SM Cu EDTA 15%

SM Cu EDTA 15% supplies copper, a highly active redox metal the plant needs for lignified cell walls and fertile pollen, in a fully EDTA-chelated and available form. Copper takes part in photosynthesis, respiration, and carbon and nitrogen metabolism, and its shortage shows as distorted young leaves, twisted stems, poor pollen, and reduced seed-set. By delivering its full 15% copper content in a soluble chelate, the product corrects the deficiency cleanly, and it fits foliar, fertigation, and hydroponic programmes.

Key Benefits

• Corrects copper deficiency in available form. It delivers copper protected in a soluble chelate, reaching the plant in an absorbable form on the organic and leached soils where copper is most often locked up.
• Supports redox metabolism, structure, and fertility. Copper drives redox reactions in photosynthesis and respiration, is essential to the lignification that strengthens xylem and stems, and underpins pollen formation and seed-set, so correcting it restores both structural integrity and reproductive performance.
• Stays available in hard water and moderate pH. The EDTA ring keeps copper 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 copper 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 Cu 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 Cu EDTA 15%

Apply preventively on copper-poor soils, or correctively when young leaves distort and stems twist.

• SM Cu EDTA 15% suits early vegetative growth, especially on organic, peaty, or leached soils where copper is scarce.
• It fits cereals and field crops ahead of flowering, when copper supports pollen formation and seed-set.
• It integrates into foliar and fertigation programmes as a controlled copper source.

Copper is needed in small amounts and the margin between sufficiency and excess is narrow, so the chelated form supports accurate, low-dose correction rather than broad soil loading.
