- High StabilityEDTA chelated copper remains stable in soil and solution.
- Fully water-solubleBlue powder, fully water-soluble, dissolves quickly, suitable for various irrigation systems
- High bioavailabilityCopper is present in chelated form, ensuring direct uptake by crops
- Low impurity contentWater-insoluble substances ≤0.1%, high purity.
Application Recommendations
Recommended dosage
| Application method | Recommended dosage | Important Notes |
|---|---|---|
| Foliar Feeding | 0.5-1.0 kg/ha | Dilute 1000-2000 times, spray evenly on both sides of leaves |
| Drip irrigation/fertigation | 1-2 kg/ha | Apply with irrigation water, avoid mixing with strongly alkaline fertilizers. |
| Mixing water-soluble fertilizers | 1-3% | When used together with other micronutrients, a preliminary solubility test is required. |
Application recommendations
- Recommended to apply on cloudy days or in the evening, avoiding periods of strong light and high temperature.
- Can be mixed with most pesticides and foliar fertilizers; it is recommended to conduct a small preliminary test before mixing.
- When dissolving, first add the product to clean water, stir until fully dissolved, then add other fertilizers.
- Adjust application frequency according to the crop's copper deficiency level and growth stage; typically apply every 15-20 days.
