Why did farmers let some fields lie fallow?

Question

Options:
To reduce the surplus of crops
To bring new land under cultivation
To increase the souls productivity
To allow serfs to grow their own food

Answer 1

All of the options mentioned could be reasons why farmers let some fields lie fallow, but the most accurate answer is "To increase the soil's productivity." Letting fields lie fallow for a period of time allows the soil to replenish its nutrients, retain moisture, and recover from the depletion caused by continuous cropping. This practice helps maintain the fertility and long-term productivity of the soil.
