Product Data Sheets

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.

Suitability for Organic Farming

K+S's plant nutrients are extracted from natural underground deposits of crude salt. They were formed many millions of years ago when primeval seas evaporated. Today, the salt layers are covered by several hundred meters of rock. They are mined by K+S and processed above ground into our products.

Due to the natural raw materials and the minimal processing effort required for further processing, many K+S products are ideally suited for organic farming and are approved for organic farming in accordance with EU Regulation 2018/848 and EU Regulation 2021/1165.
