The answer is "sodbusters."

Explanation:

The answer is related to the history of the "Great Plains."

The Great Plains was located in the middle of the United States territory. The land in this area was very dry and flat that it was hard to farm. This was the reason why people didn't want to live in this place. This occurred in the 1800s. The area became idled and bad for the economy.

However, the government thought of a strategy to attract people into the area. They started selling small lands for a cheaper price. They also promised that anyone who could farm the land in five years, will have the chance to completely own it for themselves. Of course, this attracted many people. Some of the settlers came from Europe and the East.

When the settlers came, they started to farm but this gave them lots of hardship because the soil was stuck with the grass growing on it. This is the reason why the farmers who attempted to farm the Great Plains were called "sodbusters."

Production of crops was unsteady on the Great Plains because most of the time, the weather was hot and dry. It was very common to have drought.
