What agricultural system involved rotating fields to maintain soil fertility across seasons?

• A. The two-field system
• B. The four-field system
• C. The single-field system
• D. The three-field system

Answer: (D)

Rotating fields to keep soil fertile is about crop rotation and giving the land a rest. In the three-field system, the farm is divided into three fields. Each year two fields are planted with crops and the third is left fallow. By moving which field is fallow each season, the soil has time to recover its nutrients and regain structure, which helps maintain productive yields over time. This approach specifically implements a three-field cycle to balance cultivation with soil conservation. Two-field and single-field setups use less balanced rotation and tend to wear soil more quickly, while the four-field system is a later refinement that adds more plots and crops to sustain fertility even further, often without a long fallow period.
