Provide soil environmental testing
Soil environmental monitoring is to determine the environmental quality (or pollution degree) and its changing trend by measuring the representative values of the factors affecting soil environmental quality. Soil monitoring usually refers to soil environmental monitoring, which generally includes sampling, sample preparation, analytical methods, result characterization, data statistics and quality evaluation and other technical contents.
Composition of the soil
The rocks on the Earth's surface are gradually broken down into loose mineral particles of different sizes (called parent material) by weathering. Soil is formed and evolved under the comprehensive action of parent material, climate, biology, topography, time and other soil-forming factors. The composition of soil is very complex. Generally speaking, it is composed of solid, liquid and gas phases, such as minerals, organic matter produced by decomposition of animal and plant residues, water and air.

Soil other indicators: PH, chloride, phosphate, water-soluble salt, cation exchange capacity, fluoride, etc.
2. Certification services
The test report issued by Global Zhongyi has legal effect and can be used in scenarios such as the entry of supermarkets, product appeals, anti-malicious rights protection, and auctions (appeals and auctions must meet Party A's testing requirements).
