Thanks to all who responded on the ante-bellum agricultural study question. That has certainly given me a good start on getting into useful literature. Moving forward a bit, are there studies of post-Civil War and 20th century agricultural productivity figures that have useful stats over the years to show the rise of the mechanical era in agriculture? I have seen some by Googling but there are large gaps. For instance, now one farmer with seasonal help can manage 2000 acres of crops. I have figures for somewhere in the 1930's but would like to be able to graph the increases over time and then use the rural/urban X graph to show the decrease in agricultural manual laborer needs. What would be really interesting is to see how productivity fared after the Civil War until the rise of self-propelled machinery in the early 20th century. Thanks in advance.
