Question 4 • United States History and Geography

If farmers on the Great Plains had practiced crop rotation in the late 1800s and early 1900s,

Answer
A
the soil could have recovered its nutrients.
B
the Dust Bowl would not have existed.
C
the wheat crop could have protected against winds.
D
the dry-farming strategies would have failed.

Explanation

Crop rotation means planting different crops in the same field over time. Different crops use and restore different nutrients, helping the soil recover fertility instead of being depleted by repeatedly growing wheat. So the soil could have recovered its nutrients; crop rotation would not by itself guarantee that the Dust Bowl never occurred.
