EDTA‑Fe 13%
Chelated iron • stable in pH 3–6.5 • micronutrients
Fe content
13% (typ.)
pH stability
3.0–6.5
Water insolubles
≤ 0.1%
Solubility
High (warm water speeds)
*For alkaline conditions (pH > ~7), consider Fe chelates with
higher pH stability (e.g., EDDHA). Always jar‑test mixes.

• Fertigation: prepare stock solution; inject to meet Fe
ppm targets.
• Foliar: typical 0.1–0.5% w/v; avoid hot/dry and flowering; add non‑ionic wetter if needed. • Compatibility: avoid mixing with high‑pH solutions; do not combine with calcium salts in the same tank if phosphates are present (precipitation risk). |
• 25 kg moisture‑barrier PE‑lined bags; 1 / 5 kg small
packs.
• Big bags on request; palletized & shrink‑wrapped. |
• Non‑DG. Hygroscopic—keep tightly closed; store cool/dry.
• Dissolve with warm, clean water and agitation. Jar‑test new mixes. |
Specs are representative; shipped material conforms to the COA for
the lot. For alkaline soils/waters (> pH ~7), request
higher‑stability iron chelates (e.g., EDDHA‑Fe 6%).
