Abstract: A process for the manufacture of a urea-sulphur fertiliser composition, the process comprising providing feeds comprising elemental sulphur, urea, and optionally a surfactant, such as a multifunctional ionic surfactant; merging the feeds in order to obtain a combined feed; passing the combined feed through a mixing stage in order to obtain a mixed feed; and passing the mixed feed through a processing stage in order to obtain the urea-sulphur fertiliser composition. Compositions obtained by the process are also provided.
