Potassium + Nitrogen
Potassium Nitrate
Kaliumnitrat · KNO₃ · NOP · 13-0-46
13% N · 46% K₂O
Potassium Nitrate (KNO₃) is a fully water-soluble, chloride-free fertilizer supplying both nitrate nitrogen and potassium. Its high solubility and clean dissolution make it the reference product for fertigation, drip irrigation and greenhouse crops, while the absence of chloride protects quality-sensitive crops such as potatoes, fruit, vines, berries and vegetables. Cerantis sources potassium nitrate in soluble crystalline and prilled grades for European distributors and growers.

Frequently Asked Questions
What is potassium nitrate used for?
Potassium nitrate supplies readily available nitrate nitrogen and potassium without any chloride. It is mainly used in fertigation, greenhouse cultivation and foliar feeding of high-value crops such as fruit, vines, vegetables and potatoes, especially during fruit development.
Is potassium nitrate chloride-free?
Yes. Unlike MOP (potassium chloride), potassium nitrate contains no chloride, which makes it suitable for chloride-sensitive crops where chloride would reduce starch content, quality or storability — for example potatoes, grapes and berries.
Potassium nitrate vs. MOP — what is the difference?
MOP (potassium chloride, 60% K₂O) is the cheapest potash source but contains chloride and is not water-soluble in fertigation grade. Potassium nitrate is fully soluble, chloride-free and also supplies nitrate nitrogen, but at a premium price. Use MOP for broad-acre base dressing and KNO₃ for fertigation and quality crops.
How is potassium nitrate applied as a foliar or fertigation feed?
For fertigation it is dissolved directly in the irrigation water; for foliar feeding a 0.5–1% solution is typical. Thanks to its high solubility it leaves no residue and will not clog drip emitters. Contact us for crop-specific dosing guidance.
Can potassium nitrate be used in organic farming?
Mined/technical potassium nitrate is generally not permitted in EU organic production, while some naturally derived grades may be. Always verify the specific grade against EU Regulation 2018/848 and your certifier before use.
