Why did farmers let some fields lie fallow?

Answer 1

Farmers would let some fields lie fallow to allow the land to rest and recover from constant planting and harvesting. This was done to maintain and replenish the nutrient content of the soil, which gradually depletes over time due to repeated cultivation. Fallowing also helps reduce soil erosion and pest infestation. By rotating crops and letting some fields go fallow, farmers could maintain the productivity of their land and ensure that it remained fertile for future generations.
