Today, the plant is one of the most important production sites for COMPO EXPERT products in Europe. The production focuses on the top fertilizer lines Floranid®Twin, NovaTec® and Blaukorn® from COMPO EXPERT.

It also produces coated fertilizers like Basacote® and liquid fertilizers like Basfoliar® or Vitanica®. The plant covers an area of around 18 hectares and is located in the Rhine port of Krefeld. It has its own railway access, so that all three major modes of transport for fertilizer – ship, truck and train – can be optimally used in Krefeld.

Combined with the existing logistics options, we can offer our customers optimal and fast delivery.
