Granular fertilizers comprising macronutrients and micronutrients, and processes for manufacture thereof

A method of preparing fertilizer granules, said method comprising:

• spraying water comprising dissolved solids on a mixture comprising fertilizer ingredients, said fertilizer ingredients comprising:
• (i) 28% to 60% (w/w) magnesium oxide;
• (ii) 20% to 42% (w/w) elemental sulfur;
• (iii) 6% to 18% (w/w) high swelling clay;
• and
• (iv) 2% to 7% (w/w) binders;
• and
• granulating said mixture during and/or after said spraying so as to form fertilizer granules.
