Micronutrient fertilizer LURS® colofermin calcium

LURS® colofermin calcium is a concentrated micronutrient fertilizer for elimination of plant physiological disorders due to calcium deficiency.

*Colofermine is a multicomponent complexing agent (analogue of chelating agents), which consists of various organic compounds, optimally balanced for maximum absorption and plant uptake (up to 100%) of the corresponding nutrients (main active ingredient) in micronutrient fertilizers.

Depending on the type of micronutrient fertilizers, among other components, colofermin may contain colamine, various complexes of amino acids, micronutrients, including nitrogen, sulfur, sodium in sufficiently high concentrations (up to 280 g/L). Therefore, colofermin also serves as an additional source of plant nutrition.

Due to the above-mentioned factors, our formulations are more effective than the ones, produced by our competitors, even if they have a little higher concentration of an active ingredient.

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

LURS® colofermin calcium contains water softener, therefore the use of plant protection products in the hard water (high content of Ca2+ and Mg2+) in conjunction with LURS® colofermin calcium does not reduce their effectiveness. Hardness salts are reliably bound by the formulation component, without causing turbidity of the spraying solution. There is no danger of the calcium sulphate (gypsum) formation, which can lead to breakdown of spraying machinery. When conducting treatments use а freshly mixed solution.

LURS® colofermin 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.
Due to its composition the microfertilizer can be applied in a wide range of temperatures, starting from +5° C.

It is recommended for use in conjunction with VIMPEL ®plant growth stimulator.
