Hakaphos Calcidic

HAKAPHOS CALCIDIK is a water-soluble fertilizer with a balanced content of macro- and microelements in chelated form and calcium for fertigation systems.


  • fertilizers contain calcium, which avoids the necessity for application of calcium nitrate and use of conventional fertilizers;
  • fertilizers have a low pH;
  • balanced content of nitrogen, phosphorus and potassium, in accordance with the phases of plant growth and development;
  • fertilizer contains nitrogen in ammonium and nitrate forms, there is no nitrogen in the amide form, because it is ineffective in fertigation systems;
  • effective providing plant with available magnesium and calcium;
  • 100% solubility regardless of the quality of water;
  • the highest rate of dissolution;
  • high availability of trace elements due to chelation form;
  • chlorine-free.


Fertilizers due to their acidity increase the efficiency of nutrient absorption from the alkaline and calcareous soils, increase the absorption of nutrients from the soil. Synergism processes are enhanced, the amount of chlorophyll is increased, and photosynthesis is improved, which in turn leads to increase of plant productivity.

Increased acidity prevents and eliminates the blocking of droppers by bicarbonates in the tapes (tubes) for drop irrigation.

In the preparation of stock solutions for fertigation Hakaphos Calcidik reduces the pH of the solution in the tank, increases the availability of accessible nutrients, increases the permanence of pesticides (insecticides, fungicides) if they are applied together and mixed in one tank during the fertigation.

Due to its characteristics Hakaphos Calcidik is suitable for almost all calcareous and alkaline Ukrainian soils. It obviates a necessity for strong and dangerous acids (nitric, phosphoric).

Hakaphos Calcidik contains a balanced ratio of nutrients (macro, meso and micro-elements), which fully meets the needs of all crops with drip irrigation (vegetables, fruits and vineyards) in all phenological stages of growth. Very low rate of the ES that makes it possible to use in solutions with high salt concentrations.

Preparation of working solution

  • Prepare solution by dissolving of 15 kg of fertilizers in 100 l of water at a water temperature > t = 18 ° C, or 20 - 25 kg of fertilizer at a water temperature
  • to regulate the dosage for getting a final concentration of the working solution in the range of 0.05 - 0.5%
  • after application to use plain water for 15 - 20 minutes for irrigation system cleaning
