ICL’s PKpluS stands out as a superior fertilizer due to its comprehensive nutrient profile and advanced formulation. It delivers five essential nutrients—phosphorus, potassium, sulfur, magnesium, and calcium—in a single application, ensuring balanced nutrition for crops. The inclusion of Polysulphate® (polyhalite) allows for the gradual release of nutrients, reducing leaching risks and enhancing nutrient availability throughout the growing season. This extended release supports optimal crop growth and quality, particularly in soils with low potassium levels. Additionally, ICL PKpluS’s premium granules ensure even distribution and efficient nutrient uptake, contributing to higher yields and improved crop resilience.
A considerable proportion of the potassium content is in sulfate form, allowing flexible use in many crops, and also reducing the chloride input.
ICL PKpluS offers flexibility in nitrogen management. By separating nitrogen applications, you can apply nitrogen at the optimal time for your crop, in the ideal form, and under the best weather conditions, reducing the risk of over-application, leaching, and waste. With ICL PKpluS, you can enhance nitrogen use efficiency, maximizing crop performance while minimizing unnecessary costs and environmental impact.
