Potassium Nitrate – Water Soluble Nitrogen Source

Potassium Nitrate (KNO3) – Water Soluble Nitrogen Source

Potassium nitrate delivers nitrogen exclusively in nitrate form — the most readily plant-available N source. Unlike ammonium-based fertilizers, nitrate-N does not compete with calcium for root absorption, making KNO3 the preferred nitrogen source in hydroponic and high-calcium fertigation programs.

Key Features

• Nitrogen in nitrate form — immediately available for plant uptake
• Nitrate-N does not compete with calcium at the root zone
• Synergistic NO3⁻ and K₂O uptake — enhances absorption of both elements
• 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
• Crops sensitive to ammonium toxicity or salinity
