PK 15:30

Complex, solid, mineral fertilizer characterized by highly water-soluble phosphorus (P) and potassium (K) in sulfate form (SOP)

A product of the SUPREME line characterized by a high concentration of active matter, with emphasized potassium (K) and the presence of the secondary macroelement sulfur (S).

The phosphorus component (P) is of high water solubility.

Potassium (K) is sulfate-based (SOP), which makes the product an excellent solution for use in crops sensitive to chlorine (Cl).

The emphasized content of potassium (K) affects the more efficient regulation of the water balance and the turnover of carbohydrates, which ensures the achievement of high and high-quality yields.

Sulfur (S) has a positive effect on the synthesis of proteins, oils, carbohydrates, enzymatic activity of plants, as well as their tolerance to stressful conditions of the external environment and the attack of pathogens.

What does PK 15:30 (SOP) contain?

The uniform ratio of nutrients in each granule and the high accessibility of nutrient elements enable easy uptake and uniform growth of plants.

Phosphorus(V)oxide (P2O5) soluble in NAC and in water 12%
Phosphorus(V)oxide (P2O5) water-soluble 11%
POTASSIUM OXIDE (K2O) water-soluble 30%
Sulfur (S) water-soluble 11%

By applying PK 15:30 + 11% S formulation you enable the cultivated plants to grow quickly and uniformly and to provide greater physical stability of the crop

Why to apply PK 15:30 (SOP)?

  • Each granule contains exactly the same ratio of nutrients
  • High water solubility of phosphorus (P)
  • Suitable formulation for plant species that have an increased need for phosphorus (P), especially potassium (K)
  • It contributes to achieving high, stable and quality yields
  • It ensures a continuous and targeted supply of plants with highly accessible nutrients

By applying the formulations from the BASIC line, you enable the cultivated plant species to grow quickly, uniformly and with greater physical stability of the crop. Such plants are much more tolerant to unfavorable climatic influences, achieve higher, more stable yields and ensure safety in agricultural 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.

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.
