Question

if farmers on the great plains had practiced crop rotation in the late 1800s and early 1900s,
the wheat crop could have
protected against winds.
the dry-farming strategies
would have failed.
the dust bowl would not
have existed.
the soil could have
recovered its nutrients.

Explanation:

Crop rotation is a farming practice that helps maintain soil fertility by alternating crops, which replenishes nutrients. The Dust Bowl was caused by over-farming, drought, and poor soil management. While crop rotation helps soil nutrients, the Dust Bowl's causes were more complex (including drought, wind erosion, and large - scale unsustainable farming). Dry - farming strategies failing isn't directly related to crop rotation. Wheat crops alone don't protect against winds effectively. But crop rotation does help soil recover nutrients. So the correct statement is "the soil could have recovered its nutrients."

Answer:

the soil could have recovered its nutrients.
