Zusammenfassung:PROBLEM TO BE SOLVED: To provide an apparatus for feeding a solid organic matter decomposition type liquid fertilizer that efficiently feeds a nutrient and avoids environmental deterioration by solid organic matter.SOLUTION: The apparatus for feeding the solid organic matter decomposition type liquid fertilizer includes a first elution water tank 3 for eluting iron fulvate in water, a second elution water tank 4 that decomposes solid organic matter in polluted water by a massive cleaning material 20 put inside the tank and prepares a nutrient liquid fertilizer and an elution component-containing water feeding apparatus that selects elution component-containing water in one or both of the elution water tanks of the first elution water tank and the second elution water tank and supplies the water to the sea and supplies the elution component-containing water to the sea. The second elution water tank is arranged so that an aerobic region in which oxygen-containing bubbles rise in water and an anaerobic region apart from the aerobic region alternately appear in the middle of a flow, a cleaning zone is filled with a massive cleaning material, polluted water is alternately passed through the aerobic region and the anaerobic region while being brought into contact with the massive cleaning material in the middle of passing the cleaning zone to decompose solid organic matter in sludge water.
