Question

Why did farmers let some fields lie fallow​

Answer 1

Answer:

This is because the same type of crop planted repeatedly in the same area keeps draining the land of the same nutrients needed for that plant's growth. ... In the past, not planting anything (also called leaving the field fallow) allowed the land to rest and replenish its nutrients.
