Maxwell Bullet Chelated Iron (7%) 5L

Whilst other products often describe themselves as chelated, Bullet Chelated Iron is a 100% chelated iron. Furthermore, it is formulated from 100% carboxylic acid using our in-house technology. The chelated formula prevents ‘lock-up’ with other elements in soils and significantly reduces the incidence of iron oxidization which can lead to soil panning.

Maxwell Bullet Chelated Iron 5L

Over the decades it has been claimed that plants fertilised with iron will produce thicker cell walls that protect against stress and pathogens. This is not the case, and in fact acidic iron sulphate products will act to strip plant cell walls of calcium leading to a weakening. Instead Bullet Chelated Iron uses a pH neutral chelated iron that is not acidic and thus protects the cell wall from degradation.

Further to this, Bullet Chelated Iron has been formulated to protect the epidermal cells and associated beneficial microbes from harmful ultra violet radiation; this means that there is a strong biological protection in place against pest and disease attack.

Due to the low sulphate content (13%) and gentler pH, Bullet Chelated Iron has a low level of antagonism to the soil microflora which breakdown thatch.

Instantly bioavailable, Bullet Chelated Iron provides rapid take-up and outstanding presentational green-up of turf areas.

Chelate Molecule

What is a chelate?

Chelate – pronounced “Key-late” – is derived from the Greek word χηλή, (chēlē) meaning claw because the chelating molecule lies around the central molecule like the claws of a lobster. Practically, a chelating agent is an organic molecule which in simple terms encapsulates a plant nutrition molecule, protecting it from precipitation which would make the nutrient unavailable. Ions encapsulated within a chelating agent are far more likely to be absorbed into the plant via the roots and leaf tissue due to changes to the chelated molecules surface properties. It is this which results in greater efficiency of the applied nutrient.
