NOVELTY - Production of soil conditioner, involves placing chaff inoculated with Actinomyces in fermentation tank, and carrying out fermentation. A large amount of Actinomyces is used as microbial source in culture medium comprising chaff. The microbial source is added with respect to the base material of Actinomyces compost, such as crushed piece or chaff of wood chip, sawdust, and used microbial bed, such that the ratio of microbial source is 90-70% and base material is 10-30%.    USE - Production of soil conditioner.    ADVANTAGE - The inoculation of Actinomyces is carried out reliably in short time. The manure without bad smell can be obtained in few days. The soil conditioner has excellent handleability. The property of tilled soil is improved.    DETAILED DESCRIPTION - Production of soil conditioner, involves placing chaff inoculated with Actinomyces in fermentation tank, and carrying out fermentation. A large amount of Actinomyces is used as microbial source in culture medium comprising chaff. The microbial source is added with respect to the base material of Actinomyces compost, such as crushed piece or chaff of wood chip, sawdust, and used microbial bed, such that the ratio of microbial source is 90-70% and base material is 10-30%. The base material is placed in large-sized fermentation tank (provided with stirring apparatus) containing microbial source. The base material and microbial source are mixed by the operation of the stirring apparatus. Subsequently, the mixture is left to stand, and then subjected to fermentation for 48 hours, stood for 6 hours, and intermittent working of the stirring apparatus is carried out at 10 part grade (sic), where ventilation is provided by stirring. Subsequently, the base material is taken out from the fermentation tank and deposited on a pile at compost yard. After leaving the base material to stand and allowing to fully ripen, the heap of the deposited base material is broken down, cooled and moisture content is evaporated, and Actinomyces manure is obtained.
