| Abstract: | Abstracts:Based on the standard LY/T 1237-1999 (determination of organic matter in forest soil and calculation of carbon nitrogen ratio), this paper determined the organic matter contents by the method of potassium dichromate heating oxidation volumetric. We analyzed and discussed the main influence factors on determining result. Furthermore, some solutions were proposed to guarantee the testing analysis accuracy on forest soil sample and enhance the test efficiency. |
