Greenmaster Liquid Spring&Summer

ICL Greenmaster Spring & Summer 12-4-6 Liquid Fertiliser

ICL Greenmaster Liquid fertilisers are an extremely direct and effective way of giving the grass plant the right nourishment at the right time. Generally speaking they work over a short period, which is why it is often a good idea to combine them with a basic dosage of granular fertilizer.

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.
