Two methods of far-infrared graphite furnace heating and boiling water bath heating used to detect soil organic matter and to test the precision, significant difference and the accuracy of them. The standard deviation (SD) of two methods were less than 1.2, the coefficient of variation (CV) were less than 4%. Two methods have no significant difference. Sample recoveries were in the 95%-105%. They were all meet experimental testing requirements. At the same time, the two methods were high efficiency and safety and environmental protection compared with oil bath, suitable for fast batch testing.
