Introduction
Interpretation of GB/T 36207—2018 Silicon Calcium Potassium Magnesium Fertilizer Standard
I. Background and Significance of Standard Formulation
Silicon Calcium Potassium Magnesium Fertilizer is an important soil conditioner and fertilizer, and its main components include water-soluble and citric acid-soluble silicon, calcium, potassium, magnesium and other elements. The formulation of GB/T 36207—2018 standard aims to regulate the production, inspection and application of silicon calcium potassium magnesium fertilizer to ensure that the product quality meets the requirements of agricultural production and environmental protection.
II. Scope of Application of the Standard
This standard applies to products made from insoluble potassium ore and raw materials containing calcium and magnesium through high-temperature conversion. Its main features include:
- Contains a variety of secondary elements and beneficial elements
- Has the function of improving acidic soil
- Can be used as a supplement to compound fertilizer
III. Comparison of standard framework and technical requirements
| Item | Indicator classification | |
|---|---|---|
| Silicon (Si) content/% | 9.0 | 6.0 |
| Calcium (Ca) content/% | 20.0 | 14.0 |
| Potassium (K₂O) content/% | 3.0 | |
| Magnesium (Mg) content/% | 2.0 | |
IV. Recommendations for the implementation of the standard
1. Quality management:Manufacturers should strictly carry out quality control in accordance with the requirements of the standard to ensure that the products meet the key indicators specified in Table 1.
2. Safety measures:When testing the silicon content, it is necessary to pay attention to the strong corrosiveness of hydrofluoric acid and take personal protection measures.
3. Application recommendations:Silicon-calcium-potassium-magnesium fertilizers are suitable for improving acidic soils and are recommended to be used in combination with macronutrient fertilizers.
