A graphic summary of American agriculture based largely on the census
1931
Baker, O. E. (Oliver Edwin)
The decade since the World War has been in many ways the most extraordinary period in American agriculture. For the first time in the Nation's history, the census of 1925 showed a decrease (since 1920) in crop acreage, in farm animals, in number of farms, and in farm population. Nevertheless, agricultural production increased more rapidly from 1922 to 1926, inclusive, than in any period since 1900, and probably since 1890, when the agricultural occupation of the prairies approached completion.
