Iron deficiency, or iron chlorosis, is a common problem in calcareous and alkaline soils where iron becomes “locked” and unavailable to plants. The result is yellowing leaves and stunted growth. For high-value crops like citrus, grapes, and berries, EDDHA Fe 6% is the most effective solution.
Unlike EDTA or iron sulfate, which lose stability in high-pH environments, EDDHA (Ethylenediamine-N,N’-bis(2-hydroxyphenylacetic acid)) remains stable even in soils with a pH above 7.0. KHUMIC’s EDDHA Fe 6% provides a steady supply of ortho-ortho iron, which is the most active form for plant uptake. A single soil application can correct iron deficiency for an entire growing season, ensuring vibrant green foliage and maximum photosynthetic efficiency.
