📌 Detailed Introduction of MKP (KH₂PO₄) Fertilizer
✔ What is Mono Potassium Phosphate (MKP)?
Mono Potassium Phosphate (MKP, KH₂PO₄) is a highly water-soluble, chloride-free fertilizer providing essential phosphorus (P₂O₅) and potassium (K₂O) to plants. It is widely used in fertigation, foliar sprays, and hydroponic systems to support root development, flowering, and fruit growth.
✔ CAS Number & Chemical Formula:
CAS Number: 7778-77-0
Chemical Formula: KH₂PO₄
📌 Applications of MKP Fertilizer
✔ Agriculture & Horticulture
Highly efficient source of P₂O₅ (52%) and K₂O (34%) for balanced plant nutrition.
Enhances root development, flowering, and fruit formation.
Improves stress tolerance to drought, diseases, and temperature extremes.
Suitable for soil application, foliar spray, and fertigation.
✔ Hydroponics & Drip Irrigation
100% water-soluble with no clogging in irrigation systems.
Ideal for nutrient solutions in soilless cultivation.
Provides fast nutrient uptake with no soil residue.
✔ Foliar Feeding
Quickly corrects phosphorus and potassium deficiencies in plants.
Enhances chlorophyll production, leading to stronger plant growth.
Prevents leaf chlorosis and weak stems in high-yield crops.
✔ Industrial Uses
Used as a pH buffer in food and pharmaceutical applications.
Found in detergents and water treatment solutions.
📌 Production Method & Raw Materials
✔ Raw Materials Used:
Phosphoric Acid (H₃PO₄)
Potassium Hydroxide (KOH) or Potassium Carbonate (K₂CO₃)
✔ Production Process:
Neutralization – Phosphoric acid is reacted with potassium hydroxide or potassium carbonate.
Crystallization – The solution is cooled and crystallized to obtain pure KH₂PO₄.
Drying & Screening – The crystals are dried and screened to the desired granule size.
Quality Testing & Packaging – Ensuring high purity before shipment.
