Abstract

作物生産のための LCA 手法の確立に寄与することを目的とし,ブロックローテーション方式の輪作体系における農業機械作業による間接投入エネルギーおよび間接 CO<sub>2</sub> 排出量の各品目 1作・1ha 当たりの推定方法を提案した。本方法では,機械の汎用利用,耐用年数,自走式作業機と非自走式作業機の違い,作付品目の面積比率が考慮される。本方法を,北海道十勝地方のモデル農家に適用した結果,生産性や環境影響を評価するための基礎資料が得られた。

The purpose of this study is to help establishing the LCA method for crop production. Therefore, we suggest the method of proportional inference allocation to estimate the amount of indirect emissions of CO<sub>2</sub> as well as the indirect energy input, resulting from the application of agricultural machinery in the crop rotation based on block rotation, for each crop per hectare. In this method, the general use of the machine, service life of machine, the difference between propelled and self-propelled machines, as well as the area of the planted crop in the rotation are considered. By applying this method at the model farms of Hokkaido Tokachi, we could obtain basic data for evaluating the productivity and the environmental impact.
