Introduction
In many places of Japan, farmers started anic farming approximately 50 years ago.
Following developments in the society gave rise to the “organic” movement:
(1) Social background in anic farming was initiated
a As petrochemical industries developed rapidly, soil and water were contaminated by

these chemicals in food and drinking water, too.
b Modern farming system heavily dependent on chemicals such as fertilizers,
