Better Grain-Sorghum Crops

Description: "This paper presents the best-known methods of improving the grain-sorghum crops on the farms where they are grown. These methods are simple and inexpensive of time or money, and are therefore within the reach of all farmers. More attention to the bettering of the quality and yields will be repaid as fully in these crops as in other cereals." -- p. 2. Sorghum crops can be improved for drought resistance, earliness, stature, productivity, and adaptability to machine techniques.

Growing Winter Wheat on the Great Plains

Description: "This bulletin is intended to answer the requests for information on the production of winter wheat on the Great Plains under dry-farming conditions that arise from the stimulus of a present and prospective price much higher than that under which the agriculture of the section has been developed and from the campaign for a large increase in the crop to meet the necessities of war conditions." -- p. 3. Topics discussed include wheat varieties and seeding.

Preventing Soil Blowing on the Southern Great Plains

Description: "Soil blowing is often a serious problem from December to May [in the Southern Great Plains], when the soil is, in many cases, bare and winds are high. This period is often referred to as the 'blow season.' The whole art of preventing and controlling soil blowing consists in keeping nonblowing materials on the surface. These may be crops, crop residues, or clods. When crops are absent, the essential feature in preventing soil blowing is the use of implements that lift clods and other nonblowing… more

Strawberry Culture: Western United States

Description: "This bulletin applies to that part of the United States in which ordinary farm crops are grown largely under irrigation. It describes methods practiced in the more important commercial strawberry-growing districts in the irrigated regions of the West; it aims to aid those familiar only with local and perhaps unsatisfactory methods, as well as inexperienced prospective growers. The fundamental principles of the irrigation of strawberries are substantially the same as those which apply in the gr… more

Strawberry Culture: Western United States

Description: Revised edition. "Strawberries can be grown in those parts of the western Untied States in which ordinary farm crops are irrigated as well as in western Oregon and Washington, where irrigation is not essential but may be profitable. The principles of irrigating strawberries are essentially the same as those for other crops. Because strawberries are sensitive to the alkali salts that irrigation brings to the surface, such salts must be washed out or skimmed off. The strawberry grower, after choo… more

Tabulation or Ore Reserves and Past Production for the Uranium-Vanadium Region of Colorado, Utah, New Mexico, and Arizona

Description: The tabulations on these pages include all of the known areas in Colorado, Utah, New Mexico, and Arizona having economically important uranium-vanadium deposits of the type which are generally referred to by the terms roscoe-lite and/or carnotite. Though similar deposits are known to exist in other areas they are to be viewed as being little more than mineralogical curiosities.
