Hortipray® MKP is a soluble monopotassium phosphate fertiliser in the form of a free flowing crystalline powder.

Benefits

Hortipray® MKP quickly dissolves to provide the much needed phosphorous and potassium to plants at all growth stages, in hydroponics as well as soil grown crops. Our product is free of chlorine, sodium and heavy metals.
Hortipray® MKP has been produced for 20 years by Prayon at our plant in Puurs, Belgium. The high quality of our standard product makes Hortipray® MKP suitable for all fertigation systems through drip irrigation, NFT, sprinklers, centre pivots and lateral movement irrigation systems

Recommendations

Hortipray® MKP can be mixed with all water-soluble fertilisers, except for calcium fertilisers and concentrated magnesium solutions. In hydroponic systems, it should normally be added to the B tank along with the sulphates and trace elements.
Hortipray® MKP has a buffering effect which will help stabilise the pH of the solution at around 4.5.
