Stronger crops for tougher seasons

POLY4 helps your crops stay strong through drought, disease, and physiological stress. It reinforces plant cell walls, supports healthy root growth, and builds resilience from the inside out —helping you protect yields and avoid costly losses.

Stronger cells. Smarter defence. Reliable calcium for resilient growth

Calcium doesn’t just build tougher tissue - it activates your crop’s immune system. From sealing weak spots to signalling pathogen attacks, it’s your first line of biological armour.

Balanced nutrition. Built-in resilience.

When crops get the right mix of calcium, magnesium, and potassium, they grow stronger from the inside out - resisting cracking, collapse, and infection. POLY4 delivers full-spectrum nutrition to keep your crop firm, healthy, and stress-tolerant.

Dry spells don’t have to mean weak crops.

With balanced nutrition, plants use water more efficiently, build stronger roots, and stay productive - even under drought stress. It’s how POLY4 protects yield when the rain doesn’t come.
