Excerpt from the report Preface: This Agriculture Information Bulletin (AIB) provides a general overview of agricultural research activities in the area of energy as it relates to farming and ranching. It is an awareness document that tells generally what is being done and what has been accomplished largely during the 1970's in significant areas of agricultural research funded wholly or partially by the U.S. Department of Agriculture (USDA) and State governments, unless otherwise stated. It is written for agricultural leaders, practitioners, farmers, and ranchers—all who advise about farming or who actually till the soil.
