PRODUCTION OF FERMENTED FERTILIZER USING CULTURE RESIDUE OF MUSHROOM BED CULTURE MUSHROOM AND ORGANIC MATERIAL OR THE LIKE AND METHOD FOR CALCULATING FERTILIZER COMPONENT AFTER FERMENTATION

摘要

PROBLEM TO BE SOLVED: To produce a fertilizer which is nearly neutral in pH by simplifying moisture regulation in production of the organic fermented fertilizer, obviating the generation of an ammonia smell in a production process and making production indoors in a short period of time and to obtain a simple method for calculating the contents of nitrogen, phosphoric acid and potassium after fermentation. ;SOLUTION: The culture residues of the mushroom bed culture mushrooms discharged from factories are used as the materials for the organic fermented fertilizer and are rested outdoors under conditions under which the materials are kept free from rainwater until the moisture content attains 45 to 50%. The materials are mixed within a room where air flows. The materials are turned at the fourth day and the seventh day. The materials are spread and air dried after 10 days. Thermophilic microorganisms which do not die in spite of the generation of fermentation heat of ≥60°C are used for the microorganisms. The fertilizer components after the production are analyzed and the change ratio of the component quantities during the fermentation are calculated.;COPYRIGHT: (C)2000,JPO
