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.

Storage Info

The product should be stored in a dry place and covered with a plastic tarpaulin to protect it from humidity. When storing loose goods, steel girders and supports should be protected against corrosion, and the floor as well as the walls should also be provided with a protective coating. Walls and roof beams made of wood have proved to be particularly resistant.
