TECHNOLOGY FOCUS - AGRICULTURE - Preferred Additives: The pruning agent is sprayed at high temperature water vapor in to the pressure-crushed and pre-processed peat, dried product of livestock, carbonized material and return organic fertilizer.Preferred Method: 30-150 nl/minute of air is supplied for 1 m3 of organic waste, during primary fermentation. 10-20 nl/minute of air is supplied for 1 m3 of intermediate fermented material, is supplied and the supplied air velocity is 0.1-0.25 m/minute. The air is supplied using a pressure feed type intermittent control type. The amount of supplied air is adjusted by changing biological oxygen demand (BOD) value and fermentation increase temperature of organic waste or intermediate fermented material, so that the condition satisfies aerobic/anaerobic fermentation environment. The primary, secondary and tertiary fermentations are carried out in 7 days, respectively, totally 21 days in a room. The moisture content of the fertilizer is 15-30%, the BOD is 10 mg/g-DS or less, pH is 7-8 and the carbon content is 11-20%.    TECHNOLOGY FOCUS - BIOLOGY - Preferred Microorganism: The microorganism group contains filamentous fungi which forms extracellular enzyme, fermentation promoter containing effective microorganism group, aerobic and anaerobic bacteria, and Actinomycetes microbes. The above microorganism group decomposes hemicellulose, cellulose and lignin, into easy-decomposable substance, and initiate assimilation of carbon dioxide by photosynthesis, or synthesis of an organic compound. The filamentous fungi is Aspergillus, Mucor, Chaetomium, Fusarium, Myrothecium and/or Trichoderma. The microorganism group is bacteria or fungi belonging to genus such as Bacillus, Cellulomonas, Corynebacterium, Cytophaga chlorobium, Propionibacterium, Rhodospirillum, and Rhodopsuedomonas and white wood rotting fungi. The Actinomycetes are microbes belonging to genus such as Micromonospora, Nocardia, Streptomyces, Corynebacterium, Actinomyces, Sreptoverticilium and Rhodococcus.    TECHNOLOGY FOCUS - MECHANICAL ENGINEERING - Preferred Arrangement: A deodorizing apparatus continuing deodorant microbes which decomposes various components containing sulfur compounds such as methyl sulfide and methyl disulfide, methyl mercaptan, hydrogen sulfide in soil such as a kuroboku soil which particles like charcoal or bamboo charcoal, yellow soil or gray lowlands soil. The deodorizing is performed aerobically. ACTIVITY - Fertilizer.    MECHANISM OF ACTION - None given.
