Description :
This study aims to improve our understanding of urban soil organic carbon (SOC) in comparison with agricultural and natural areas for the Moscow region (Russia). SOC content was studied in different land use types, soils, and urban zones through stratified random sampling. SOC contents were significantly higher in urban areas compared with non-urban areas. Further analyses proved that the difference can be explained by the so-called cultural layer, which is the result of human residential activity and settlement history. SOC contents in the urban environment presented a very high spatial heterogeneity with standard deviations of urban SOC considerably higher than those for agricultural and natural areas. It is concluded that urban SOC should not be ignored in regional and global carbon assessments.
