Field of Dreams
A field rotation system was a schedule for planting different crops so the same crop would not grow in the same field year after year. The early system used in the Middle Ages was the two field system, in which the field was tilled for a crop one year and allowed to recover the next. Later, the three field system was used, in which a field was tilled for one crop one year, tilled for a different crop the next year, and allowed to lie fallow to recover in the third. Fallow fields were used for grazing.
