A process for preparing water-soluble granules of amnionic glyphosate comprising: a) addition of glyphosate acid to a Broensted base which supplies ammonium ions in a molar ratio base/acid comprised between 0.8 and 1.1； b) homogenization of the mixture prepared in a)； c) addition of one or more surfactants in amounts in the range 5%-50% by weight based on the glyphosate acid； d) mixing of the mass prepared in c) for a time lower than about 10 minutes until obtaining an extrudable mass； e) extrusion of the mass obtained in d)； f) drying until obtaining a granule having a residual moisture lower than 1%.
