In the early 1930s, why did so many farmers lose their land?

The correct answer is:  

They could not earn enough from farming to pay their mortgages.

During the Great Depression, farm foreclosures became a rising problem. Within 1929 and 1933, the third part of American farmers lost their farms. They were in deep debt, some holding a mortgage and others requiring credit to maintain production. The declining crop prices made it imposible for them to pay off their mortgage loans.
