Description

Technical Field

[0002] The rocks on the surface of the earth are weathered and gradually broken down into loose mineral particles of varying sizes (called parent material). Soil is formed and evolved under the combined effects of multiple soil-forming factors such as parent material, climate, biology, topography, and time. The composition of soil is very complex. Generally speaking, it is composed of three phases: solid, liquid, and gas, including minerals, organic matter produced by the decomposition of plant and animal remains, water, and air. Soil environmental monitoring refers to determining the environmental quality (or degree of pollution) and its changing trends by measuring the representative values ​​of factors affecting soil environmental quality. During testing, the soil needs to be dried to remove moisture from the soil.
