The degree of turfy soil decomposition is the relative proportion that animal and plant residues decomposed by soil microbes account for and its special structures also lead to high content of organic matter. The decomposition degree and organic matter content of turfy soil can not only reflect the degree of peatification in the soil forming environment, but also influence the engineering and physical properties of turfy soil. The improved test method for organic matter and decomposition degree of turfy soil were studied and then applied to the samples collected from Dunhua and Jingyu in China. The results showed the simpleness and convenience of the amended method and the organic matter content and decomposition degree varied from different soil layers. The surface and bottom layer shared high decomposition degree but low oragnic matter content which was on the contrary to the middle part. And the comparison showed that there was some differences in organic matter content between the former method and amended method.
