Potassium Nitrate (KNO₃) is a fully water-soluble, chloride-free fertilizer that provides two essential macronutrients in a readily available form: 13% nitrogen (N) (as nitrate) and 46% potassium oxide (K₂O). Supplied as a crystalline powder, it is ideal for fertigation, foliar applications, and as a raw material in high-purity NPK formulations.

Caracteristiques:

• 100% water-soluble – dissolves quickly, leaves no residue
• 13% N (as NO₃⁻) – nitrate nitrogen for immediate uptake and improved cation absorption
• 46 % K₂O – supports fruit quality, sugar formation, turgor pressure, and stress tolerance
• Chloride-free and sodium-free – safe for sensitive crops and long-term soil structure
• Neutral pH (6–7) – ideal for fertigation in all water types

Agronomic benefits:

• Stimulates flowering, fruit set, and sugar translocation
• Improves fruit size, firmness, taste, and shelf life
• Supports plant resilience against drought, disease, and lodging
• Enhances calcium and magnesium uptake due to nitrate synergy

Recommended applications

• Fertigation in vegetables, fruit trees, flowers, and protected crops
• Foliar spray for rapid potassium and nitrogen delivery
• As a key input in water-soluble NPK blends and hydroponic nutrient formulas

Due to local regulations some markets like Brazil or Mexico are using a NKS version of this product, which has some added Sulphur (S).
