How did many farmers get into debt in the 1920s? Explain how world war 1 and crops prices affected farmers during this time period?

World War I put crops in high demand, so farmers increased harvest yields, and had to buy more expensive equipment and land. After the war, demand dropped sharply, but production stayed high because of the new equipment and farming methods. In effect, farmers were unable to sell their massive surpluses and unable to pay their debt.
