Haifa MKP™ Application Recommendations

Haifa MKP™ Application Recommendations

Haifa MKP™ is the preferred source of phosphorus and potassium when nitrogen fertilization should be limited:
  • At the early stages of the growth season when phosphorus and potassium are needed at high rates for the establishment of root system.
  • During the productive stages of sugar-rich fruit crops, to increase sugar content and to improve fruit quality.

Haifa MKP is ideal for application by Nutrigation™ and foliar sprays.


Nutrigation™ (fertigation)

It is recommended to use Haifa MKP™ as a source of phosphorus and potassium where nitrogen levels should be kept low. Featuring moderate acidity, Haifa MKP™ is not corrosive to fertilizer pumps or irrigation equipment.

Compatibility: Haifa MKP™ is compatible with most water-soluble fertilizers, except for fertilizers containing calcium or magnesium. To apply Haifa MKP™ in combination with calcium or magnesium fertilizers, use a two-tank Nutrigation™ system. If the system includes only one tank, apply the fertilizers at different times.

Quantitative Nutrigation™
Each kilogram of Haifa MKP™ in the tank provides 520 grams of P2O5 (230g P) and 340 grams of K2O (280g K).
Proportional Nutrigation™
The phosphorus and potassium concentration in irrigation water depend on the quantity of Haifa MKP™ in the tank mix, and on the injection ratio. Use the following table to calculate the quantity of Haifa MKP™ and the injection ratio needed to reach your target concentration in the irrigation water.

Foliar Nutrition

Foliar application of Haifa 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 Haifa MKP™ promotes the establishment of a healthy root system.

Haifa MKP™ is compatible with most 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, in most crops it is recommended to apply spray concentration of 1%. On mature leaves and more tolerant crops, spray concentration may be increased, up to 2%.

Fruit trees:
Crop Conc. Timing
Citrus 1-3% 2-3 successive monthly sprays at early fruit development, starting 1 month after fruit-set
Stone fruits 1-2% 2-4 applications from fruit-set to fruit coloring
Banana 1-2% 2-6 applications, along with pesticides
Table grapes 1-2% 1 application during fruit-set, 1 during ripening
Wine grapes 2% 1 application during fruit-set, 1 during ripening
1% Every 2 weeks, starting when twigs are 10-14 cm long until veraison, alternated with proper fungicide
Olives 3-5%
  • 1 application in early spring for flower induction and fruit setting
  • 2 applications during fruit development
  • 1 application during sizing and oil filling
It is advisable to assure suitability of 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 on a small area prior to commercial treatment, to assess whether an adverse effect occurs.
