<P>PROBLEM TO BE SOLVED: To provide a microorganism carrying material avoiding the environmental conservation problem of the residue of carrier in an extended slow-acting fertilizer, keeping sufficient water-absorption and water retention, developing good fermentation culture property in the production of extended slow-acting fertilizer, and giving an extended slow-acting fertilizer exhibiting excellent performance as a fermentation material such as the decomposition and composting of organic materials. <P>SOLUTION: The purpose can be achieved by a microorganism carrying material prepared by impregnating an organic carrier obtained by mixing a cellulose sponge having an apparent density of 0.025-0.05 [g(dry)/cm<SP>3</SP>(wet)] with a cellulose sponge having an apparent density of 0.025-0.05 [g(dry)/cm<SP>3</SP>(wet)], preferably a cellulose sponge, in an amount of ≥5 wt.% in dried state with an aqueous solution of microorganisms, and carrying out the fermentation culture of the microorganism. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
