Application Reference
Recommended Dosage
| Application Method | Recommended Dosage | Precautions |
|---|---|---|
| Foliar Spray | 0.5-1.0 kg/ha | Dilute 1000-2000 times, apply evenly to both sides of leaves. |
| Drip/Flush application | 2 kg/ha | Apply with irrigation water, avoid mixing with strongly alkaline fertilizers |
| Water-soluble fertilizer compounding | 1-3% | Pre-dissolution testing is required when combining with other micronutrients. |
Usage Suggestions
- Apply on cloudy days or in the evening, avoiding strong light and high temperature periods
- Can be mixed with most pesticides and foliar fertilizers; perform a small pre-test before mixing
- When dissolving, first add the product to clean water, stir until fully dissolved, then add other fertilizers.
- Adjust application frequency based on crop copper deficiency level and growth stage, typically applying every 15-20 days.
Applications
Agricultural Nutrients and Fertilizers
As an efficient chelated copper source, used in foliar fertilizers, drip irrigation fertilizers, water-soluble fertilizers, etc., to prevent and correct copper deficiency in crops.
- Store in a dry and ventilated warehouse, away from direct sunlight
- Stack gently, handle with care, avoid packaging damage
- Protect from moisture and rain during transport
FAQ
EDTA copper sodium is an EDTA chelate of copper; its main differences from ordinary copper fertilizers are:
- StabilityEDTA chelated copper is stable in soil and solution, not easily fixed by soil
- Absorption RateChelated copper can be directly absorbed by crops, with absorption rates much higher than ordinary inorganic copper fertilizers
- Water SolubilityEasily soluble in water, no sediment, suitable for various irrigation systems.
Store in a dry, ventilated warehouse, protect from direct sunlight, handle with care, prevent package damage.
