Improving microbial mobilisation of key nutrients

Powering soil biology with POLY4

The soil microbiome isn’t just background noise - it’s the engine room of plant nutrition. These tiny organisms drive key processes like mineralisation, nitrogen transformation, and organic matter breakdown.

Mineralisation unlocks nutrients from organic matter, turning them into forms plants can actually use. Nitrogen transformation (like nitrification) makes nitrogen available in the right form, at the right time. Organic matter decomposition keeps nutrients cycling and soil structure improving.

In short, a healthy microbiome keeps nutrients moving - and your plants growing.

How does POLY4 help?

POLY4 supports availability of potassium and calcium - not just through its nutrient content, but by stimulating microbial mobilisation. That means your crops can access larger amounts of these key nutrients when they need it.
