There were significant differences of soil organic matter in different soil types and regions. The average content of organic matter in different soil types was as follows: skeleton soil > red soil > lime soil > paddy soil > alluvial soil > seashore saline soil. The average content of organic matter in different regions was as follows: water net plain > low hill > valley plain > coastal plain.
