The benefits of POLY4

POLY4 is a natural, multi-nutrient fertiliser helping farmers grow more sustainably, profitably and resiliently - season after season.

POLY4 is a high-performing fertiliser that supports sustainable farming at scale.

It delivers four essential nutrients – potassium, sulphur, magnesium and calcium – in a single source.

POLY4 ensures that each harvest builds a stronger foundation for the next, enhancing multiple efficiencies at once to create value beyond the sum of its parts.

We break down the multitude of POLY4 benefits into five categories:

Enhances output

POLY4 helps you grow better crops, bigger harvests, and stronger profits year after year.

Unlocks access to nutrients to maximise their use

Unique properties of POLY4 improve nutrient availability in the soil and enhance nutrient use efficiency - reducing waste in the field and saving you money.

Strengthens resilience

POLY4 helps crops stand strong against disease, stress and tough weather - securing your yields in uncertain times.

Cares for your soil

POLY4 enriches your soil helping to improve its structure and function without negatively impacting its long-term health.

A perfect fit for sustainable farming

POLY4 helps you farm smarter, in a nature-friendly way - so you can keep farming for years to come.

POLY4 helps safeguard every season, allowing farmers to focus on what truly matters – their land and their livelihoods.

"POLY4 is much more than a bog-standard fertiliser."
