In recent periods, urban soils have been extensively studied. These studies contribute to better understanding of the soil cover diversity in the urban area, identification of changes and threats resulting from expansion of urbanization and industrialization. The aim of our study is to identify to define correctly some urban soils, such as “technogenic soils”, that are recently introduced in the soil classification and are constantly updated and completed. The studied sites are located in the urban areas from northeastern part of Romania. In our studies we made several soil profiles. The studied soils have been diagnosed according to the Romanian System of Soil Taxonomy and World Reference Base for Soil Resource. Characterization of soil profiles was done following the instructions from guidelines for soil and land descriptions. The urban soils are characterized by a strong spatial heterogeneity resulting from various input of exogenous materials and mixing of material from different soil horizons. Case studies conducted in several locations of urban areas showed that Ekranic and Linic Technosols keeps some undisturbed soil properties such as particle size, mineralogical composition and allows some plants roots to develop their roots. We believe that the results obtained during our investigations will facilitate easier identification in the field of urban soils such as Linic and Ekranic Technosols and the establishment of appropriate management.
