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