Planting season is in full swing, although things are done a bit differently than they were when this photo was taken (for which I think most farmers are grateful). Whether this Cooperative Extension Service photo is post-harvest or pre-planting, I’m not sure, but either way, technology has clearly advanced and farmers use tractors rather than horses for their plowing and tilling. This May marks the 100th anniversary of the Smith-Lever Act, which established cooperative extension services throughout the United States. In Iowa, an early form of Extension had already existed for about 10 years when the federal act came to be in 1914. This and other Extension-related photos can be found on our Flickr site. For more information on Extension and its history, see these collections and, of course, the Iowa State University Extension and Outreach website. Also of interest may be College of Agriculture and Life Sciences collections, and any of our agriculture-related manuscript collections. Come in and see us!
