SPOLSAN® industrial fertiliser
SPOLSAN® (ammonium sulphate)

Industrial fertiliser, a crystalline substance that is white to whitish-grey, sometimes pinkish-grey, a by-product of caprolactam production. In recent years, especially in connection to the desulphurisation of power plants, ammonium sulphate has become an increasingly important fertiliser containing sulphur and ammoniacal nitrogen. It is used for direct fertilisation or as a raw material to produce mixed fertilisers containing sulphur.


SPOLSAN® G (granulated ammonium sulphate)

Granulated industrial fertiliser, created during caprolactam production and containing nitrogen in ammonium form and sulphur in the form of sulphate ion. It also contains a small dose of ammonium nitrate, the concentration of which does not exceed 1.5%. Used for direct fertilisation.
