Applicable Conditions:
Soil pH range: 4.5–9.0 (the higher the pH, the more pronounced the advantage of EDDHA chelated iron over EDTA chelated iron and ferrous sulfate).
Suitable crops: Peach trees, kiwifruit, grapes, jujube trees, citrus, bananas, and other iron-deficient crops.
Application Methods:
Foliar Spray:
Spray concentration:
Flowers/vegetables: 50–100 g/acre (0.05%–0.1% solution)
Fruit trees: 30 g/acre (maximum concentration 0.1%)
Spray frequency: Once per week; iron deficiency symptoms improve significantly after 2–3 consecutive applications.
Optimal timing: Spray on cloudy days or during early morning/late evening; reapply if rain occurs within 4 hours after spraying.
Flushing/Drip Irrigation:
Compatible with other micronutrient fertilizers, pesticides, and soluble phosphate fertilizers.
Hydroponic nutrient solution: 1 ppm iron fertilizer solution (17 g EDDHA-Fe 6% per 1 m³ water).
Fertilizer Additive:
Suitable for producing foliar fertilizers, flush fertilizers, drip irrigation fertilizers, water-soluble fertilizers, organic fertilizers, and compound fertilizers.
Packaging: 25 kg/kraft paper bag
Storage: Store sealed in a cool, dry, and dark place
Wear appropriate protective equipment during handling. Avoid inhalation and direct contact with skin or eyes. In case of contact, rinse immediately with plenty of water.
