Application Recommendations
Recommended dosage
| Directions for Use | Recommended dosage | Safety Precautions |
|---|---|---|
| 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 pre-dissolution test must be conducted. |
Application recommendations
- Recommended to apply in cloudy weather or in the evening, avoiding periods of high heat and intense sunlight.
- Can be mixed with most pesticides and foliar fertilizers; a small preliminary test is recommended before mixing.
- When dissolving, first add the product to clean water, stir until fully dissolved, then add other fertilizers.
- Application frequency is adjusted depending on the degree of copper deficiency and crop growth stage, typically applied every 15-20 days.
Area of application
Agricultural nutrient elements, fertilizers
Used as a high-efficiency chelated copper source in fertilizers: foliar, fertigation, water-soluble, etc., for preventing and correcting copper deficiency in plants.
- Store in a dry, well-ventilated area, protected from direct sunlight.
- Stack carefully, handle with care, avoid damaging packaging.
- Protect from moisture and rain during transport
Frequently asked questions
EDTA copper sodium is a chelated copper compound with EDTA, its main differences from ordinary copper fertilizers are:
