Explanation
Orchards can very well be grown in mountainous soil. These soils are heterogeneous in nature and their character changes with parent rocks, ground-configuration and climate. Consequently, they differ greatly even if they occur in close proximity to one another.
Dustbowl catastrophe is nothing but the dust storm that greatly damaged the ecology of US and Canadian prairies. The main reason for this storm was the wind erosion. Hence to prevent such catastrophes people should be taught well to prevent soil erosion.
Soil conservation is a method of protecting soil from getting eroded either by wind or by water.
