متن يادداشت
This book describes concepts, value judgments and background information on the expanding conservation tillage practices in the United States and provides a technical appraisal of the state of the art. Still, much remains to be learned about the agronomic, agricultural engineering and environmental parameters; and it is hoped that the inormation herein presented will stimulate further research toward a more integrated apporach to conversation tillage practices.
