How did land speculators and their agents convince people that the southern Plains were changing and could sustain farming as well as livestock grazing?

Land speculators and their agents used advertising and promotional campaigns to portray the southern Plains as fertile land suitable for farming and grazing. They often exaggerated the potential of the land, highlighting successful farming and ranching operations as examples. Additionally, they offered incentives such as low-priced land and easy credit terms to attract settlers to the region.
