  • free-flowing, fine crystalline powder, which dissolves quickly in water without any residues
  • Magnesium is a major component of chlorophyll, which is essential for photosynthesis
  • Sulphur is mainly important for protein metabolism and increases nitrogen efficiency resulting in a higher yield


  • Fertigation:
    It is recommended to apply in one or several treatments 25 kg/ha, in the case of severe deficiency and/or visible deficiency symptoms, the application rate should be increased up to 50 kg/ha applied in 2 to 4 splits.
  • Foliar application:
    is an excellent way to supply additional magnesium with Sulphate during critical physiological or environmental conditions
