MKP Fertilizer

Monopotassium phosphate (MKP) (also, potassium dihydrogenphosphate, KDP, or monobasic potassium phosphate) is the inorganic compound with the formula KH₂PO₄. Together with dipotassium phosphate (K₂HPO₄^.(H₂O)_x) it is often used as a fertilizer, food additive, and buffering agent. The salt often cocrystallizes with the dipotassium salt as well as with phosphoric acid.^[6]

Single crystals are paraelectric at room temperature. At temperatures below −150 °C (−238 °F), they become ferroelectric.

Benefits

• It is recommended for root development, flowering and fruit set.
• It has a limited caking sensitivity, a buffering effect and a low salt index.
• It also increases nitrogen utilization and frost resistance.
• MKP fertilizer can be applied as a foliar spray or through fertigation.
