EDTA Chelates

EDTA is the standard, cost-effective chelating agent, stable and plant-available up to roughly pH 6.5–7.5. Above that — in calcareous or alkaline soils common across parts of West Asia and North Africa — EDTA-bound iron in particular drops out of solution and becomes unavailable, which is the specific reason higher-stability chelates like EDDHA exist as a separate, more expensive product category rather than a premium version of the same thing.

11 products are listed in this category: 6 in the Gold tier and 5 in the Platinum tier. Gold-tier formulations are specified by composition; Platinum-tier products are field-ready blends. The range covers EDTA Zn, EDTA Mn, EDTA Fe, EDTA Cu, EDTA Ca, EDTA 4Na, EDTA 2Na, Manganese EDTA 13%, EDTA-MgNa₂ (Magnesium Chelate), EDTA-CaNa₂ (Calcium Chelate), EDTA-MnNa₂ (Manganese Chelate). Pack sizes listed for these products: 1 kg, 2 kg, 5 kg, 10 kg, 25 kg. Each product page gives its specifications and packaging, and controlled copies of the TDS and SDS are supplied for the requested market and formulation.

Part of the Chelated Micronutrients range. Chelation surrounds metal nutrients (Fe, Zn, Mn, Cu, Ca, Mg) with protective organic molecules, keeping them fully soluble and plant-available across a wide range of soil pH levels to ensure effective nutrient delivery.

GoldChelated Micronutrients

EDTA Zn

Zinc bound to EDTA, the standard synthetic chelating agent, keeping zinc plant-available in solution up to roughly pH 6.5-7.5 rather than precipitating out as it would in an unchelated salt. Zinc deficiency shows first in new growth as shortened internodes and interveinal chlorosis ("little leaf"), a common issue in high-pH or high-phosphorus soils that lock up free zinc. Chelation gives more reliable foliar and fertigation uptake than sulfate forms under those conditions.

GoldChelated Micronutrients

EDTA Mn

Manganese bound to EDTA, keeping the nutrient in plant-available form for foliar or fertigation delivery up to roughly pH 6.5-7.5. Manganese deficiency appears as interveinal chlorosis on middle-to-young leaves, most common on high-pH or poorly aerated soils where manganese becomes chemically unavailable regardless of total soil content. Chelation avoids the fixation that limits sulfate-form manganese in those same conditions.

GoldChelated Micronutrients

EDTA Fe

Iron bound to EDTA, the most common and cost-effective iron chelate, stable and plant-available up to roughly pH 6.5 — the classic correction for iron chlorosis, which shows as interveinal yellowing in the youngest leaves since iron is nearly immobile within the plant. EDTA-Fe is the standard first choice for moderate-pH soils; above pH 6.5-7 its stability drops off sharply, which is where DTPA- or EDDHA-chelated iron becomes necessary instead.

EDTA Cu

Copper bound to EDTA, keeping the nutrient plant-available for foliar or fertigation delivery up to roughly pH 6.5-7.5. Copper deficiency shows as dieback and distorted new growth, particularly in high-organic-matter or sandy soils with naturally low copper reserves. Chelation prevents the antagonism copper otherwise shows with phosphorus and iron uptake when applied as a simple salt.

PlatinumChelated Micronutrients

EDTA Ca

Calcium bound to EDTA, the standard synthetic chelating agent, stable and plant-available up to roughly pH 6.5-7.5. Because calcium moves through the plant almost entirely in the xylem and barely at all in the phloem, tissues furthest from the water stream — fruit tips, inner leaves, new growth — are the first to show deficiency even when soil calcium is adequate. EDTA chelation keeps the calcium in plant-available form for foliar or fertigation delivery to those tissues, with stronger chelating capacity than amino-acid-carried alternatives, though it is subject to the same upper pH stability limit as other EDTA-chelated nutrients.
