Product Features & Benefits
Potassium nitrate offers a distinctive combination of characteristics that make it valuable for specific agricultural applications, particularly in intensive, high-value crop production.
Key characteristics
Chloride-free potassium
Contains no chloride, making it suitable for chloride-sensitive crops and saline conditions.
Dual nutrient supply
Provides both potassium and nitrogen in a single product, simplifying fertigation programmes.
Fully water-soluble
Dissolves completely without residue, suitable for drip irrigation and foliar applications.
Nitrate nitrogen
Nitrogen is immediately plant-available in the nitrate form for efficient uptake.
Lower salt index
Moderate effect on soil solution salinity compared to some other potassium sources.
Versatile application
Can be used for fertigation, foliar sprays, soil application, and hydroponic systems.
Nutrient composition
Agricultural-grade potassium nitrate typically contains approximately 13% nitrogen (entirely as nitrate, NO₃⁻) and 46% potassium expressed as K₂O (equivalent to about 38% elemental potassium). This composition makes it useful both as a potassium source with accompanying nitrogen and as a nitrogen source with accompanying potassium.
| Nutrient | Content | Form |
|---|---|---|
| Nitrogen (N) | ~13% | 100% nitrate (NO₃⁻) |
| Potassium (K₂O) | ~46% | Water-soluble |
| Chloride | Nil | — |
