Chelated Zinc EDTA is a water-soluble micronutrient fertilizer that contains zinc (Zn) chemically bound to EDTA (Ethylenediaminetetraacetic acid), a chelating agent. This binding process forms a stable complex that prevents zinc from reacting with other elements in the soil, enhancing its availability to plants. It typically contains 12% elemental zinc and is highly effective in correcting zinc deficiencies in crops.
