PURPOSE:To obtain the org. fermented fertilizer which contains ample chitosans and is expected as a soil conditioner by mixing Crustacea, Insecta, shellfish, etc., with the humus obtd. after easily decomposable org. matter is subjected to a fermentation treatment by thermophilic bacteria and subjecting the mixture to an aerated fermentation treatment with soil bacteria of Heterotorph genus as media. CONSTITUTION:The living bodies, skins, shells, residues after processing, etc., of the Crustacea (e.g. crabs, shrimps, mantis shrimps), Insecta (e.g. beetles, silkworms, cockroaches, etc.), mollusk (e.g. hard clams, little clams, krills, oysters, cuttlefishes, etc.) are mixed in a figured state with the humus obtd. after the easily decomposable org. matter (e.g. cattle dung, sewer sewage, night soil sludge, food residues, fish scrap, etc.) is subjected to the fermentation treatment at >=70 deg.C. The soil bacterial belonging to the Heterotorph genus (more particularly radiation bacteria, such as actymonyces) are incorporated into this mixture and the mixture is subjected to the fermentation treatment under the supply of air, by which the org. fermented fertilizer contg. the amble chitosan components is obtd. |
