Question

What method allowed soil to recover from cash crop production but was impossible for poor farmers

Answer 1

Leaving fields unplanted allowed soil to recover from cash crops production, but it was impossible for poor farmers who needed the money from the sale of their crops

Answer 2

Leaving the fields unplanted

Step-by-step explanation:

It is said that the soil can recover from cash crop productions if you leave it unplanted for a while. It was not possible, though, to the small farmers. Since they needed the money to survive, the small farmer did not have the luxury to wait for long periods. Since they needed to keep selling crops to survive, they didn't really have the time to let soil recover.
