People plowing up too many fields at once, and not using crop rotation.
That is what mostly caused the Dust Bowl not the drought so much. Farmers were plowing up a lot of the grasslands (in places like kansas and
nebraska) combined with dry and hot weather the open soil from the plowed fields dried out and was swept up like a sand storm in Egypt.
That's one reason why farmers don't grow a crop on the same field two years in a row, combined with other reasons such as preventing mineral
depletion and disease.
