The second part of the blog series looks at the historical Iowa corn planted area from 1926 to 2015. Iowa is one of the most important corn producing states in the US. Hence it is important to understand the historical corn trends in Iowa if we want to make future predictions

The bubble chart shows two very significant trends in the corn planting history of Iowa:

1. southern Iowa districts have a reduced share relative to the other states
2. northeast Iowa district share has increased significantly

This is the overall US trend witnessed in part 1 of this blog series. Given this history should we expect that corn planting in Iowa will shift further northeast? The data seems to suggest we should.

The data comes from USDA/NASS again.
