NPK 7:21:21

Complex, solid, mineral fertilizer that, in addition to primary macroelements, also contains the secondary element sulfur (S) and the microelement zinc (Zn)

An excellent solution for plant species that have an increased need for phosphorus (P) and potassium (K).

The content of zinc (Zn) has a positive effect on the synthesis of plant hormones (auxin), chlorophyll and carbohydrates.

The presence of sulfur (S) affects protein synthesis, stimulates the enzymatic activity of plants, but is also crucial in the metabolism of nitrogen (N) in plants.

What does NPK 7:21:21 contain?

Each granule is characterized by a balanced ratio of nutrients.

NITROGEN (N) total 7%
Ammoniacal nitrogen 7%
PHOSPHORUS PENTOXIDE (P2O5) soluble in NAC and in water 19%
Phosphorus(V)oxide (P2O5) water-soluble 14,7%
POTASSIUM OXIDE (K2O) water-soluble 21%
Sulfur (S) water-soluble 4%
Zinc (Zn) total 0,05%

By applying NPK 7:21:21 + 4% S + 0,05% Zn formulation you enable the cultivated plants to grow quickly and uniformly and to provide greater physical stability of the crop

Why to apply NPK 7:21:21

  • High efficiency in the application of the ammoniacal form of nitrogen (N)
  • It ensures excellent utilization of nutrients during the growing season
  • It contributes to achieving high, stable and quality yields
  • It ensures a continuous and targeted supply of plants with highly accessible nutrients
