NPK 4-12-12 + 2.5 mg


NPK 4-12-12 + 2.5 mg

NPK 4-12-12 + 2.5 MG in relation to the ratio of phosphorus to potassium (P2ABOUT5K2O = 1: 1) qualifies for pre-sowing application for spring and winter crops. Due to the sulfur contained in the fertilizer, it is recommended to use it for the cultivation of rapeseed, legumes and grassland. Magnesium contained in amofoska® improves the quality characteristics of crops, including fodder collected from grassland, increasing the magnesium content necessary for animal health in the sward.

High quality of granules, i.e. uniform grain size, uniform composition of each granule and no dust facilitates uniform sowing. Amofoska NPK Mg 4-12-12 + 2,5 is a granular multi-component NPK fertilizer with the following nutrient content.


  • 4% N ammonium nitrogen (total),
  • 12% P2ABOUT5 phosphorus pentoxide soluble in mineral acids (total), at least: 9% P2ABOUT5 phosphorus pentoxide soluble in neutral ammonium citrate and water, 6% P2ABOUT5 phosphorus pentoxide soluble in water,
  • 12% K2For potassium oxide in the form of water-soluble potassium chloride,
  • 10% CaO calcium oxide soluble in water,
  • 15% SO3 sulfur trioxide soluble in water,
  • 2.5% MgO magnesium oxide (total).

Micronutrients (Co, Cu, Fe, Mn, Mo, Zn) derived from natural phosphates are a valuable addition to the fertilizer improving the bioavailability of other ingredients.

Sulfur contained in the fertilizer in easily digestible form is a valuable nutrient for high-protein and sulfur-loving plants. According to the current criteria, this fertilizer does not contain harmful amounts of heavy metals such as arsenic, cadmium, lead and mercury, so it is safe for the environment.

amofoska® NPKMg 4-12-12 + 2.5 is a typical pre-sowing fertilizer. After spreading the soil, it is necessary to mix the fertilizer with the soil. Sowing of seeds can be started after 5-7 days from the date of mixing the fertilizer with the soil. The green manure should be spread in early spring. This fertilizer is suitable for all soils, regardless of their compactness and degree of acidity.

The dosage of Amofoska NPK 4-12-12 + 2.5 Mg was given to soils with a low average and high content of phosphorus and magnesium, with an average or high content of potassium in the soil. The component according to which the amount of fertilizer should be determined is phosphorus. Its height depends on the soil's richness in this nutrient and the needs of the plant being cultivated.

The doses given in the table are approximate and should be modified depending on the expected yield. This fertilizer can be used in early spring for grassland in a dose not exceeding 400 kg of fertilizer per ha. In addition, nitrogen should be used, preferably the ammonium nitrate or Puławy ammonium nitrate, after another mowing or grazing pasture.
