Abstract

Magnesium sulfate granulates contain at least 90 wt. % synthetic magnesium sulphate hydrate with respect to the total mass of the magnesium sulphate granulate, and have a dry loss of less than 2 wt. % determined by drying of the granulate for 2 hours at 105° C. and 1 bar. Further, a method is used for producing said magnesium sulfate granulates and to their use in urea-containing fertilizer compositions.
