Résumé :
|
Here is a concise presentation of the fundamental nature and cause of soil erosion,the aims of soil conservation,and the principles and methods of saving the soil and maintaining its productivity.The authors treat soil conservation as a problem of humanity.The emphasis throughout is on the fundamental principles of soil erosion and soil conservation in order to show how the various conservation methods fit together and how they can be applied on the farm.The authors offer no "recipes" for soil management.Instead they provide a basic picture to help the reader understand the soil and what happens to it under various forms of land use so that he himself can work out the solution to any soil-conservation problem on the basis of the principles.Since much of the knowledge necessary for an understanding of the principles of soil erosion and of the conservation methods is presented in the book,it is a self-contained text.While the authors have based their statements on a number of different sources,they have succeeded in presenting a unified picture of the subject.This book will be of interest to everyone concerned with land use problems,especially farm management specialists,country agents,and soil conservation personnel.
