NPK 12:12:17 (SOP)

Nitrogen (N) is in ammoniacal form and is directly absorbed and incorporated into the organic matter of the plant, and at the same time it is more resistant to losses in the soil.

Potassium (K) in the formulation contributes to a better tolerance of plants to stressful conditions, more efficient regulation of water balance and carbohydrate circulation and enables the achievement of a high and high-quality yield.

The Supreme product line is being developed in the direction of enriching its formulations with carefully selected microelements.

What does NPK 12:12:17 (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.

NITROGEN (N) total 12%
Ammoniacal nitrogen 12%
PHOSPHORUS PENTOXIDE (P2O5) soluble in NAC and in water 12%
Phosphorus(V)oxide (P2O5) water-soluble 10,5%
POTASSIUM OXIDE (K2O) water-soluble 17%
Magnesium oxide (MgO) total 2%
Sulfur (S) water-soluble 14%
Boron (B) total 0,02
Zinc (Zn) total 0,01

By applying 12:12:17+ 2% Mg + 14% S + 0,02% B + 0,01% Zn (SOP) formulation you enable additional secondary macro- and microelements to complete plant nutrition, ensuring high yields and exceptional product quality

Why to apply NPK 12:12:17 (SOP)?

  • Excellent solution for plant species that have an increased need for potassium (K)
  • Phosphorous component (P) of high water solubility in a suitable form for absorption
  • Potassium (K) is in sulfate form (SOP), which makes the product an excellent solution for use in crops sensitive to chlorine (Cl)
  • Sulfur (S) has a positive effect on protein synthesis, it stimulates the enzymatic activity of plants and plays an important role in nitrogen (N) metabolism
  • The presence of zinc (Zn) and magnesium (Mg) promotes the synthesis of plant hormones (auxin), chlorophyll and carbohydrates, while boron (B) has a positive effect on flowering and fertilization

Elixir Zorka mineral fertilizers

Using the Supreme line 12:12:17 and 11:12:18 in the TV show Bolja zemlja


Grape vines belong to the group of plants that have an increased need for potassium (K) as one of the basic elements.


When fertilizing young plants, it is important to provide harmonious nutrition, so that the plants develop properly and grow until full fruit bearing, and special emphasis should be given to nitrogen (N) in these early stages.


For the successful production of potatoes, the balance of mineral nutrients in the soil is very important. High yields cannot be achieved on plots where certain mineral elements are missing


Raspberry is a plant that requires the most potassium (K) during flowering, fruit formation and fruit development. Therefore, fruit bearing raspberry plantations need to be fertilized every year with NPK fertilizers that have an emphasis on potassium (K).


From the point of view of applying nutrients to onions, the greatest needs are in potassium (K) and nitrogen (N), and slightly less in phosphorus (P), therefore, accordingly, you should choose formulations that have an emphasis on potassium (K) and that contain sulfur (S)


Strawberries, like raspberries, require the most potassium (K) during flowering, fruit formation and fruit development, and they need to be fertilized with formulations that emphasize this very element.


Intensive production and good yields of garlic require timely and high-quality execution of all agrotechnical measures. The needs of garlic in nutrients are mostly related to nitrogen (N) and potassium (K) and somewhat less to phosphorus (P).


During the exploitation period, blueberries require the application of mineral fertilizers with an emphasis on potassium (K). The fact that blueberry belongs to the group of plants sensitive to chlorine (Cl), indicates the need to use potassium in sulfate form.


Increased requirements for potassium (K) also determine the choice of formulation that should be applied in the production of watermelons.

Sour cherry

In the phase before planting sour cherry trees, potassium (K) and phosphorus (P) should be introduced in sufficient quantities based on agrochemical analyses. While by applying basic fertilizers in the fruit bearing period, we maintain their nutrient content in the soil.

Webinar – Tobacco fertilization technology

Fertilizers with a lower or no nitrogen (N) content, with an optimal phosphorus (P) content and a higher potassium (K) content showed excellent results in tobacco fertilization

Webinar – Potato fertilization technology

With its root system and tubers, potatoes leave the soil loose and clear of weeds, so it is a very good prerequisite for many crops

Webinar – Tomato fertilization technology

Tomato is a perennial plant in its natural habitat, but it is grown as an annual

Webinar – Paprika fertilization technology

Due to its economic importance and its use in human nutrition, paprika is now grown all over the world

Webinar – Raspberry fertilization technology

Intensive and modern raspberry production involves a series of agrotechnical measures, of which fertilization is one of the most complex.

Elixir Basic

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.

Elixir Premium

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 Micro Gran

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.
