The Landscape of Capitalism by former University of Iowa professor Robert F. Sayre (1933-2014) is an excellent short history of Iowa agriculture. I read Sayre’s essay many years ago and had all but forgotten it, but it was restored to my memory recently by a conversation I had with an ag drainage engineer.
