South Carolina Regional Study

Recently I have been studying a lot about the different regions of South Carolina. Farmers are very limited to what they can grow due to the type of soil and other conditions that are controlled by their locations. I have learned that our state varies widely in terms of topography and other geographical conditions, which makes for an interesting array of farmers across the state.
Here are some interesting maps that display the regions of South Carolina.

Here are some significant marked areas in each region that influence agriculture in that area economically and geographically.
