Our Technical Sales Manager for Iberia Carlos Bayón Puertas has been part of a very topical debate about how the fertiliser market is responding to today’s geopolitical challenges and why solutions like POLY4.com matter more than ever.
We don’t need to invest more, we need to invest smarter!

POLY4 delivers a steady supply of potassium (K), magnesium (Mg), sulfur (S) and calcium (Ca) throughout the growing cycle. The natural behaviour of the mineral, which is optimised through the engineered granule gives crops more time to absorb nutrients, supporting yield and quality.
Unlike conventional fertilisers that often release nutrients all at once, POLY4 feeds crops gradually and efficiently - reducing losses and supporting healthier growth.

Don’t risk wasting inputs you’ve already paid for.
Nutrient losses, uneven uptake and soil deficiencies quietly chip away at profits long before harvest. POLY4 helps reduce that risk by delivering four essential nutrients to crops when they need them, while also helping unlock nutrients already present in the soil.
By maximising nutrient availability and efficiency, POLY4 ensures more of every application works harder for your farm - protecting your time, your inputs and your investment. 🌱🚜

Every season has enough challenges - nutrition shouldn’t be one of them.
Unbalanced inputs can mean weaker crops, lower efficiency and lost yield. POLY4 helps reduce that risk by supplying multi‑nutrient support in one application.
Grow more, grow healthier, waste less with POLY4.
