Special Customized Phosphate Fertilizer Products and Composites from Phosphorus Recovery

Clever combinations of phosphate fertilizers for special applications

Avoid the double work by seeding first and then fertilizing. Improve the seed germination ability and the harvest yield. Benefit from PHOS4green technology to combine the seed with the required nutrients to create a ready to use high performance seed. The fertilizer granules can be coated directly with biocides, insecticides or fungicides or can be produced as homogeneous granules with these additives dispersed throughout the granule. Coating with biopolymers enables controlled release of the plant nutrients or pesticides.

Glatt uses its many years of experience in the production of special fertilizers to to deliver technology for long-term fertilization, multi-component fertilization and controlled release or slow release fertilizer granules. Homogeneous multi-component fertilizers can be produced particularly efficiently by fluidized bed spray granulation. In this process, the precisely adjusted multi-component mixture is processed directly from the solution into compact granules. Further functionalization can then be achieved by fluidized bed coating.

Careful formula development and precise process control enable the production of completely closed coatings with thin outer shells/layers. The application of different enveloping materials by means of fluid bed coating makes it possible to further adjust the granule’s properties. The original bulk properties of the fertilizer granules remain virtually unchanged.

The coating of the fertilizer granules is carried out in compliance with the current regulations of the Fertilizer Ordinance (German Düngemittelverordnung (DüMV) and Regulation EG No. 2019/1009). Conformity with some of these requirements is sometimes only achieved through the use of such coating materials.

Some fertilizer product examples:

Grain seed coated with a protective layer using Glatt fluid bed technology

Fertilizer granules with a delayed release coating using Glatt fluid bed technology

Fertilizer granules before and after coating with an insecticide coating layer using Glatt fluid bed technology
