watersoluble fertilizer Phosphate Fertilizer, MKP 0-52-34,
Monopotassium Phosphate
Proportional Nutrition
The phosphorus and potassium concentration in the irrigation water depends on the quantity of Mono Potassium Phosphate (MKP 0-52-34) in the tank mix, and on the injection ratio. Use the following table to calculate the quantity of Mono Potassium Phosphate (MKP 0-52-34) and the injection ratio needed to reach your target concentration in the irrigation water.

Foliar Feeding
Foliar application of Mono Potassium Phosphate (MKP 0-52-34) 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 Mono Potassium Phosphate (MKP 0-52-34) promotes the establishment of healthy root system. Mono Potassium Phosphate (MKP 0-52-34) is an efficient suppressor of powdery mildew in susceptible crops (deciduous, vineyards, mango, cucumbers, melons, roses and others). Application of 1% Mono Potassium Phosphate (MKP 0-52-34) mixed with systemic
fungicides improves the efficiency and enable to reduce application rates of the latter. Mono Potassium Phosphate (MKP 0-52-34) is compatible with most commonly used pesticides and fertilizers. However, it should not be mixed with calcium or magnesium fertilizers. Also, iron, manganese, zinc and copper must be in chelate form.
Field-crops and vegetables: On young leaves, spray concentration of 1.0% Mono Potassium Phosphate (MKP 0-52-34) is recommended in most crops. On mature leaves and more tolerant crops, concentration of 2.0% may be applied.

It is advisable to confirm compatibility of your intended spray-mix by preparing a sample of the spray materials at their recommended concentrations in order to rule out the possibility of a detrimental cross reaction. This mixture should be sprayed onto small area prior to commercial treatment, in order to assess whether an adverse effect occurs.
Note: Above application recommendations are under general conditions, your consultation to local agronomists are strong recommended.
