Description
ICL Greenmaster Spring & Summer 12-4-6 (14-5-7 %w/v) Liquid Advance Fertiliser
Engineered for professional turf managers who demand consistency, this advanced liquid fertiliser keeps surfaces performing at their peak through changing and challenging growing conditions. It replenishes nutrients removed through regular mowing, helping maintain strong colour, sward density and rapid recovery across high-wear areas.
At its core is MTU®, a patented biostimulant designed to optimise energy production and improve nitrogen efficiency — particularly during periods of environmental and play stress. The inclusion of pidolic acid further enhances nutrient uptake and supports plant resilience, ensuring applied inputs are used to their full potential.
A comprehensive trace element package completes the formulation, promoting rich, consistent colour, improved recovery and robust plant health — delivering reliable, professional-grade results for fine turf surfaces.
ICL liquid products - Greenmaster Liquids, H2Pro and Greenmaster Blade, are fully compatible with one another so that the optimal product performance is always assured. Please note that Ca Booster is not tank-mixable.
The formulation incorporates cutting edge technologies to maximise turf performance and to provide the best value for money. The key component within the formulation is TMax, the very latest development from ICL R&D to maximise the efficiency of nutrient delivery to turf.
Nutrients are often locked-up in the soil. Greenmaster Liquids with TMax unlocks these previously unavailable nutrients. The result is a better nutrient balance in the soil and improved turf quality.
