| Abstract: | Organic matter is a major component of soil, playing an importance role in determining the dynamic changes of soil quality. In order to be convenient to understand the advantages and limitations of current detection method of soil organic matter, and be conducive to research and develop new measurement tools for soil organic matter in the future, the article summarized the current measurement methods of soil organic matter at first, including dry combustion method, titration method, chemical oxidation, loss-on-ignition method and spectrometric method. Secondly, it analyzed the advantages and disadvantages of all methods in measuring soil organic matter and discussed which method should be selected. Next, it proposed an ideal about in-situ and nondestructive measurement tool for soil organic matter with regards to agricultural requirement and measurement method's shortcomings. Finally, the prospect of speed determination for soil organic matter is discussed in some research directions in the future. It is the aim of this paper to provide fundamental information support and proposal for precise agriculture implementation and sustainable agricultural development. |
