An improvement in the manufacture of granular phosphono-fertilized fertilizers, characterized in that it consists of starting from a phosphated raw material consisting of a superphosphate in a divided solid state - which eventually contains an excess of acid, without however this excess being sufficient to make it lose its consistency of divided solid - it is said matter, constantly subjected to agitation, firstly by the fraction of the amount of ammonia that is desired to introduce in the fertilizer, and then by sulfuric acid in an amount lower than that which would take the material to the pasty state, in treating again the mass by the ammonia, and so on alternating the supply of ammonia and sulfuric acid until the total amount of nitrogen desired has been incorporated into the fertilizer.
