Hortipray® Potassium Nitrate (NOP 13.7-0-46.3) has been designed as a fully water-soluble crystalline potassium nitrate fertilizer.

Hortipray® Potassium Nitrate NOP is a high quality potassium nitrate source providing nitrogen and potassium to plants at all growth stages, in hydroponics as well as soil grown crops.

Our products are free of chlorine, sodium and heavy metals. In the form of a free flowing, fine crystalline powder, it dissolves quickly in water and can be used in all fertigation systems, such as drip irrigation, NFT, sprinklers, centre pivots and lateral movement irrigation systems.

Hortipray® NOP has a low pH (4-5) which helps the product dissolve in water and keeps other ingredients available for absorption by the plants.
