A Comparative Study on Magnetic Susceptibility of Cinnamon Soil and Brown Soil in Pingyi County, Shandong Province, China

Magnetic susceptibility is the most commonly used soil magnetic parameters, reflecting the degree of magnetization substance. The investigation of two typical soil sections in Pingyi County, Shandong Province shows that there are some differences on magnetic susceptibility between the cinnamon soil profile and the brown soil profile. The results indicate that: (1) Significant difference of magnetic properties is existed among the cinnamon soil profile and the brown soil profile. The mean χlfvalue of the samples from the cinnamon soil profile is 82.80×10-8m3/kg, distinctly lower than those from the brown soil profile, which have a mean value of 616.72×10-8 m3/kg; (2) This indicates a low proportion of SP in samples from the brown soil profile and a high proportion of SP in samples from the cinnamon soil profile; (3) Magnetic susceptibility features is a new method which can be used for soil preliminary classification.
