Microfertilizer ORAKUL® colofermine of calcium

ORAKUL® colofermine of calcium is intended for feeding vegetables, cucurbit crops and perennial plantings. It is used for elimination of plant physiological disorders due to calcium deficiency.

When calcium deficiency takes place, under fruit skin its flesh becomes brown in some places. Then in these places on the skin appear spots (subcortical spotting), which cork over time (cork spot). The fruits lose their marketable qualities.

ORAKUL® colofermine of calcium contains water softener. Therefore, the use of any dressers in hard water (high content of Ca2+ and Mg2+ salts) together with ORAKUL® colofermine of calcium does not reduce their effectiveness. Hardness salts are securely bound by the formulation component without causing turbidity. Any danger of the calcium sulphate (gypsum) formation, which can lead to breakdown of spraying machinery, is eliminated. Applications shall be conducted by the solution, which was prepared just before application.
ORAKUL® colofermine of calcium has a significant physiological effect on plants, namely:
  • regulates the construction of the cell membranes;
  • provides resistance to pests;
  • increases the viscosity and permeability of protoplasm;
  • stimulates processes of nitrogen fixation and transition of carbohydrates
  • improves fruit marketable qualities.
It is recommended for use in conjunction with VIMPEL® plant growth stimulator .
