Information for farmers

Application standard: 1–30 kg/ha (of active material)

  • S = sulphur (consumed in form of ion SO42-;
  • Ca = calcium (consumed in form of ion Ca2+;
  • Mg = magnesium (consumed in form of ion Mg2+.
Sulphur

Second protein element

  • Sulphur deficit causes weak development which leads to a lower yield. Sulphur is necessary for the growth and development of every crop;
  • Plants consume a volume of sulphur equal to the volume of consumed nitrogen;
  • Sulphur is the basic element that increases protein and oil content in agricultural crops;
  • Improves resistance to:
    • diseases;
    • low temperatures;
    • dry weather.

Sulphur-sensitive crops:

  • Oil-bearing crops, grain crops, vegetables, rape, mustard, summer rape, corn, sunflower.
Calcium

Calcium is an important component of cell walls and an untegral component of chromosomes; its application helps to strengthen the stems of grain crops and reduces losses during roots storage.

In leguminous crops calcium takes part in sugar transportation process and organic acids neutralization process.

Calcium is the basic regulator of enzyme activity which in its turn secures the assimilation of other nutrients (especially nitrogen).

Calcium is essential for:

  • Root system growth;
  • Protection against damage during harvesting.

Plants are able to assimilate calcium from gypsum, lime and calcium chloride.

Calcium is usually applied together with lime on acid soils in order to reduce the toxic effect of aluminum ions in soil solution.

Crops that give positive reaction to calcium application:

  • Vegetables, fruits, berries, soy.
Magnesium

Magnesium is the central atom of chlorophyll molecule.


As it is the central atom of chlorophyll molecule, magnesium is responsible for turning carbon dioxide into organic compounds with emission of oxygen.

Light soils with a low content of exchangeable cations may not satisfy the demand of a plant for magnesium. In this case compounds of magnesium in the form available for plants are entered in the soil.

Magnesium plays a part in:

  • Nitrogen assimilation;
  • Protein accumulation.

Plants can consume and assimilate magnesium from various kinds of fertilizers:

  • Fast-response:
    • Magnesium sulphate;
    • Potassium-magnesium.
  • Slow-response:
    • gypsum (magnesium carbonate).

Crops sensitive to lack of magnesium:

  • grain crops, potato, soy.
