Abstract

Granular NPK-fertilizers are prepared by granulating a liquid mixture obtained by adding a solid, particulate potassium salt to a liquid ammoniumnitrate containing phase, which either contains ammoniumphosphate or to which this is not added. <??>The potassium salt particles have an average size no greater than 55 mu , while less than 1%wt are larger than 150 mu , and are added at a temperature between 5 and 40 DEG C. <??>The resulting granules show an excellent storage-stability.
