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.
