[0002] Soil sampling refers to collecting representative soil samples according to scientific methods for analyzing their physical, chemical or biological properties. It is an important foundation work in the fields of environmental monitoring, agricultural research, land assessment, etc. Before sampling, the purpose needs to be clarified, the sampling point layout needs to be reasonably planned, and the surface impurities need to be removed using clean tools. Then, the sample is collected according to the required depth, mixed uniformly, and divided into an appropriate amount. The sample needs to be sealed from light, labeled with information such as time, location, and depth, and stored at low temperature to prevent deterioration. Standard soil sampling can ensure accurate test data and provide reliable basis for soil remediation and planting optimization.
