The dust bowl was the result of a series of dryers drought in the 1930s Where millions of pounds of topsoil were desiccated and
blown from the great plains in deposited hundreds of miles away what most likely contributed to the loss of fertile soil during the dust bowl in the years that immediately followed that event? A. Contour plowing
B. Absence of native grasses
C. Perennial crop ground over
D. No till agricultural practices
The grasses, which acted as a windbreak and whose roots anchored the soil in place, were overgrazed and/or removed to allow for farming. Once a few years of severe drought affected the area, any wind storm was able to blow the topsoil away, rendering the farm land of the Great Plains virtually unusable in many areas. Ground cover is an essential part of sustainable agriculture.
