The high nitrogen content of the complex fertiliser NPK (S) 20-5-10 (31) allows it to be used in a wide range of annual crops that have significant needs in the early stages of cultivation, such as various horticultural crops, spring cereals or woody crops in contributions to the winter output.

Furthermore, the inputs of boron and iron represent quality and performance factors required in almost all agricultural productions.

Nitrogen: A determining factor in the growth and development of the plant. It is also the essential component in proteins

Phosphorus: It favours root development and adds vigour to the crop. It is a component of nucleic acids and lipids. It is also very important in the transfer of energy.

Potassium: It increases the crops' resistance to cold and drought. It is essential for the metabolism, photosynthesis and the activation of enzymes.

Sulphur: A component of amino acids, vitamins, proteins. Increasing deficiencies due to low levels in soils. It also regulates the availability of nitrogen and mobilises phosphorus and potassium, and soil micronutrients.

Form of application

It is advisable to apply NPK complex fertilizers homogeneously on the surface of the soil and, if possible, dig them in so that they get near the roots. This facilitates the absorption of phosphorus and potassium, which are elements that are not very mobile.

In the case of tree crops, it can also be located between the rows.

It is recommended that all NPK complex fertilizers are applied:

  • Shortly before sowing in the case of herbaceous crops.
  • At least one month before sprouting in the case of tree crops, or in other words, far enough in advance before the plant needs the nutrients that we supply.
