NPK 8:15:15

Complex, solid, mineral fertilizer that contains the necessary macroelements – nitrogen (N), phosphorus (P) and potassium (K) and secondary macroelements – sulfur (S) and calcium (Ca)

It is used in the production of a large number of plant species due to the specificity of the formulation and the uniform ratio of nutrients.

The presence of secondary macroelements sulfur (S) and calcium (Ca) affects nitrogen uptake, numerous enzymatic processes, protein synthesis, but also plant tolerance to stressful conditions.

Due to the calcium content, the formulation NPK 8:15:15 + 3% Ca +9% S is also suitable for soils with an acidic reaction.

It is recommended above all on soils with a uniform content of phosphorus (P) and potassium (K). It is characterized by good solubility and availability of phosphorus in the year of application.

What does NPK 8:15:15 contain?

Each granule is characterized by a balanced ratio of nutrients.

NITROGEN (N) total 8%
Ammoniacal nitrogen 8%
Phosphorus(V)oxide (P2O5) soluble in NAC and in water 12%
Phosphorus (V) oxide (P2O5) water-soluble 9%
POTASSIUM OXIDE (K2O) water-soluble 15%
Calcium(Ca) water-soluble 3%
Sulfur (S) total 9%

By applying NPK 8:15:15 + 3% Ca + 9% S formulation you enable the cultivated plants to grow quickly and uniformly and to provide greater physical stability of the crop

Why to apply NPK 8:15:15?

  • Good solubility and availability of phosphorus (P)
  • High efficiency in the application of the ammoniacal form of nitrogen (N)
  • The presence of secondary macroelements (S and Ca) has a positive effect on nitrogen (N) uptake, numerous enzymatic processes, protein synthesis and plant tolerance to stressful conditions
  • Economically acceptable formulation

Experiences of users of 8:15:15 formulation

Experiences in crop farming have shown that good results in the production of cereal grains are achieved using NP and NPK formulations with emphasized phosphorus (P).

Sunflower belongs to plants with an increased demand for potassium, so the production technology should include some of the formulations that have a higher proportion of potassium (K).

Adequate nutrient balancing in the soil is very important for the successful production of soybeans, where stable and high yields cannot be expected without the appropriate application of complex mineral fertilizers.

One of the basic prerequisites for achieving stable and high yields of rapeseed is balanced nutrition with mineral fertilizers with an emphasis on nitrogen (N) in the stages from the initial spring growth to flowering.

Bean plants need nitrogen from the soil, that is, from fertilizers, at the beginning of the growing season until nodules are formed on the roots. Also, the presence of phosphorus (P) and potassium (K), which are absorbed most intensively in the flowering phase, is very significant.

Wheat is the basic bread crop that feeds about 70% of the planet’s population today

Webinar – Corn fertilization technology

Applying an adequate amount of fertilizer ensures the smooth growth and development of the plant and affects the height and stability of the yield.

Webinar – Sunflower fertilization technology

Sunflower is characterized by a strong root system and uses nutrients from deeper layers

Webinar – Soybean fertilization technology

Soybean production is not too demanding and can be mastered very easily

Webinar – Rapeseed fertilization technology

At the world level, together with soybean, palm and sunflower oil, it makes up over 2/3 of the total oil production

The microelements with which the PREMIUM line is specially enriched are highly water-soluble and easily available to plants. By using these formulations, you additionally influence the proper growth and development of plants, thanks to primary and secondary macroelements.

What makes the SUPREME product line special is potassium (K), which is found in sulfate form (SOP) in most formulations. This production line is enriched with carefully selected microelements and is the best solution for specific plant crops and for all types of soil.

Elixir Zorka microgranulated starter fertilizers have a well-balanced ratio of nutrients: primary, secondary and essential microelements, which stimulate plant growth in the initial stages of development and contribute to better plant rooting.
