That's an interesting view, but it is not one that I think is reflected in most sources.For sure, there are, I wasn't trying to imply that every part of every one of these states is less ideal. Of course there is local variability. But speaking in broader generalities, many of the planes states which were first populated for farming in the 1930's, are inferior growing locations compared to the places those people left behind back east. The migration happened for reasons tied to land cost and government assistance, and not because it was better land or climate.
First off, it is the Plains states, as in the Great Plains, where the prairie grasses grew taller than a person on horseback in many places. The soil under those grasses built up over tens of thousands of years from glacial dust (loess) and grass fires, making the soil rather rich on a global and US scale.
Water is a limitation in some areas for some crops, as is growing season, and soil minerals. Farmers are astute business folks (and custodians of their lands) for the most part, and do try to optimize returns (harvest yield and sales prices) against input costs. That's why sunflowers get grown in North Dakota, and not in say southern Missouri.
I don't think that your 1930s comment aligns with known settlement patterns. What did change in the 1930s was the economic and social impacts of the Great Depression that cost many small farmers their farms and started the growth in farm size, abetted by an increasing mechanization of agriculture.
