Chelated Manganese EDTA Fertilizer

Chelated Manganese EDTA is a 100% water-soluble micronutrient fertilizer that corrects manganese deficiency in plants. Its guaranteed analysis is 13% chelated manganese, held as a stable EDTA complex that keeps the manganese plant-available from pH 4.0 to 7.0 — the range where sulfate forms rapidly oxidize and become unavailable in soil.

Manganese is an essential micronutrient central to photosynthesis and active in dozens of plant enzyme systems. Because manganese deficiency typically appears as interveinal chlorosis on middle-aged leaves, a tissue or soil test is the best way to confirm it before treating. The EDTA chelate dissolves cleanly with no residue, making this product suitable for foliar correction, soil and field application, drip fertigation, turf, and hydroponic systems — and it is the preferred manganese form for tank-mixing with glyphosate.

For foliar use, spray in early morning or late afternoon, keep rates modest, and repeat as needed until new growth greens up. Do not exceed recommended rates: excess manganese can be harmful to sensitive crops and can interfere with iron uptake.
