The objective of this study was to compare soil organic matter contents determined by oxidation method (Tyurin) and dry combustion method. A total of 238 soil samples were collected across an agricultural region originated from granite, limestone, volcanic ash soils. Results showed that soil organic matter content by dry combustion method for granite and limestone-derived soils was 1.09 - 1.12 times higher than that of Tyurin method, and 1.24 times higher for volcanic ash-derived soil. A significant linear relationship was found between Tyurin method and dry combustion method. The coefficients of determination (R²) between two method for granite, limestone, and volcanic ash soils were 0.984<SUP>***</SUP>, 0.847<SUP>***</SUP>, and 0.997<SUP>***</SUP>, respectively. Soil organic matter contents on Tyurin method with respect to dry combustion method varied between 70% and 82%. There was no significant difference between two methods for paddy, upland, and plastic film house soils among granite derived soils. Therefore, dry combustion method using regression equations could be converted effectively to measurement value of Tyurin method. Using automatic dry combustion method, it may be possible to analyze soil organic matter content cost effectively by reducing labor input.
