Abstract: Soil samples were collected from a cement plant in the city of Xuzhou (Jiangsu Province, China), and the soils black carbon (BC) and organic matter (OM) are analyzed  in this study. The results show the mean BC and OM in soils are 12.35 g/kg and 112.33 g/kg, respectively. The forest soil BC and OM contents have both significantly positive  correlations with frequency magnetic susceptibility(χfd) (p < 0.001), whereas the farmland soil BC and OM contents exhibit both significantly negative correlations with  frequency magnetic susceptibility (p < 0.001). The findings indicate the soils BC and OM are quite different in different soil types, and human activities greatly influence on  the soils chemical properties. The BC contents in various soil types consistently have significantly positive correlations with magnetic susceptibility (χ), the susceptibility  of anhysteretic remanent magnetization (χARM), saturation isothermal remanent magnetization (SIRM) and soft isothermal remanent magnetization (SOFT). The soils OMs have  significantly positive correlations with χ, SIRM, and SOFT. This study suggests that these magnetic parameters (χ, SIRM, and SOFT) can be used in soil analysis instead of BC 
and OM contents.
