"This bulletin deals with the dry-farming methods practiced on grain farms in the Pacific Northwest, where the rainfall is less than 15 to 18 inches annually, but it also contains advice helpful to all farmers of that region who practice summer fallowing. Its purpose is to show the possibility of increasing crop yields in the dry-farming areas by using improved methods and to discuss the practices which have been found most advantageous. ...The highest yields have been secured by plowing in the early spring and giving enough cultivation after plowing to keep the weeds well under control. The purposes of summer fallowing and details of the methods by which it is accomplished are given, and the application of these methods to the cultivation of "blow" soils and "nonblow" soils. Methods are suggested for preventing and stopping the blowing of soils. Attention is given to the saving of man labor by the use of large power units, methods of seeding winter and spring wheat are outlined, and suggestions are made for maintaining the organic matter in the soil." -- p. ii
