Soil environmental testing refers to determining the environmental quality (or degree of pollution) and its changing trend by measuring the representative values ​​of factors affecting soil environmental quality. When testing soil, it is first necessary to obtain soil samples. The distribution of pollutants in the soil has both horizontal differences caused by the distance from the pollution source and vertical differences caused by time and other factors.

When the sampled soil is taken out from the sampler, soils of different depths will be mixed together, resulting in inaccurate test data and increasing the difficulty of soil testing; 3.
