Agricultural Maps

Oranges - All.pngIn the 1920s, growers and food processors needed more information about what crops were being grown, how many acres or orchards of each crop existed, how many were planned, and how much each acre produced.  Why?  Because they wanted to make the process of growing and processing produce more predictable.  The idea was, that if canners and growers knew how many acres of each crop existed they could plan better for the future. 

The California department of agriculture began keeping detailed official records and publishing them in the California Fruit and Nut report.  These maps came from the consolidated 1905-1951 California Fruit and Nut report.  They show where and about how many acres of crops were being grown in California.  

These maps show a lot of information.  But, what is missing?  A historian's first response would probably be...time.  These maps are static, meaning they do not show the change in crop size or location over time.  Despite that, historians still use these maps to get an idea of the crops grow in California and can compare them to each other to show the relationships between crops grown in the state.
