Crop rotation and basic land management techniques stop farms from becoming rapidly exhausted. By changing field usage every year and allowing land to lie fallow or be used as pasture, the goodness of the land is slowly restored. Crop yields and surpluses improve as a result, and the increased output adds to population growth. Slave labour also helps, as peasant farmers generally keep more produce for themselves.

This kind of farming can be upgraded as the settlement grows.
