PREFACE 



In the preparation of this report, four considerations were kept in 

 mind: (1) How are agriculture and forestry adversely affected by wastes? 

 (2) What wastes are contributed by agriculture and forestry? (3) How 

 has research in the U.S. Department of Agriculture and the State agri- 

 cultural experiment stations contributed to the amelioration of waste 

 problems? (4) What problems in waste production and management 

 continue to need attention by agriculture and forestry? Commentary on 

 these four considerations comprises the corresponding four appendices to 

 the report per se. 



The advice and helpfulness received from the many, many people in 

 the U.S. Department of Agriculture and the State agricultural experiment 

 stations during the compilation of this report are deeply appreciated. 

 The compiler accepts full responsibility for all errors of omission and 

 commission found herein.
