<p>PROBLEM TO BE SOLVED: To provide a fertilizer formed by decreasing the amount of the cadmium included in the internal organs, etc., of cuttlefishes by mixing of culture media, soot, etc., and effectively utilizing the internal organs of marine products, such as the internal organs of the cuttlefishes without hazard. SOLUTION: Calcium carbonate:soot:rice bran: culture media are mixed at ratios of 10:1:1:1. The mixture obtained by mixing at the ratios described above is added to the internal organs of the cuttlefishes regulated to 30 to 40 wt.% of the total weight of the mixture and is sufficiently mixed. The mixture is thereafter piled and matured in a house for about three months to cause fermentation and drying, by which the fertilizer reduced in the cadmium content to 2.6 mg/kg is obtained.</p> |
