[0002] Soil sampling refers to the method of collecting soil samples, including the layout and sampling techniques of the samples. The sampling tools are usually soil drills, shovels, samplers, etc. Different sampling methods can be selected according to the research requirements and the characteristics of the plot, such as diagonal method, plum blossom method, chessboard method or snake method. When sampling, the soil depth and sampling volume should be uniform, and the ratio of the upper and lower layers of the soil should be the same. The sampler should be inserted vertically into the ground and at the same depth.

[0003] Existing soil sampling is usually completed using a soil drill.
