American farmers in the 20th century tended to over-produce crops compared to the prices the crops could sell for, leading to an effect known as a "cost-price squeeze" where the income received did not meet the cost of production. Farming in the mid-twentieth century was becoming increasingly mechanized, which reduced the cost of labor. However, the
1973 oil crisis increased the cost of fuel, further depressing the net income of farmers. In an attempt to curtail the grain surplus, the US signed the
1973 United States–Soviet Union wheat deal. The period between 1973-1974 saw the prices of crops to double or triple. With low interest rates and rising costs of increasingly profitable agricultural land, many farmers took out loans to purchase more land. As farmers began to increase production, profits again decreased, and farmers frequently borrowed against their land equity to keep operations running. ==Crisis==
