Chelated Zinc EDTA is a professional-grade, 100% water-soluble micronutrient fertilizer that corrects zinc deficiency in plants. Its guaranteed analysis is 14% zinc, held as a stable EDTA chelate that keeps the zinc plant-available up to roughly pH 7.0 — well past the point where zinc sulfate begins to lock up in alkaline and calcareous soils.
Zinc is an essential micronutrient and a cofactor for enzyme systems involved in protein synthesis, carbohydrate metabolism, and growth-hormone regulation. Because zinc is immobile in plants, deficiency shows first on new growth as interveinal yellowing, small leaves, and shortened, clustered internodes. The EDTA chelate dissolves cleanly with no residue, making this product suitable for soil application, foliar correction, drip fertigation, and hydroponic systems — especially where high-pH irrigation water would precipitate ionic zinc salts.
Confirm zinc deficiency with a soil test before applying; zinc is a heavy metal that accumulates in soil, so apply only what a deficiency warrants. In hydroponics, dose from a stock solution rather than adding powder directly.
CDFA registered and third-party lab tested for heavy metals, with results consistently well below required limits.
