- Good StabilityEDTA chelated iron, high stability, not fixed by soil
- Readily solubleEasily soluble in water, convenient to use, suitable for various water-soluble fertilizer formulations.
- Low impurity contentWater-insoluble substances ≤0.1%, high purity
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. |
| Complex water-soluble fertilizer | 1-3% | When used together with other micronutrients, a preliminary solubility test is required |
Application recommendations
- It is recommended to apply in cloudy weather or in the evening, avoiding periods of strong light and high temperature.
- Compatible with most pesticides and foliar fertilizers; a small preliminary compatibility 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 according to the degree of iron deficiency and crop growth stage; typically applied every 15-20 days.
Area of application
Agricultural nutrients, fertilizers
Used as a high-efficiency chelated iron source in foliar fertilizers, fertigation, and water-soluble fertilizers to prevent and correct iron deficiency symptoms in plants.
Food additive
As a food additive for iron enrichment, used in the food industry and for dietary supplements.
Desulfurization
Used as an auxiliary agent in industrial desulfurization processes.
- Store in a dry, well-ventilated area, protected from direct sunlight.

- Protect from moisture and rain during transportation
Frequently asked questions
EDTA iron chelate (sodium salt) is an iron chelate compound with EDTA, the main differences from ordinary iron fertilizers are:
- StabilityEDTA chelated iron is stable in soil and solution, less prone to soil fixation.
- Absorption CoefficientChelated iron can be absorbed directly by plants, with a significantly higher utilization rate than conventional inorganic iron fertilizers.
- Water SolubilityEasily soluble in water, no sediment, suitable for various irrigation systems
