To provide a simple test method for the degree of decomposition in highly organic soil, instead of a phon post method, capable of more quantitatively accurately determining the degree of decomposition in the high organic soil in a sampling site of a sample by reducing the occurrence of large variations and errors in determination results.
In the simple test method for determining the degree of decomposition in the high organic soil in the sampling site of the sample 10, the sampled sample is wrapped by gauze 11 of size for wrapping a handful of samples 10, moisture contained in the sample 10 of high organic soil is leached by twisting the wrapped part 12, to color the gauze 11 with the leached water, it is compared with a color sample made of previously sampled samples of a plurality of highly organic soils of different degrees of decomposition and corresponds to the degree of decomposition in the highly organic soil of the leached water coloring the gauze 11, and the separation degree of the sampled sample 10 of high organic soil is determined.
