| Abstract: | The content of organic matter in soil was determined with the method of potassium bichromate-dilution heat colorimetric. The recovery rate was 95.2%~108.2% and the CV was 2.67 %~3.68 %. The results showed that this method was convenient operation, fast, low-cost and time-saving and meanwhile, can reduce the environmental pollution and dispel the hazard in the experiment. The sensitivity and accuracy of this method accorded with the request of soil analysis. |
