The Dust Bowl of North America refers to a catastrophe in the early 1930's when vast areas of the Midwestern and Western farm lands of America became wastelands. This occurred due to a series of dry years which coincided with the extension of agriculture in unsuitable lands. Droughts and dust storms caused by poor tillage practices devastated farms and ranches of the Great Plains; therefore, causing a great exodus of its inhabitants to other, more fertile, lands. The problem had become so great that a nation wide effort was made to resolve the problem. Beginning in 1935, extensive efforts were made by both federal and state governments to develop adequate programs for soil conservation and for the rehabilitation of the dust bowl. Eventually, thanks to government aid, farming became possible again in the Dust Bowl; consequently, farmers have learned many valuable lessons from this dilemma. .
The European settlers who first arrived at the Great Plains found hardy grasslands that held the fine-grained soil in place in spite of the long recurrent droughts and occasional torrential rains. A large number of the travelers settled down in this area and built farms and ranches. These land uses led to soil exposure and great erosion. The cattle ranches were very profitable for the settlers; unfortunately, this led to overgrazing and degradation of the soil. In addition, farmers began to plow the natural grass cover and plant their own crops. Without the original root systems of the grass to anchor the soil, much of it blew away. The wide row crops were very disastrous because between the crops, the land was kept bare; as a result, this area was exposed to the elements. Also, the nutrients in the soil were used up by the plants faster than they could be replaced. The soil had become exhausted. .
The Great Plains are a vast expanse of land located in a region east of the Rocky Mountains in North America.
