Ultrasol® SOP WS is a source of Potassium (K) that is completely water-soluble. Its high concentration of Potassium, but absence of Nitrogen (N) and Phosphorus (P), allow it to supply the required amount of Potassium (K), mainly in the final phase of the fruit growth cycle, in general.
In alkaline soil conditions, the acid pH helps to reduce the pH of the rhizophore, thereby improving the availability of phosphate and certain microelements.
