About The Book

Soil conservation is one of the important agricultural sciences. There is great need for more real soil conservation teaching As soil conservation interest and action have developed progressively from year to year, demands for pertinent information in the form of suitable teaching material have mounted correspondingly. The author has compiled a great store of factual information about land resources, the problem of erosion, and the methods of soil and water conservation. This volume undertakes to brief for the student the more important aspects of the serious problem of soil and water wastage and of the more outstanding methods of soil and water conservation.
