I can only tell you what he told me. Central Indiana to Northern Kentucky was aparently much less effected. I never knew them to grow wheat, the grain in that area is almost always corn. Unlike the agriculture we know today, he used mostly draft animals to plow with until my Mother was born in the early 40's. He told me about standing on a horses back to watch my Grandmother walk to the barn to milk the cows. As far as the price dropping below market price as I said they lived a pretty self sustaining lifestyle with little cash changing hands. I'm sure extra grain turned in to extra cattle and milk if there wasn't a market for it. They kept a "Garden" most of us would call a small farm up until they retired. He spent his life working and worked until he was 90 in his shop making toys and furniture.
