Applications
Agriculture and Horticulture
- Fertilizer: Enhances phosphorus and potassium levels in soils deficient in these nutrients, ideal for crops like tomatoes, potatoes, and grapes.
- Hydroponics: Provides balanced nutrition in soilless systems, preventing nutrient lockout.
- Foliar Feeding: Quick absorption through leaves for mid-season boosts.
Food and Beverage Industry
- Acts as a buffering agent and sequestrant in soft drinks, dairy products, and baked goods to stabilize pH and improve texture.
- GRAS (Generally Recognized as Safe) status by FDA for food-grade applications.
Industrial Uses
- Flame retardant in textiles and polymers due to its phosphorus content.
- Component in fire extinguishers and water treatment for corrosion inhibition.

Frequently Asked Questions (FAQs)
What is Monopotassium Phosphate (MKP)?
Monopotassium Phosphate (MKP) is a fertilizer grade compound with the formula KH₂PO₄ and CAS 7778-77-0, supplying phosphorus and potassium to plants. It’s a white, odorless powder that’s highly water-soluble and used to correct nutrient deficiencies.
How do I apply MKP in my garden or farm?
For soil application, dissolve 1-2 kg per hectare in irrigation water. For foliar sprays, use a 0.5-1% solution every 10-14 days during vegetative growth. Always conduct a jar test for compatibility with other inputs.
Is MKP safe for organic farming?
Yes, MKP is approved for organic use under many certifications (e.g., OMRI-listed variants), as it’s derived from natural mineral sources and free from synthetic additives.
What is the shelf life of MKP?
When stored in a cool, dry environment away from moisture, MKP remains stable for 2-3 years without degradation of nutrient content.
Can MKP be used with other fertilizers?
Absolutely—MKP is compatible with most nitrogen sources like urea, but avoid mixing with calcium-based fertilizers to prevent precipitation. It’s excellent in NPK blends.
Does MKP affect soil pH?
MKP has a mildly acidic pH (4.5), but in typical field rates, it has negligible impact on soil pH, making it suitable for neutral to alkaline soils.
What are the packaging options for bulk MKP?
We offer 25kg multi-wall paper bags, 50kg drums, and 1000kg IBC totes, all lined for moisture protection and palletized for safe shipping.
