Description

Application Recommendations

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, it can be applied through any irrigation system and on any growth medium. 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 the system includes only one tank, apply the fertilizers at different times.

Foliar Nutrition

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

MKP is an efficient suppressor of powdery mildew in susceptible crops (deciduous, vineyards, mango, cucumbers, melons, roses and others). Application of 1% MKP mixed with systemic fungicides improves the fungicide efficiency and allows it to be used at reduced application rates.

MKP is compatible with most commonly used pesticides and fertilizers. However, it should not be mixed with calcium or magnesium fertilizers. Iron, manganese, zinc and copper must be in the form of chelates.

Field-crops and vegetables: On young leaves, spray concentration of 1.0% MKP is recommended in most crops. On mature leaves and more tolerant crops, concentration of 2.0% may be applied.
