Description
SM Zn EDTA 15% supplies zinc, the micronutrient behind protein synthesis, gene expression, and the auxin that drives shoot extension, in a fully EDTA-chelated and plant-available form. Zinc deficiency is widespread on weathered acid soils and on calcareous soils, where the element binds to clay and carbonate and triggers shortened internodes, small leaves, and rosetting. With the entire 15% zinc content held in a soluble chelate, the product corrects these disorders directly, and it suits foliar application, fertigation, and hydroponics.
Key Benefits
- Corrects zinc deficiency in available form. It delivers zinc protected in a soluble chelate, keeping the element absorbable on the acid and calcareous soils where it would otherwise adsorb to clay or carbonate and become unavailable.
- Restores protein synthesis and shoot growth. Zinc maintains the structural stability of many enzymes, takes part in DNA and RNA metabolism, cell division, and protein synthesis, and is essential to the metabolism of the auxin indole-acetic acid that drives apical growth, so correcting it relieves stunting, little-leaf, and rosetting.
- Stays available in hard water and moderate pH. The EDTA ring keeps zinc in solution through the moderate pH range of most foliar tanks and fertigation water, resisting the precipitation that wastes non-chelated sources.
- Feeds cleanly, without unwanted salts. Because the product is free of sulphates, chlorides, and nitrates, it corrects zinc without adding the accompanying anions or salinity load that simple mineral salts carry into the root zone.
- Dissolves fast and completely. The free-flowing, dust-free micro-granules are self-soluble, dissolving without residue for reliable tank mixing and trouble-free injection.
How It Works
Micronutrient deficiency in the field is usually a problem of availability, not true scarcity. Once a metal cation such as iron, manganese, zinc, copper, magnesium, or calcium enters the soil or hard irrigation water, it reacts readily with hydroxides, carbonates, and phosphates to form compounds the root cannot absorb, so visible deficiency can appear even where the element is physically present. EDTA chelation answers this directly: the chelating agent wraps the metal in a stable ring that keeps it soluble and shields it from those reactions, holding the nutrient in a form the plant can take up. EDTA maintains this protection across moderate pH conditions, which makes it well suited to foliar sprays, hydroponic solutions, and fertigation on neutral to slightly acidic soils.
In SM Zn EDTA 15%, the full declared content of the element is chelated, so every unit applied is delivered in the available, root-ready form rather than as a simple salt that can revert to an insoluble compound. The micro-granules are fully water-soluble and dissolve cleanly without residue, and because the production route uses no sulphates, chlorides, or nitrates, the material introduces no unwanted accompanying anions into the tank or the root zone. The outcome is a clean, predictable correction in which the deficient element reaches the crop quickly, whether the aim is preventing a shortfall before symptoms emerge or correcting one already visible.
When to Use SM Zn EDTA 15%
Apply preventively on zinc-fixing soils, or correctively when shortened internodes, small leaves, or rosetting appear.
- SM Zn EDTA 15% suits early growth and establishment, when zinc demand for shoot extension is highest.
- It fits cereals and maize through early to mid season, where zinc shortage limits elongation and yield.
- It integrates into foliar and fertigation programmes on weathered acid soils and calcareous soils that immobilise zinc.
On calcareous soils zinc deficiency often coincides with iron deficiency, so confirm which element is limiting before treating, since the chelate corrects the zinc fraction rather than masking a parallel iron shortage.
Confirm compatibility with a small-scale jar test before combining with other inputs in the same tank.

Potassium Nitrate Enriched with Micronutrients 13-0-45+ME is a fully water-soluble mineral fertilizer built on potassium nitrate, delivering a high 45% K2O alongside 13% nitrate nitrogen in a single chloride-free, low-salt-index source. The nitrate form is immediately available for root uptake, and potassium itself powers the active transport of that nitrate into the root, so the […]
Monoammonium Phosphate MAP 12-61-0 is a defined mineral salt that dissociates cleanly into ammonium and dihydrogen phosphate ions, delivering a very high 61% P2O5 alongside 12% ammoniacal nitrogen in a fully water-soluble, chloride-free form. The ammonium fraction lowers pH in the immediate root zone as it nitrifies, which improves the availability of phosphorus and other […]
Monopotassium Phosphate MKP 0-52-34 is a defined mineral salt that dissociates into dihydrogen phosphate and potassium ions, delivering a high 52% P2O5 and 34% K2O with no nitrogen and no chloride. Carrying both nutrients without a nitrogen load, MKP supplies phosphorus and potassium exactly when a crop needs them most, at bloom, fruit set, and […]
NPK 30-10-10+TE concentrates its analysis on nitrogen, most of it in urea form, to fuel the rapid leaf and shoot growth of the vegetative phase. Alongside the 30% nitrogen it carries a background of phosphate and potassium, 2% magnesium (MgO) for chlorophyll, and an EDTA-chelated micronutrient package. Fully water-soluble, it dissolves to a clear solution […]
TERRA FUL is the base fulvic acid conditioner in the TERRA range, with no added rooting hormone. It carries 52% organic matter with 38% as fulvic acid and 4.5% water-soluble potassium (K2O), together with organic nitrogen in amino-acid form. Its fulvic acid and organic acids are naturally present in vinasse, a byproduct long documented as […]
