| Addition of solid fertilizers | 1-10% | Used as a chelating agent for micronutrients |
Application recommendations
- Shake well before use to ensure uniform solution
- Can be mixed with most water-soluble fertilizers, but a preliminary mixture test is recommended.
- Avoid direct mixing with strong alkaline substances
- Recommended storage temperature 5-35°C, avoid freezing and high temperatures.
- Specific dosage should be adjusted based on soil conditions, crop type, growth stage and local agricultural practices.
- It is recommended to test on a small area before large-scale application.
- When mixing with other fertilizers or pesticides, first conduct a compatibility test.
Frequently asked questions
Key differences:
- Chemical FormEDTA-2NH4 is the diammonium salt, while EDTA-4Na is the tetrasodium salt
- pH valueEDTA-2NH4 has a slightly acidic reaction (pH 4.6-5.2), EDTA-4Na has an alkaline reaction (pH 9.0-12.0)
- ContentEDTA-2NH4 content ≥44.7%, EDTA-4Na content ≥39%
- ApplicationEDTA-2NH4 is more suitable for agriculture and acidic fertilizer systems, EDTA-4Na is more suitable for industrial cleaning and alkaline formulations.
EDTA-2NH4 solution has the following advantages:
- Ready to useNo dissolution required, used directly, saves time and equipment.
- Good CompatibilityLiquid form is convenient for mixing with other liquid fertilizers or pesticides.
