Manvert Potassium is a liquid potassium solution containing organic acids which optimize the assimilation thereof. Additionally, Manvert Potassium is specifically formulated to enhance the colour, weight, size and sugar content of fruit.
Most liquid solutions with high potassium content, containing more than 20% K2O, contain hydroxide or potassium carbonate in their formulation, causing the pH of the spray solution to increase to very high values (pH > 12). The application of these high pH products on plants increases the risk of phytotoxicity on the leaves.
In order to avoid this risk, Manvert Potassium is formulated in such a way which decreases the pH of the spray solution to between 6 and 7, creating a natural buffer effect.
