EC FERTILIZER • GRANULATED • TYPE B.1.1.
NPK (Mg, S) 3,5-7-25-(2,5-19,5)

  • recommended especially for potato fertilization
  • particularly recommended for soil low in potassium, with medium level of phosphorus and without organic fertilization applied
  • shows very good effect on the quality of bulbs and starch content, thanks to the presence of potassium sulphate
  • very good spreading properties
  • contained micro-nutrients improve availability of other components
