PURPOSE:To obtain an organic composition capable of preventing soil blights particularly caused by continuous cropping injury with economic and stable effects, by using photosynthetic bacterial cells, e.g. bacterial cells of purple non-sulfur bacteria, etc., and plant extraction residues or general waste water treatment sludges in combination. CONSTITUTION:An organic composition obtained by using bacterial cells of photosynthetic bacteria, (e.g. bacterial cells of purple non-sulfur bacteria or excess sludges of water water treatment utilizing the purple non-sulfur bacteria can be directly used) and plant extraction residues, e.g. residues after removing industrially available glycyrrhizin, gall, tannin, etc., from plant bodies, residues after extracting coffee, black tea, etc., in combination. Furthermore, actinomyces, bacteria and yeasts having competitive action on the above-mentioned pathogenic germs may be contained. The above-mentioned composition is preferably prepared by preparing granules using a pulverized waste bed log for SHIITAKE mushrooms. |
