  Soil organic matter, the National Fertilizer project required soil testing must be one of the analysis of all the determination, using oil-bath heating potassium dichromate oxidation - volumetric method in a relatively short period of time is difficult to complete the determination of 4000 soil samples task.

  To this end, Shandong Province Bureau of Agriculture Soil and Fertilizer Station Chengwu organic matter for the determination of accelerate the pace of this issue, had invited to explore laboratory personnel in ensuring the quality of laboratory tests under the premise of how to improve the testing rate as an important subject to repeated tests, study and be successful. They conventional oil bath method of innovation, developed by a consumer that can cook 96 samples digestion frame, and worked out a set of corresponding simple and quick testing methods.

  Their main innovations are: the acquisition of a Taiwan-based Instrument Co., Ltd. Jiangsu Jintan is produced by HH-Y8-type constant temperature oil bath pot, and in accordance with its specifications, its own design and processing of a digestion rack, the digestion rack 55cm long , wide 23cm, high-9.5cm, with the oil bath pot package. Digestion frame a total of 96 holes, each hole can hold a test tube (25 × 200mm), which each can hold 96 test tubes, so that digestion greatly accelerate the speed to meet the automatic zero burette filling reagent and titration, achieved the bulk of organic matter tests, rapid-oriented.

  Digestion using this framework and its testing methods matched the measurement of soil organic matter, obviously superior to the traditional conventional analysis methods, mainly reflected in:

  One is security, does not appear in the place with the sand bath, take hard tube burn-prone, with wire cage digestion difficult to control oil temperature, high incidence of fires.

  The second is accurate, with the conventional method compared to standard material test results, high accuracy.

  Third is fast, because every batch of 96 samples can be handled, combined with the automatic zero burette filling reagent and titration, three laboratory workers a day to do three batches than conventional methods for testing the speed can increase more than 5 times.

  4 is a practical, simple design of the digestion rack, reasonable, and generally at the county level can be equipped with laboratories. At present, the digestion Chengwu has been the design of aircraft and other technical declared national patent.
