To produce organic fertilizer which is effective for sterile agricultural land, a mixture comprising coral reef powder, domestic animal excreta, sewage disposal waste and ground cellulose derived from plant fiber is prepared and it is well mixed in the presence of organic compounds and inorganic salts. Thereafter, it is subjected to cultivating in a multi-bath type cultivating bath for a predetermined period of time while temperature and pH are adjusted properly. Cultivation is achieved with the addition of bacilli including nitrogen fixing bacillus such as Azotobactor vinelandii, Bacillus megaterum, Rhizobium leguminosarm or the like, Trichoderma virde acting as raw fiber decomposing bacillus, candida utilus acting as yeast fungus and green algae, each of which is cultivated under the operating condition of symbiosis cultivation. The pH in the cultivating bath is maintained in the range of 5.5 to 7.5, preferably in the range of 6 to 7. After completion of cultivation, the mixture is dried to form dried product and the latter is shipped to users. |
