Micronutrient fertilizer LURS® colofermin potassium

LURS® colofermin potassium is a concentrated microfertilizer for foliar feeding in the critical moments of development of field, fruit and berry crops.
  • environmentally friendly, highly concentrated, liquid micronutrient fertilizer, convenient and safe to use;
  • due to the organic form it is better penetrated by the plant tissues and better consumed by the plant;
  • performs well with pesticides, growth stimulators, solutions of mineral fertilizers with a wide pH range (that is, those that are used on various types of soils);
  • does not contain nitrogen, thus making the fertilizer an ideal source of potassium at later stages of plant development.
In which cases it is necessary to add potassium?
  • chlorosis appears on the leaf tips (so called “marginal leaf burn”);
  • chlorotic areas acquire bronze and dark brown and die off.
Which crops require potassium the most?

  • potatoes
  • vegetables (cucumbers, tomatoes, carrot)
  • orchards and berries (apple, pear trees, strawberries, raspberries)
  • grapes
  • corn
  • sunflower

What to do if there is a lack of potassium?

Application of the micronutrient fertilizer LURS® colofermin potassium will help eliminate the potassium deficiency in plants.

LURS® colofermin potassium has a significant physiological effect on plants, namely:

  • increases plant resistance to ground frost;
  • reduces affection of crops by root blight and rust;
  • improves the flow of water to plant cells;
  • reduces evaporation process;
  • increases formation of sugars in leaves and their transition to other organs.

Application rates:

30 – 40 mL (vegetables and other crops), 40 – 50 mL (corn, potatoes), 50 – 60 mL (sunflower), 60 – 80 mL (grapes, orchards and berries) pro 10 L of water.


Does not crystallize. Storage at low temperatures may result in the product gelling. Increase of ambient temperature causes the increment of the liquid viscosity. The composition of the microfertilizer allows conducting treatments at an air temperature above + 5°С.

For optimal effect, it is recommended to use in conjunction with the VIMPEL® plant growth stimulator.
