Organic matter is one of the important indexes of soil testing, and also an important index to measure soil fertility. The different heating methods in the potassium dichromate volumetric method were compared and analyzed, and the detection method of soil organic matter was improved. It is found that the constant temperature electric heating method is controllable, the result precision is high, the detection result is consistent with the standard testing method, and the fast batch inspection can be realized.
