Monopotassium phosphate aka MKP fertiliser (KH2PO4), is a soluble salt of potassium and the dihydrogen phosphate ion which is generally used as a fertilizer, a food additive and a fungicide.
It contains both phosphorus (P) and potassium (K). When used in fertiliser mixtures with urea and ammonium phosphates, it minimizes escape of ammonia by keeping the acidity at a relatively low level.
The product is a fully water soluble form of phosphorus and potassium fertiliser making it particularly suited to a wide range of horticultural crops. It comes as a free flowing, fine crystalline powder which dissolves quickly when mixed in water.
MKP fertilisers are suited to applications through fertigation systems – hydroponics, drip systems, low throw sprinklers, centre pivots, spray units and misters.
