Product description
Product overview
Ethylenediaminetetraacetic acid magnesium-sodium salt (also known as EDTA magnesium-disodium, EDTA chelated magnesium, EDTA-Mg 6%) is a highly effective chelated magnesium product based on EDTA. The product is a white powder with chelated magnesium content 5.5%-6.5%, pH (1% aqueous solution) 6.0-7.5, water-insoluble substances ≤0.1%. Thanks to EDTA chelation technology, magnesium is in stable chelated form, allowing plants to directly absorb and utilize it.
Key characteristics
- High content of chelated magnesiumMagnesium chelate 5.5%-6.5%, ensures adequate magnesium supply.
- Good StabilityChelated Magnesium EDTA, high stability, not fixed by soil.
- Fully water-solubleFully water-soluble, no sediment, suitable for all irrigation systems.
- Low impurity contentWater-insoluble residue ≤0.1%, high purity
Application Recommendations
Recommended dosage
| Directions for Use | Recommended dosage | Important Notes |
|---|---|---|
| Foliar Feeding | 0.5-1.0 kg/hectare | Dilute 1000-2000 times, spray evenly on both sides of leaves. |
| Drip irrigation/fertigation | 5 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 performed. |
Application recommendations
- It is recommended to apply in cloudy weather or in the evening, avoiding periods of strong light and high temperatures.
- 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.
- Application frequency is adjusted according to the degree of magnesium deficiency in the crop and growth stage, typically applied every 15-20 days.
Area of application
Agricultural nutrients, fertilizers
Frequently asked questions
The main difference lies in the chelation technology and nutrient form.
- Standard magnesium fertilizerIt exists in the form of inorganic magnesium salts (e.g., magnesium sulfate, etc.), readily enters precipitation reactions with other elements, and has a low absorption rate.
- EDTA Magnesium-SodiumMagnesium is in EDTA chelated form, "encapsulated" in the EDTA molecule, has good stability, is not fixed by soil, and plants can absorb and utilize it directly.
Store in a dry, well-ventilated area, protect from direct sunlight, and handle with care.
