<p>The invention relates to a method and also a device for production of a fertilizer precursor or of a fertilizer. The method comprises in this case the following method steps: a) production of an acidic starting solution (05) in which at least one organic acid is present in dissolved form; b) addition of the acidic starting solution (05) to at least one mineral-containing substance; c) artificial weathering by the starting solution of the minerals present in the mineral-containing substance. The device for producing organomineral fertilizer comprises at least one device for providing an organomineral compound or a mineral-containing substance, at least one device for at least one mechanical preprocessing of the organomineral compound and at least one solution storage device (50) which has an outflow device (51) which makes possible an outflow of an acidic starting solution (05) onto the provided mechanically pretreated compound, wherein an addition of the acidic starting solution (05) to the compound triggers at least the technical weathering of the minerals present in the substrate.</p> |
