1, acidity meter: used to determine the pH of soil.
2. Conductivity meter: used to measure the conductivity in soil and indicate the content of dissolved salt in soil.
3. Atomic absorption spectrometer (AAS): used to determine the concentration of trace elements in soil, such as iron, manganese and zinc.
4. Infrared spectrometer: By measuring the absorption of infrared radiation by soil samples, the contents of organic matter and inorganic matter in soil can be analyzed.
5. Spectral radiometer: used to measure the radiation flux of soil to understand the changes of heat and moisture in soil.
6.x-ray diffractometer (XRD): It is used to analyze the mineral composition in the soil and get the information of soil type and composition.
7. Chromatograph: used to separate and analyze organic and inorganic substances in soil, and can detect chemical substances in soil.
8. Gas chromatography-mass spectrometry (GC-MS): used to analyze organic pollutants in soil, such as pesticides and organic solvent residues.
9. Moisture meter: Soil moisture is also an important indicator of soil and is closely related to plant growth. Understanding the change of soil moisture can not only effectively prevent natural disasters such as drought, but also accurately guide agricultural irrigation and optimize agricultural water use.
10. Rapid soil nutrient tester: Soil nutrient is the most concerned soil index in agricultural planting field. The level of soil nutrients not only reflects soil fertility, but also is closely related to the quality of agricultural production.
Study the role of soil components
1. Understanding soil fertility: The analysis of soil components can provide information about nutrient content in soil, such as organic matter, nitrogen, phosphorus and potassium.
2. Hidden danger assessment: By studying the soil composition, we can assess whether there are potential environmental pollution and soil degradation problems in the soil.
3. Soil improvement and fertilization: Studying soil composition can guide the choice of soil improvement measures, such as adding organic matter and improving soil structure.
4. Soil selection and crop planting: By analyzing soil composition, we can understand soil types and characteristics, and then choose crops suitable for planting.
5. Soil protection and management: Studying soil composition can evaluate soil health and quality, thus guiding soil protection and sustainable soil management.
