Agriculture in Norman England primarily relied on rain-fed farming, which was sufficient for the region's temperate climate. Crops like wheat, barley, and oats were grown without the need for extensive irrigation infrastructure. Water management efforts in Norman England were concentrated on: Building water mills for grinding grain, which involved controlling rivers and streams. Draining marshes to reclaim farmland, particularly in regions like the Fens. These projects were not irrigation systems as they did not involve transporting water to fields but rather managing existing water resources. [Chibnall 1996], [webpage_Home | Domesday Book] |
