General

What is Potassium dihydrogen Phosphate? Also known as KDP, Monopotassium phosphate (MKP), or monobasic potassium phosphate, chemical formula KH₂PO₄, is a soluble salt of potassium and the dihydrogen phosphate ion which is used as a fertiliser, a food additive and a fungicide. It is a source of phosphorus and potassium. It is also a buffering agent. When used in fertiliser mixtures with urea and ammonium phosphates, it minimises escape of ammonia by keeping the pH at a relatively low level.

Consistent Quality: We provide only high-quality Potassium dihydrogen Phosphate, ensuring reliable and consistent performance for all applications.

Shipped from Manchester, UK Facility: Sourced and packaged in non-toxic, chemical-resistant containers to ensure safe handling and preserve product quality during transport.
