Mineral fertilizers

NPS

Complex fertilizers - two-three and more nourishing elements in one granule.  Universal water soluble fertilizers.

Advantages:

  • the necessary nutrients are introduced in the soil all together;
  • ensures a more evenly absorption of nutrients from plants;
  • a favorable influence on the microbiological activity of the soil;
  • less expenditure of money and effort.

In the production is used ammonium nitrate and ammonium sulphate, the source of 6% S - related to the formation of chlorophyl; it neutralizes the chlorate ion and serves as an additional nutrient.

It shall be applied in the pre-sowing period or with the main soil treatment.
