'Through extensive testing, we have validated globally that, through the K rate response curve, using less K in POLY4 straight applications and in blends delivers better results. Crop fertilizer plans will be delivering not just potassium (K2O) but also other macro nutrients such as magnesium and sulphur. Therefore, it is not an equitable comparison to compare MOP and POLY4. Under these circumstances there is little difference between the weight of fertilizer required for either plan.'
