Overview
EDDHA Iron is a synthetic iron chelate widely used in agriculture to address iron deficiency in plants. It is particularly effective in alkaline soils where iron availability is limited. The compound is derived from the chelation of iron with EDDHA (Ethylenediamine-N,N'-bis(2-hydroxyphenylacetic acid)), ensuring high stability and bioavailability. EDDHA Iron is favored for its ability to remain soluble and effective across a broad pH range, making it suitable for various soil conditions. It is commonly applied as a soil amendment or foliar spray to crops such as citrus, grapes, and ornamentals, which are highly susceptible to iron chlorosis.
Physical and Chemical Properties
EDDHA Iron appears as a dark brown to black powder or granules, highly soluble in water. Its molecular formula is C18H16N2O6Fe, with a molecular weight of 436.18 g/mol. The chelate is stable under a wide range of pH conditions (3-11), which distinguishes it from other iron fertilizers like EDTA Iron, which loses effectiveness in alkaline soils. The compound’s high solubility ensures rapid uptake by plants, while its stability prevents precipitation in soil. These properties make EDDHA Iron a reliable solution for long-term iron supplementation in challenging agricultural environments.
Main Applications
EDDHA Iron is primarily used in agriculture to correct iron deficiency in crops, a condition known as iron chlorosis. Symptoms include yellowing leaves with green veins, stunted growth, and reduced yields. It is applied through soil drenching, irrigation systems, or foliar sprays, depending on the crop and severity of deficiency. This chelate is especially valuable for high-value crops like citrus fruits, grapes, and strawberries, which are prone to iron deficiency in calcareous soils. It is also used in horticulture for ornamental plants and turfgrass, ensuring vibrant foliage and healthy growth.
Safety and Storage
EDDHA Iron is generally safe when handled properly, but precautions are necessary to avoid health risks. Workers should wear gloves, goggles, and masks to prevent skin contact, eye irritation, or inhalation of dust. In case of exposure, rinse affected areas with plenty of water and seek medical advice if irritation persists. Storage recommendations include keeping the product in a cool, dry place, away from direct sunlight and moisture. Containers should be tightly sealed to prevent degradation. Proper storage ensures the product’s efficacy and longevity, maintaining its chelation properties over time.
B2B Procurement Guide
When procuring EDDHA Iron for agricultural use, buyers should prioritize purity and chelation percentage. High-quality products typically contain 6% iron by weight, with at least 90% of the chelate in the ortho-ortho isomer form, which is the most effective for plant uptake. Supplier reliability is critical; look for certifications like ISO or OMRI (for organic farming). Bulk purchases may offer cost savings, but verify storage conditions and shelf life. Prices vary based on purity and market demand, ranging approximately $20-$50 per kg. Always request technical data sheets and batch analysis reports to ensure compliance with agricultural standards.
