Crystalline agricultural potassium nitrate that stays free-flowing and dissolves readily
Fertigation systems depend on a fertilizer that dissolves quickly and cleanly. Our crystalline potassium nitrate (KNO₃) is made for exactly that job. It supplies nitrate nitrogen and potassium, goes into solution fast, and helps keep drippers, sprinklers and filters running while delivering nutrients evenly to the root zone.
Why choose our crystalline potassium nitrate?
Truly 100% water-soluble
- Fast dissolving: fine, uniform white crystals that go into water quickly and leave a clear solution with very little residue.
- Dependable in irrigation lines: low insoluble matter helps reduce the risk of blocked drip emitters, sprinklers and filters, so the system keeps running smoothly.
- Even nutrient delivery: the crystals dissolve thoroughly, so the solution has a consistent concentration and every litre carries the same nutrient load.
Innovative organic anti-caking technology
- Stays loose: a food-grade organic anti-caking agent forms a thin protective film on the crystals, blocking moisture and helping to prevent caking at the source.
- Long shelf life: the crystals stay loose and free-flowing even after long storage in humid conditions, so a bag can be used straight away without breaking up lumps.
- Soil and crop friendly: the organic additive is formulated to be gentle on soil and crops.
