Chemical Name: Mono potassium phosphate

Chemical Formula: KH2PO4

Molecular Weight: 136.09

CAS No.: 7778-77-0

Properties

MKP is a soluble salt 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 escape of ammonia by keeping the pH at a relatively low level. It

is often used as a nutrient source in the greenhouse trade and in hydroponics.

Composition

Benefits

• Fully water-soluble

• Consists of 100% plant nutrient
•  
• Free of chloride, sodium and other detrimental elements for plants
•  
• Safe for plants and humans: has a moderately low pH and low salt index
•  
• Suitable for the fertigation, foliar application and production of fertilizer blends and nutrient Solutions

Applications

Fertigation

It is recommended to use MKP as a source of phosphorus and potassium where nitrogen levels

should be kept low. Because of its unique characteristics, MKP can be applied through any irrigation

system and on any growth medium. Unlike phosphoric acid, MKP is moderately acidic. Therefore, it

is not corrosive to fertilizer pumps or to irrigation equipment.

Compatibility

MKP is compatible with most water-soluble fertilizers, except for fertilizers containing calcium (Ca++)

or magnesium (Mg++). To apply MKP in combination with calcium or magnesium fertilizers, use two

fertilizer tanks. If only a single fertilizer tank is available, apply those fertilizers at different times.

Field-crops and vegetables: On young leaves, spray 14.3kg/Ha. MKP is recommended in most

crops. On mature leaves and more tolerant crops, spray 21.4 kg/Ha. May be applied.
