Product description
Product overview
Calcium disodium ethylenediaminetetraacetate (EDTA-CaNa₂), formula C₁₀H₁₂N₂O₈CaNa₂·2H₂O, molecular weight 410.3, CAS 23411-34-9. White powder, chelated calcium content 9.5-10.5%, pH 6.5-7.5. Produced using advanced EDTA chelation technology, calcium is in chelated form, ensuring direct uptake by plants and significantly higher efficiency compared to conventional inorganic calcium fertilizers.
Key Advantages
- High StabilityChelated calcium EDTA remains stable in soil and solution, not prone to precipitation.
- Fully water-solubleWhite powder, fully water-soluble, suitable for various irrigation systems.
- High bioavailabilityCalcium is in chelated form and can be directly absorbed by plants.
- Good SafetypH 6.5-7.5, near neutral, safe for crops.
- Low impurity contentWater-insoluble substances ≤0.1%, high purity.

Application Recommendations
Recommended dosage
| Field of Application | Recommended dosage | Instruction |
|---|---|---|
| Foliar fertilizer | 0.05-0.2% | Foliar application for rapid calcium replenishment |
| Drip irrigation/fertigation | 5 kg/ha | Adjust according to the crop's calcium requirement. |
| Mixing water-soluble fertilizers | 5-15% | Addition as a source of mesonutrients |
| Base fertilizer | 20 kg/ha | Mix with base fertilizer |
Application recommendations
- Foliar spraying is recommended in cloudy weather or in the evening on a clear day, avoiding periods of high temperature.
- Can be mixed with most water-soluble fertilizers, but compatibility testing is recommended beforehand.
- Avoid direct mixing with strongly alkaline substances.
- When dissolving, it is recommended to use warm water to speed up the process.
- Specific dosage should be adjusted based on soil conditions, crop type, growth stage, and local agricultural practices.
- It is recommended to conduct a test on a small area before large-scale application.
- Calcium replenishment should be carried out in advance to prevent deficiency symptoms.
