The Agricultural Revolution is the name given to the drastic changes in the farming process that occurred in the 1600's onwards. The spread-out, shared farms, common under the "open-field system" of cultivation, turned into more compact, but larger, farms. The many problems associated with open fields; the overgrazing of animals, difficulty in reaching consensus for change, and single herds that had led to a spread of animal diseases and uncontrollable breeding breeding; had all become generally solved (Gernhard). Farmers had discovered a crop rotation system that allowed them to forgo leaving up to half the land unused or fallow between each planting.
