Product information

PatentKALI is a highly concentrated complex fertilizer with potassium, sulfur, and magnesium.

  • Practically chloride-free (max. 3% Cl) and therefore particularly suitable for demanding special crops.
  • Round granules with particularly good spreading properties even for large spreading widths.
  • Contains all nutrients in a rapidly water-soluble and fully plant-available sulfatic form from natural origin (kieserite).
  • Extracted from natural crude salt deposits in Germany.
  • Approved for use in organic farming according to Regulations (EU) No. 2018/848 and (EU) No. 2021/1165.
  • Ideal K-Mg ratio for potatoes, fruits, and vegetables.
  • Potassium improves tolerance to drought stress.
  • Magnesium increases root growth.
  • Sulfur is essential for protein synthesis.
  • Acts independently of the pH value of the soil and does not change it.
  • No risk of soil salinization during drought due to low salt index.
  • As a straight fertilizer or for further processing in low-chloride premium bulk blends.
