A method for producing solid fertilizer from liquid manure or from sludge includes mixing the same with harvest leftovers. The liquid substance (manure, sludge) is intimately mixed with the harvest leftovers during grinding. The solids are ground to a particle size of a few microns. The particles adsorb and absorb the liquid substance fully, so that a solid fertilizer product results which neither smells nor endangers the ground water. All of the valuable materials from the liquid substance and from the harvest leftovers are retained in the finished product, which is a high potency fertilizer. The fertilizer can be applied with methods and devices which are conventionally used in agriculture. An apparatus for performing the method includes a grinder/blender which is supplied independently from a harvest leftover storage and from a liquid substance storage. The materials are measured for exact mixture and the pH value may be adjusted.
