Vervactor® Mineral Potassium Fertiliser

Vervactor® mineral potassium fertiliser is a modern granular fertiliser. The high proportion of potassium in combination with sulphur and calcium, as well as with magnesium and sodium, means that the fertiliser has a broad spectrum of coverage of the plant nutritional needs. As a result, Vervactor® accelerates plant growth and the quality of the tissues that form, while the stimulated root system enhances nutrient transport capacity. Vervactor® mineral potassium fertiliser activates the plant’s photosynthetic processes, carbohydrate, fat, and protein synthesis, and supports the plant thermal resistance. Due to the potassium contained in the fertiliser, the plants accumulate provitamin A and vitamins B1 and C, and the quality of the accumulated sugars also improves. In turn, the contribution of sulphur activates the detoxification of heavy metals and xenobiotics. Vervactor® is a versatile solution combining high activity with safety for crops!

 High proportion of potassium in combination with sulfur and calcium with magnesium

Reduced content of toxic chlorides only 16.5% (potassium salt 46%)

For use before sowing and top dressing, on agricultural and vegetable crops

High solubility and extended availability to plants

No effect of salinity and acidification of the soil

Patented formulation

Vervactor Granules
  • source of readily available, fully soluble potassium in the sulphate-chloride form
  • broad spectrum coverage of plant nutrient requirements, balanced proportion of sulphur and calcium with added magnesium
  • gradual release of nutrients and prolonged availability
  • granulate for pre-sowing and post-sowing application, excellent spreading ability
  • full solubility, no salinizing or acidifying effect on the soil
  • for agricultural and vegetable crops
  • G2D Nodens Technology ™ – a multi-stage technology of atomisation, separation, mixing and aggregation of active particles (together with an activator of their decomposition) due to which the product has the highest performance and allows significant savings in fertilisation
