Comparison of environmental performance between conventional and organic roughage production: grass and silage maize.

摘要

Roughage production is one of the major factors contributing to environmental pollution. Therefore, whether the production of organic roughage reduces environmental loads compared with conventional production is an important issue in environmentally friendly organic milk production. Using the life cycle assessment method, we assessed the environmental performance of conventional and organic roughage production in Japan. The results of this article show that, in order to enhance environmental performance for organic roughage production in Japan, purchased organic fertilizers should be reduced because the nitrogen contained in them is responsible for environmental loads emitted by nitrogen loss.
