Liquid Fertiliser

Liquid nutrients can provide the fastest plant responses with nutrients either taken up directly from the leaf with foliar application or by quickly penetrating the rootzone.

Whether applied by sprayer or fertigation, they are important for sports turf, lawn care, agriculture, horticulture, and hydroponics. Greenbest even supplies liquid fertilisers for use in reed bed filtration, biodigesters and green-walls.  

Our formulations are carefully designed to maximise the performance of the fertiliser in any specific application and can be manufactured and supplied in any quantity, in bulk or retail packs to your specific formulation.

Slow Release Fertiliser 

Liquid fertilisers usually provide a rapid but short lived effect, by using a controlled release nitrogen source the effect can be prolonged.


NMAXX stabilised nitrogen slow release liquid fertiliser manufacturer


NMAXX liquid is a stabilised nitrogen fertiliser that contains urease inhibitors that help prevent the naturally occuring urease from breaking down nitrogen, and nitrification inhibitors that slow the conversion of ammonium to nitrate.

As a result nitrogen remains in the positively charged ammonium form longer, bonding with the soil, and readily available for plant uptake.

NMAXX provides protection against all three forms of nitrogen (N) loss - leaching, denitrification and volatilisation.

NMAXX can provide up to 5 weeks of plant response.

NMAXX is available in a range of standard formulations, as a straight liquid, or can be added to bespoke products.
