  • Poor in chloride, especially suitable for use in horticulture
  • Classic fertilizer - without upgrading technology
  • Rich in potassium, for crops with high K demand or soils with poor K supply
  • Moderate in phosphate, for use in plants with moderate P
  • A high proportion of phosphate is immediately available to plants
  • The fine granulation allows a uniform distribution in the field


Complex granulated fertilizer with potassium sulfate (SOP) for basal and complementary dressings on chloride-sensitive crops and salt-affected soils.
For use in horticulture and special crops, outdoors and under glass.
Thanks to its uniform granulation, the fertilizer can easily be applied with spreaders or by hand. The distribution of nutrients is uniform, as each granule contains all the nutrients and micronutrients. Application is possible during the entire vegetation period.

Transport & Storage Recommendations


  • Deliver as loose goods in large bags or on pallets with bags and drums.
  • Protect bulk products from moisture during transport.
  • Protect goods from excessive direct sunlight and large temperature fluctuations during transport.
