Main Applications
MKP has diverse applications across agriculture, industry, and food sectors due to its high purity and solubility.
A. Agriculture (Agricultural Usage)
Foliar Fertilizer: Applied directly to leaves to correct phosphorus and potassium deficiencies rapidly. It improves photosynthesis and nutrient absorption.
Fruit Quality Improvement: During the fruiting stage, it promotes fruit swelling, enhances coloration, and increases sugar content (Brix), making fruits sweeter and more marketable.
Stress Resistance: It strengthens crops against adverse conditions such as drought, frost, lodging, and certain fungal diseases.
Flower and Seed Production: Promotes robust root development, flower bud differentiation, and increases seed setting rate.
Hydroponics & Soilless Culture: Ideal for nutrient solutions due to its high solubility and lack of impurities.
B. Industry (Industrial Usage)
Water Treatment: Used as a high-efficiency buffering agent and phosphorus source in industrial circulating water treatment.
Flame Retardant: Utilized in the production of fire retardants for wood, paper, and fabrics.
Electronics: Used in the manufacturing of piezoelectric crystals and electroplating processes.
Catalyst: Serves as a catalyst or catalyst carrier in organic chemical synthesis.
C. Food Industry (Food Usage)
Food Additive: As a buffering agent, chelating agent, yeast food, emulsifying salt, and nutritional supplement in food processing.
Baking: Used in baking powders to help dough rise.
Packaging & Storage
Packaging: 25kg/bag (PP/PE bags), 1000kg/bag (Jumbo bags), or as per customer request.
Storage: Store in a cool, dry, and well-ventilated place. Avoid moisture and rain during transportation and storage.
