"The United States Department of Agriculture, since 1908 at the Belle Fourche Field Station, near Newell, and since 1912 at the Ardmore Field Station, has been conducting thorough investigations of methods of crop production in South Dakota. The results of these investigations show that the high fluctuation of yields, due to fluctuating rainfall, can not be sufficiently overcome by cultural methods to change the problem materially. These results and the experience of farmers who have succeeded indicate that the most favorable conditions for grain production are found when combined with or subordinated to stock production. The system and methods recommended are 1) keeping live stock to the capacity of summer pasture and winter feed, 2) the growth of cultivated annual crops (corn and sorghum) for winter feed, and 3) the growth of small grains following the corn without plowing. This system may be modified as local or individual conditions warrant the growth of alfalfa for hay or seed, or the growth of a larger acreage of wheat or other grains." -- p. 2
