Product Introduction
Product Overview
Calcium Disodium EDTA (EDTA-CaNa₂), molecular 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 exists in chelated form for direct crop uptake, with absorption far exceeding ordinary inorganic calcium fertilizers.
Core Advantages
- High StabilityEDTA chelated calcium is stable in soil and solution and is not prone to precipitation.
- Fully Water-SolubleWhite powder, fully water-soluble, suitable for all irrigation systems
- High Absorption RateCalcium in chelated form, directly absorbable by crops
- Good SafetypH 6.5-7.5, near neutral, crop-friendly
- Low impuritiesWater insoluble matter ≤0.1%, high purity

Usage Recommendations
- Foliar application is best done on cloudy days or in the evening to avoid high temperatures
- Can be mixed with most water-soluble fertilizers, but a pre-mix test is recommended
- Avoid direct mixing with strongly alkaline substances.
- Use warm water during dissolution to speed up the process.
- The specific dosage should be adjusted based on soil conditions, crop type, growth stage, and local agricultural practices.
- Conduct small-scale trials before large-scale use.
- Calcium application should be done in advance to prevent deficiency symptoms.

FAQ
EDTA-CaNa₂ is an EDTA chelated calcium fertilizer, with the main differences from ordinary calcium fertilizers:
- StabilityEDTA chelated calcium is stable in soil and solution, and is not prone to form precipitates with phosphates.
- Absorption RateChelated calcium can be directly absorbed by crops, with an absorption rate far higher than that of ordinary inorganic calcium fertilizers.
- Water SolubilityFully water-soluble, no sediment, suitable for all irrigation systems
