18. Which farming technique most contributed to the Dust Bowl?
Answer: C
Dry-land farming most contributed to the Dust Bowl.
Dry-land farming practices were central to the agricultural methods employed during this period, leading to the severe soil erosion and degradation that characterized the Dust Bowl. This technique, which involved the cultivation of crops in regions with limited moisture, failed to account for the environmental conditions, ultimately exacerbating the drought's effects.
A) Crop rotation
Crop rotation involves alternating the types of crops grown in a specific area to maintain soil fertility and prevent erosion. While beneficial for sustainable farming, crop rotation was not a primary factor in the Dust Bowl; in fact, it could have mitigated some of the soil degradation linked to over-farming.
B) Terrace farming
Terrace farming is a method that involves creating stepped levels on sloped land to reduce soil erosion and manage water runoff. This technique was not widely used in the areas affected by the Dust Bowl and, therefore, did not contribute significantly to the environmental disaster.
C) Dry-land farming
Dry-land farming practices, which emphasize the cultivation of crops with minimal moisture, played a significant role in the Dust Bowl. These methods led to the over-extraction of soil nutrients and increased vulnerability to erosion, which was exacerbated by prolonged drought conditions.
D) Shallow-lakebed farming
Shallow-lakebed farming refers to agricultural practices in areas that were once covered by shallow lakes. This method is not directly related to the Dust Bowl's causes, as it did not contribute to the widespread soil depletion and erosion that characterized the event.
Conclusion
The choice of dry-land farming as a predominant technique during a time of drought ultimately led to the catastrophic conditions of the Dust Bowl, as it did not support the soil's health. In contrast, the other options—crop rotation, terrace farming, and shallow-lakebed farming—either provided sustainable practices or were not utilized in the affected regions, reinforcing why dry-land farming is the correct answer.
