitive urban soils on the technogenic parent material, grey-humus soils with urbopedogenensis features, urbanozems and urban soil on the layers of sewage accumulation. Comparison between the results of regional and local analysis did not show the trend of spatial variability decrease as a result of detailed elaboration. Thus it may be concluded that high spatial variability is an integral feature of urban soils, that assumes principally different approach for their spatial analysis
