Using Polysulphate to improve NPK Production | ICL

Incorporating Polysulphate into NPK fertilizers adds four fully available nutrients: sulfur, potassium, magnesium, and calcium to the nutrient mix.
When enhanced with Polysulphate, NPK fertilizers have a better hardness to make them easier to handle and apply, they supply more nutrients, improve root development, and above all, deliver better crop quality and higher yields.
