A process for the production of elemental sulphur-urea fertilizer products is described, comprising the preparation of molten urea; preparing a suspension of micronized sulphur particles with water; mixing the molten urea with suspension of micronized sulphur particles with water wherein the micronized sulphur particles substantially remain in micronized solid state; and spraying the mixture of molten urea and suspension of micronized sulphur particles with water into a granulator, wherein the water in the mixture is flashed off, resulting in the formation of sulphur-urea granules with an even distribution of urea and micronized sulphur particles. An elemental sulphur-urea fertilizer composition obtained by the process is also described.

A fertilizer stick comprising a saccharide and a fertilizer dispersed therein, wherein the saccharide constitutes about 25% to about 95% (w/w) of the stick.

A fertilizer blend containing 10 wt. % to 90 wt. % of a first particulate fertilizer composition and 10 wt. % to 90 wt. % of a second particulate fertilizer composition is disclosed. In the fertilizer blend, the second particulate fertilizer composition can be blended with the first particulate fertilizer composition. The first particulate fertilizer composition can include a core containing a binder, a pH buffering agent, and an urease inhibitor, and a shell containing urea, where the shell covers at least a portion of an outer surface of the core.
