On the other hand, however, it has inevitably invited environmental disorder including underground water pollution, accumulation in salts, dysfunction of ecosystem and so on. Organic agriculture, which is a type of low input sustainable agriculture using organic materials, has therefore received worldwide attention. In our country, it was not until the beginning of the 1970s, before organic agriculture had been highlighted, when the risk of agricultural chemical reagents was recognized. Nowadays, the demands for organic agriculture are expanding in accordance with the increased number of allergy patients, the risk of O-157, dioxins, BSE as well as the social concern for food safety. The products of organic agriculture can be thought as an achievement of sophisticated technology combining the traditional agricultural techniques with modern agricultural techniques which make use of crop rotation and organic fertilizers to maintain soil fertility, natural enemies and/or companion plants to protect crops from pests and diseases. Thus, organic agriculture can be regarded as a sustainable material- recycling agriculture. In this report, we compared the effect of various organic and chemical fertilizers on the growth and quality of vegetables along with the physico-chemical characteristics of soil and discussed the possibility of organic fertilizers to be an alternative to chemical fertilizers in the future., E, 1, P, 総説, Review}, pages = {179--188}, title = {有機質肥料の機能性}, volume = {60}, year = {2016}, yomi = {タカハシ, ヒサミツ} }
