Monopotassium Phosphate (MKP)
Monopotassium phosphate is the most highly concentrated in phosphorus soluble PK fertilizer. It is used both in protected and open field for any phenological stages of plant development, also for foliar application. Monopotassium phosphate is 100% soluble in water, quickly absorbed by plants, which allows to use it for root application through irrigation systems. It is especially recommended to use in hydroponics, as it does not contain chlorine and any insolubles.
Do not mix with calcium- and magnesium-containing products.
