What it is / When to use

Chloride-free nitrate-potassium source for fruiting and quality

Potassium Nitrate is a fully water-soluble crystalline fertilizer raw material, KNO3, CAS 7757-79-1, NOP 13.5-0-46, supplying typically K2O 46% with N 13.5% in fast-acting nitrate form and very low chloride (Cl ≤0.2%). RunziChem exports it as a chloride-free potassium-nitrogen source for fertigation and foliar programs.

  • What it is Potassium nitrate (nitrate of potash, NOP), KNO3, CAS 7757-79-1, white water-soluble crystal.
  • When to use Use it at fruiting and quality stages, in drip fertigation and foliar sprays, and wherever a chloride-free nitrate-potassium source is specified.
  • Honesty note specifications are industry-typical values for evaluation; final values are confirmed per batch COA.

Applications

Where Potassium Nitrate fits

Confirm crop, rate, compatibility, and local label requirements before application.

Potassium + nitrate nitrogen

Delivers K2O 46% together with N 13.5% in fast-acting nitrate form in one soluble raw material.

Fruiting and quality stages

A preferred potassium source during fruit sizing and quality building, when nitrate nitrogen supports uptake.

Chloride-free source

Chloride Cl ≤0.2% makes it suitable for chloride-sensitive crops and salinity-managed programs.

Fertigation & foliar

Fully water-soluble crystal for drip fertigation, foliar spraying, and soluble blend production.

Compare with SOP / CAN

For potassium plus sulphur compare Potassium Sulphate (SOP); for a calcium-nitrate program compare Calcium Ammonium Nitrate (CAN).

Batch documents

TDS, COA, and SDS support procurement and formulation review.

Buyer FAQ

Potassium Nitrate questions

When should I choose potassium nitrate instead of potassium sulphate?
Potassium nitrate (KNO3, NOP 13.5-0-46) supplies K2O 46% together with N 13.5% in fast-acting nitrate form and carries almost no chloride (Cl ≤0.2%), so it suits fruiting and quality stages where nitrate nitrogen is wanted. Choose potassium sulphate (SOP) instead when you need potassium plus sulphur (S 17-18%) and no extra nitrogen. Both are low-chloride sources for chloride-sensitive crops.
Is RunziChem potassium nitrate fully water-soluble for fertigation and foliar use?
Yes. Potassium nitrate is supplied as a fully water-soluble crystalline or prilled grade for drip fertigation, foliar spraying, and soluble blend production. With N 13.5% nitrate, K2O 46%, and Cl ≤0.2% it dissolves cleanly for injection. Exact solubility grade and particle form are confirmed per inquiry and per batch COA.
What are the typical specifications and CAS number of potassium nitrate?
RunziChem potassium nitrate is KNO3, CAS 7757-79-1, with industry-typical N 13.5% (nitrate), K2O 46%, and chloride Cl ≤0.2%, supplied as a white water-soluble crystal or prill. These are industry-typical values for buyer screening; the exact grade and analysis are confirmed per inquiry and per batch COA.
Are the nitrogen and potassium values guaranteed?
No. The figures shown for potassium nitrate, such as N 13.5%, K2O 46%, and Cl ≤0.2%, are industry-typical values for buyer screening. The current batch certificate of analysis (COA) confirms the final nitrogen content, potassium content, chloride, moisture, and appearance for the lot you receive.
