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.

Service project:

1. Testing standard

Soil testing:
Soil fertility index detection: organic matter, total nitrogen, total phosphorus, total potassium, nitrate nitrogen, ammonium nitrogen, available phosphorus, available potassium, slow potassium, moderate elements (calcium, magnesium, sulfur, silicon), trace elements (copper, iron, manganese, zinc, boron, molybdenum);
Soil pollution detection: heavy metals (lead, arsenic, cadmium, chromium, mercury, nickel, cobalt, vanadium, thallium, antimony and beryllium), pesticide residues and other organic pollutants (organochlorine pesticides, organophosphorus pesticide and carbamate pesticides, polycyclic aromatic hydrocarbons, phenolic compounds, nitrobenzene compounds, aniline compounds, such as phthalic acid, etc.);
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).
