註釋This book is designed for individuals who want to apply conservation practices either without or with minimal technical assistance. These individuals include students who want to practice soil/water conservation with some instructor guidance and others who want to apply the principles in their own way, to their own conditions, and within their own capability to apply them. To meet these needs, the book includes a discussion and description of soil/water conservation methods for the small operator, at the same time recognizing changes brought about through improved technology and by larger and more complex farm equipment. It is intended to be useful for the small acreage owner and for urban dwellers who have a soil/water conservation problem. Practices discussed can also help school officials select a school site and develop a conservation plan on the area-a plan that can be used to teach wise use of soil/water and related resources, and to serve as an outdoor classroom. The book is divided into 20 chapters and includes an appendix summarizing approved soil conservation practices (related to each chapter), an index, and glossary. Among the topics presented are conservation tillage, contour farming, strip crop farming, preventing and healing gullies, and controlling sandblows. (JN)
