Iron deficiency, commonly known as iron chlorosis, is a persistent challenge in calcareous and alkaline soils, where vital iron becomes “locked” and biologically unavailable to plants. This condition manifests as characteristic yellowing leaves and stunted growth, severely impacting the health and productivity of high-value crops like citrus, grapes, and berries. For professional growers facing high-pH soil conditions, KHUMIC’s EDDHA Fe 6% is the most robust and effective solution available.
Unlike EDTA or traditional iron sulfate, which rapidly lose stability in high-pH environments, EDDHA (Ethylenediamine-N,N’-bis(2-hydroxyphenylacetic acid)) remains exceptionally stable and effective even in soils with a pH above 7.0. KHUMIC’s premium EDDHA Fe 6% provides a consistent supply of ortho-ortho iron, the most biologically active and effective isomer for plant uptake. This high-purity chelated iron ensures that iron remains available to the root system, preventing nutrient lockout and promoting vigorous growth.
A single soil application of our EDDHA Fe 6% can effectively correct and prevent iron deficiency for an entire growing season. By ensuring vibrant green foliage and maximizing photosynthetic efficiency, KHUMIC helps growers achieve superior fruit quality and higher marketable yields, making it an indispensable component of modern, high-performance fertilization programs.
