A seamless integration

POLY4 blends with almost all other inputs

To limit waste and improve efficiency, farmers often apply several fertilisers at once in the form of dry blends, reducing the number of field passes, saving valuable time, and cutting fuel costs. It’s therefore essential that the ingredients are compatible and do not cause undesirable reactions that could affect the usability of the blend.

Conclusions from advanced testing conducted by the International Fertilizer Development Center (IFDC) show that POLY4 is compatible with almost all other fertiliser inputs.

POLY4's compatibility:

Independent testing conducted by International Fertilizer Development Center (IFDC) showed that POLY4 is:

  • A compatible input for blending into NPK fertilisers.

  • Fully compatible with common P, K and Mg fertilisers and urea.

  • Comparable to MOP in blends with AN and CAN.
