"In the nation's effort to produce adequate quantities of all agricultural products to meet the war needs of the United Nations, conservation assumes added importance. Advancements in the management of croplands to conserve soil and moisture, which have come about in recent years as a result of experimentation and the experiences of many farmers, show that conservation increases crop yields. Strip cropping is one of the conservation practices. In its various forms and patterns, it is applicable to a large area of the United States. With the farmer rests the major responsibility of obtaining conservation on the land. Each farmer should examine for himself the need of strip cropping his cultivated land and in doing so should find the information contained in this bulletin helpful. The kinds of strip cropping, the factors influencing their use, methods of application, value in conserving soil and moisture, and the adaptation of strip cropping to the northeastern and north-central, the southeastern and western Gulf, the Great Plains, and the far Western States are discussed." -- p. ii
