A microbial additive containing artificial soil for green roof and a method for promoting plant growth using thereof

The present invention relates to a rooftop afforesting artificial soil including a microbial formulation, and to a method for producing the same. More specifically, the present invention relates to a microbial formulation including a Nocardioides sp. DAEJI-12 strain which is an actinomyces isolated from muck peat and having an excellent lignin decomposing function and an excellent antagonic ability with respect to plant pathogenic mold; a rooftop afforesting artificial soil including the same; a method for producing the same; and a method for afforesting a rooftop by promoting the growth of a plant by using the rooftop afforesting artificial soil. The rooftop afforesting artificial soil including such a microbial formulation changes physicochemical properties to be suitable for the growth of a plant, thereby promoting the growth of a plant and inhibiting plant pathogenic mold.
