One reason was that there was just not enough rainfall to sustain the crops. John Wesley Powell says that it is necessary to have 20 inches of annual rainfall in the Southern Great Plains to support farming. Sadly, the average annual rainfall was 17 inches. The Southern Great Plains could not support farming. Therefore, the crops died and more dust storms came (Doc. E). Fred Folkers was barely staying afloat with his horse-drawn plow. The tractor changed everything for him. A tractor could do the work of ten horses! The tractor reduced the time needed to farm an acre of wheat. This meant that he could farm larger farms and grow more wheat. However, it meant that there was a greater loss of short grass. Folkers may have been a great businessman with the efficient machines, but he was destroying the short grass that held the soil in place (Doc. C). Our lives are dependent on grass. Grass is what feeds the cattle that feed us. The short grass prairie covers the soil and holds it in place. It absorbs rainwater and prevents erosion. When farmers plow the fields and don’t get enough rainfall, their crops die. Soon the dry soil with turn into dust and create the dust storms (Doc.
