抄録: As the result of fertilizer and feed importation the region has lead to material imbalance. A possible measure to alleviate this situation is to reduce the use of chemical fertilizers and promote the intra-regional circulation of substances by returning livestock excreta, raw garbage, and human waste to agricultural fields. In this study we presumed the use of liquid fertilizer as nitrogenous fertilizer,based on the scenario that we use the compost from organic wastes as priority and aim the trial'calculated demand'and'supply balance in Nagasaki prefecture. The result was as follows. When each compost and liquid fertilizer is used individually, the supply leeds to excessive in many areas, while in the scenario of standardized of compost volume and liquid fertilizer is used as nitrogenous fertilizer,the entire volume organic waste generation can be returned to agricultural fields, except for some areas. This indicates that it is important to design a system to use multiple recycled substances combined, in order to promote the intra-regional circulation of organic waste.
