- It is recommended to conduct small-scale tests before large-scale use
- When mixing with other fertilizers or pesticides, first perform a compatibility test
FAQ
Key Differences:
- Chemical FormEDTA-2NH4 is a diammonium salt, EDTA-4Na is a tetrasodium salt
- pH ValueEDTA-2NH4 is weakly acidic (pH 4.6-5.2), EDTA-4Na is alkaline (pH 9.0-12.0)
- ContentEDTA-2NH4 content ≥44.7%, EDTA-4Na content ≥39%
- ApplicationsEDTA-2NH4 is more suitable for agricultural and acidic fertilizer systems, EDTA-4Na is more suitable for industrial cleaning and alkaline formulations.
