Fertilizer 0-0-50 +45SO3 (SOP) is a granular potassium sulfate fertilizer. It is a rich source of potassium, ideal for potassium-demanding crops sensitive to chlorine. Its ideal composition makes it suitable for potassium-demanding crops such as trees, vegetables and legumes.

Potassium is involved in carbohydrate metabolism. It contributes to the increase in the production and quality of the fruit, the oil content of the fruit and the improvement of its organoleptic characteristics. It enhances plant resistance to disease and resistance to abiotic stress (such as high temperature).
