Potassium Nitrate – Water Soluble Potassium Source

Potassium Nitrate (KNO3) – Water Soluble Potassium Source

Potassium nitrate provides an ideal 13-0-46 N:K ratio, delivering potassium in its most soluble form. It is the highest-solubility potassium fertilizer available — suitable for all crops, growing media, and fertigation systems.

Key Features

• Highest solubility of all potassium-based fertilizers
• Potassium in immediately plant-available form
• Nitrate-N does not compete with calcium for root absorption in hydroponics
• Compatible with calcium-rich waters — no risk of precipitation
• Chloride-free — ideal for salinity-sensitive crops
• Suitable for all soil types, growing media, and production systems

Ideal Applications

• Hydroponic nutrient solutions
• Fertigation: drip, micro-jet, center pivot, sprinklers
• Foliar spray programs
• High-K demand crops at productive and ripening stages
