About this book

Dry-Farming is presented as a system of agriculture for countries under low rainfall, by John A. Widtsoe. The preface says nearly six tenths of the earth's land surface receive an annual rainfall of less than twenty inches, and can be reclaimed for agricultural purposes only by irrigation and dry-farming.

The text works an example in which the production of one bushel of wheat will require 60 times 750, or 45,000 pounds of water. The text says that with 10 inches of rainfall, which up to the present seems to be the lower limit of successful dry-farming, there is a maximum possibility of producing 25 bushels of wheat annually. The text says water is the essential consideration in dry-farming, else there would be no dry-farming. Chapter XI, Sowing and Harvesting, says that though proper dry-farming insures a first-class seed-bed, the problem of sowing is one of the most difficult in the successful production of crops without irrigation. The text says wheat is king in dry-farming, corn a close second.
