Dust Bowl

Dust Bowl was a term born in the hard times of the people who lived in drought-stricken region during the great depression. Dust Bowl or the Dirty Thirties was a period of severe dust storms causing major ecological and agricultural damage to America and Canadian prairelands from 1930 to 1936. This phenomenon was caused by severe drought coupled with decades of extensive farming without crop rotation, fallow fields, cover crops or other techniques to prevent erosion.
The most visible evidence of how dry years of the 1930s was the dust storm. Tons of windblown soil barren fields and carried in storm clouds for hundreds of miles. Technically, the driest Plains-southeastern Colorado, southwestern Kansas and the panhandles of Oklahoma and Texas known as the Dust Bowl, and many dust storms started there. But the entire region and finnaly the entire country is affected.
Millions of hectares of farmland became useless, and hundreds of thousands of people were forced to leave their homes, many of these families traveled to California and other states, where they found the economic conditions slightly better than the previous. Owning no land, many traveled from farm to farm picking fruit and other crops at starvation wages.
The Dust Bowl taught farmers new farming methods and techniques. The 1930’s to help whole new era of soil conservation. Perhaps the most valuable lessons learned from the Dust Bowl-care land. The Dust Bowl's future is Almost exclusively controlled by the weather. The prolonged drought combined with the Meteorological phenomena of the 1930's was rare and never before Tortured the Great Plains as it did. Droughts and Winds still cause many problems, but most are averted and minimized with proper soil conservation. When times turn dry again, will from the wind blow and history repeat Itself? Only time will of tell.
