Recommendations
Hortipray
®
MAP 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
®
MAP has a buffering effect which will help stabilize the pH
of the solution at around 4.2.
Please ask your local distributor or agronomist for more advice.
