Monopotassium Phosphate (MKP) 0-52-34 25 Kg

Monopotassium Phosphate (MKP) is a fully water-soluble mono-potassium phosphate fertilizer, a highly efficient source of phosphorus and potassium for plants.

As a nitrogen-free fertilizer, Monopotassium Phosphate (MKP) is the preferred source of phosphorus and potassium, when nitrogen fertilization should be limited. A common case is at early growing season, when phosphorus and potassium are needed at high rates for the establishment of root system. Application of MKP, at the productive stages of sugar-rich fruit crops helps to increase sugar content and to improve the quality of these.

Monopotassium Phosphate (MKP) can be applied in combination with other fertilizers, to meet crop nutritional needs throughout the growth cycle. Its high purity and water-solubility make MKP an ideal fertilizer for fertigation and for foliar application. Additionally, Monopotassium Phosphate (MKP) is suitable for preparation of fertilizer blends and production of liquid fertilizers. When applied as foliar spray, Monopotassium Phosphate (MKP) acts as a suppressor of powdery mildew.

The advantages of Monopotassium Phosphate (MKP):

Fully water-soluble
Consists of 100% plant nutrients
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

Monopotassium phosphate for plants

Monopotassium phosphate (MKP) is a widely used phosphorus and potassium fertiliser for plants, it results in optimal flower production, root growth and nutrient uptake of plants.

The high level of Phosphate in our Monopotassium Phosphate (MKP) increases cell division and development of new plant tissue. The presence of Potassium plays an important role in protecting the plant from early stress, as well as providing a good support for the fruits in early fruit set.

Water solubility

The solubility of Haifa MKP is enhanced by increase in water temperature, as shown in the following table.

Water temperature (ºC) 0 10 20 30 40
Solubility (g/100g water) 14.8 18.3 22.6 28.0 33.5

pH and EC

Haifa MKP has a moderately low pH that remains almost constant at different concentrations.

Concentration (%) 0.1 0.2 0.3 1.0 5.0
PH 4.7 4.6 4.6 4.4 4.2

The electrical conductivity (EC) increases substantially when high concentrations of Haifa MKP are used, and yet, its low salt index assures safe use.

Concentration (%) 0.1 0.2 0.3 1.0 5.0
EC (mS/cm) 0.86 1.66 2.5 7.4 27.8

Monopotassium Phosphate Foliar Spray

Foliar application of Monopotassium Phosphate is an optional supplement to soil fertilization at growth stages when high levels of phosphorus and potassium are required. At early season foliar application with Monopotassium Phosphate promotes the establishment of healthy root system.

Monopotassium Phosphate is an efficient suppressor of powdery mildew in susceptible crops (deciduous, vineyards, mango, cucumbers, melons, roses and others). Application of 1% Monopotassium Phosphate mixed with systemic fungicides improves the efficiency and enable to reduce application rates of the latter.

On young leaves, spray concentration of 1.0% Monopotassium Phosphate is recommended in most crops. On mature leaves and more tolerant crops, concentration of 2.0% may be applied
