Product Description
An acidic PK fertiliser (0-60-20) - phosphoric acid in solid crystalline form. Dissolving to pH ~2.2, it acidifies fertigation water, dissolves bicarbonate scale and keeps drippers clean while supplying fully available phosphorus and chloride-free potassium. Uniquely for a phosphate, its acidity allows one-tank mixing with calcium and magnesium fertilisers, and it releases locked micronutrients (Fe, Zn, Mn, Cu) in calcareous and alkaline soils. Replaces phosphoric acid, MAP, MKP or UP as the P carrier in hard-water fertigation.
