Monopotassium phosphate

From Biocrawler, the free encyclopedia.

Monopotassium phosphate -- KH₂PO₄ -- (MKP) is a soluble salt which is used as a fertilizer, a food additive and a fungicide. It is a source of phosphorus and potassium, and is a buffering agent. When used in fertilizer mixtures with urea and ammonium phosphates, it minimizes escape of ammonia by keeping the pH at a relatively low level.

Fertilizer grade MKP contains 52% P₂O₅ and 34% K₂O, and is labeled 0-52-34. It is often used as a nutrient source in the greenhouse trade and in hydroponics.
