Mineral fertilizers
NPK
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.
