NPK Mg 4-10-22 + 0.2 Zn


Corn NPK 4-10-22 + 0.2 Zn

It is a fertilizer that can be used for all crops. However, it is primarily intended for the fertilization of maize, due to the right proportions of phosphorus to potassium and contained in it additional macro and microelements. The sulfur content guarantees proper use of nitrogen, while the addition of magnesium taking part in the photosynthesis process ensures the growth of green mass with good nutritional values for animals. Nitrogen should be topped up in the form of appropriate nitrogen fertilizers according to the requirements of the fertilized plant.

amofoska® Corn NPK 4-10-22 is a good fertilizer for plants that need an increased dose of potassium, e.g. beets, potatoes, grassland. In addition, due to the sulfur content, its use is recommended for rapeseed, mustard, legumes and brassicas.

The high quality of the granules, i.e. the uniform grain size and the uniform composition of each granule facilitates even sowing. ANDmofoska® Corn NPK 4-10-22 is a granular, multi-component NPK fertilizer with the following nutrient content:


  • 4% N total nitrogen in ammonium form,
  • 10% P2ABOUT5 phosphorus pentoxide soluble in mineral acids (total); at least 6% P2ABOUT5phosphorus pentoxide soluble in neutral ammonium citrate and water, 5% P2ABOUT5 phosphorus pentoxide soluble only in mineral acids, at least 3% P2ABOUT5 phosphorus pentoxide soluble in water,
  • 22% K2For potassium oxide soluble in water,
  • 4% CaO calcium oxide soluble in water,
  • 10% SO3 sulfur trioxide soluble in water,
  • 0.10% B total boron,
  • 0.20% Zn zinc.

Microelements (Co, Cu, Fe, Mn, Mo) derived from natural phosphates are a valuable addition to the fertilizer improving the bioavailability of other ingredients. Boron and Zn microelements involved in reproductive processes, cause good grain quality and proper graining in corn cobs. The addition of these micronutrients in the fertilizer is particularly important on freshly limed soils and with a high level of fertilization.

The NPK fertilizer does not contain harmful amounts of heavy metals such as arsenic, cadmium, lead and mercury and is therefore safe for the environment.

amofoska® Corn NPK 4-10-22 + 0.2Zn is a typical pre-sowing fertilizer, which after sowing on a roll must be mixed with the soil. You can start seeding 3-5 days after spreading the fertilizer. The green manure should be spread in early spring. It is suitable for all soils, irrespective of their compactness and degree of acidity, especially recommended for use on soils with low potassium content.

The main component of this fertilizer is potassium and its doses should be determined according to the demand of fertilized plants for potassium and according to the potassium content available in the soil. The proportion of phosphorus to potassium ensures sufficient phosphorus fertilization of all plants.

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 early spring and after another swath or grazing pasture, 60 kg N / ha should be additionally applied.
