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.
