Description
Monopotassium phosphate, MKP, (also potassium dihydrogen phosphate, KDP, or monobasic potassium phosphate), KH2PO4, is a soluble salt of potassium and the dihydrogen phosphate ion which is used as a fertilizer, a food additive, and a fungicide. It is a source of phosphorus and potassium. It is also a buffering agent. When used in fertilizer mixtures with urea and ammonium phosphates, it minimizes the escape of ammonia by keeping the pH at a relatively low level.
Applications of Monopotassium phosphate:
1. Agriculture & Fertilizer Industry
- Premium Phosphorus & Potassium Source: Used in fertilizers to promote root development and flowering.
- Hydroponics & Greenhouse Cultivation: Provides balanced nutrition in controlled environments.
- Foliar Fertilizer: Enhances nutrient uptake and crop yield.
- Drip Irrigation & Soil Application: Improves nutrient absorption and soil health.
2. Food & Beverage Industry
- Food-Grade Additive: Used as a buffering agent and pH regulator.
- Beverage & Dairy Processing: Maintains stability in food formulations.
- Preservative & Emulsifier: Enhances texture and shelf-life of processed foods.
3. Pharmaceutical & Medical Applications
- Nutritional Supplements: Provides essential phosphate and potassium for metabolic processes.
- Electrolyte Replenishment: Used in medical formulations and IV fluids.
- Laboratory Reagent: Utilized in pharmaceutical testing and research.
4. Industrial & Chemical Applications
- Buffering Agent: Maintains pH stability in chemical formulations.
- Water Treatment & Purification: Used in phosphate-based treatments.
- Detergents & Cleaning Products: Enhances stability in cleaning formulations.
Storage
