SM Mn EDTA 13%

SM Mn EDTA 13% supplies manganese, an enzyme cofactor the plant needs in small but non-negotiable amounts, in a fully EDTA-chelated and immediately available form. Manganese is most often deficient on leached, sandy, or high-pH soils where it converts to forms roots cannot reach, producing interveinal chlorosis on younger leaves and greyish patches on the older leaves of cereals. Holding the entire 13% manganese content in a soluble chelate, the product delivers the element where the crop can use it, and it fits foliar sprays, fertigation, and hydroponic feeding.

Key Benefits

• Corrects manganese deficiency in available form. It delivers manganese protected in a soluble chelate, reaching the plant in an absorbable form rather than converting to the unavailable oxides that leave younger leaves chlorotic.
• Drives the plant’s enzyme systems. Manganese activates around thirty-five enzymes across the tricarboxylic acid cycle, decarboxylation, and redox reactions, contributes to the oxygen-evolving step of photosynthesis, and forms part of manganese superoxide dismutase that shields tissue from oxidative damage, so correcting a shortfall restores this activity in new growth and roots.
• Stays available in hard water and moderate pH. The EDTA ring keeps manganese 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 manganese 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 Mn EDTA 13%, 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 Mn EDTA 13%

Apply preventively on soils known to fix manganese, or correctively when interveinal chlorosis appears on younger leaves.

• SM Mn EDTA 13% suits early vegetative growth, when new leaves first show manganese-deficiency chlorosis.
• It fits cereals from tillering through stem extension, where manganese supports photosynthesis and lignification.
• It integrates into foliar and fertigation programmes on leached, sandy, peaty, or high-pH soils that hold little available manganese.

Manganese availability falls sharply on highly leached tropical soils and on soils derived from manganese-poor parent material, so the chelated form matters most where the soil cannot resupply the element on its own.
