A fertiliser comprising both sulphur and a solution of urea and ammonium nitrate in water is disclosed. Processes for making such a fertiliser are also disclosed.

A fluidized bed reactor includes at least one granulation compartment with one or more air inlets, and at least one scrubber for cleaning air from the granulator, such as a wet scrubber and/or a dry scrubber. The reactor comprises a return line for recycling cleaned air leaving the scrubber to the air inlets of the granulation compartment.

Methods, systems, and apparatuses for coating a fertilizer material by contacting the material with a coating material and a solvent are disclosed herein. The coated material can be obtained by mechanically agitating the fertilizer material while contacting the fertilizer material with a coating material and a solvent. The coating material can be sprayed onto the fertilizer material during mechanical agitation. The coating process and apparatus can use a paddle mixer and can be configured to handle organic solvents used to carry the coating material.

The invention features a fertilizer mixture containing (i) a calcium ammonium nitrate mineral fertilizer and (ii) 2-(N-3,4-dimethylpyrazole)succinic acid, or a salt thereof.

Method and fluidized bed reactor for the production of granules, such as granules of urea or ammonium nitrate. The fluidized bed reactor comprises at least one granulation compartment with air inlets, and an air moving device downstream of the granulation compartment, e.g., downstream of at least one scrubbers. The air moving device is configured to draw air through said at least one air inlet into at least one granulation compartment.
