John A Widtsoe
Dry-Farming-A System of Agriculture for Countries under a Low Rainfall is a classic agriculture technology text by John A. Widtsoe. The book now offered is the first attempt to assemble and organize the known facts of science in their relation to the production of plants, without irrigation, in regions of limited rainfall. The needs of the actual farmer, who must understand the principles before his practices can be wholly satisfactory, have been kept in view primarily; but it is hoped that the enlarging group of dry-farm investigators will also be helped by this presentation of the principles of dry-farming.
