Iron sulphate gives the initial colour, iron sucrate gives a gentle and consistent release making iron available to the plant over several months to ensure turf remains a brilliant green.
A supremely formulated specialist fertiliser that can be used all year round. The formulation has 65% of the iron derived from iron sucrate, so performance and longevity can last up to 3 months. Improves the appearance of greens, golf tees and approaches, high value lawns and sports pitches.
Duragreen is low in both nitrogen and sulphur but contains high potassium and an additional 9.9% calcium to harden the turf. Duragreen is ideal for application to turf areas as a treatment before the onset of winter, or as an early season starter. Will stimulate plant colour and improve hardiness without stimulating excessive growth.

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.
