Founding-Era American Agriculture & Agricultural Technology
Washington, Jefferson, Arthur Young, experimental husbandry, farm maps, crop rotations, threshing machinery, plow geometry, and Atlantic exchange.
Scope
American agriculture in this era was shaped by enlightenment-era experimentation and transatlantic exchange. Washington and Jefferson corresponded with European agriculturalists, designed crop rotations, kept detailed farm diaries, and experimented with plow geometry, manure management, and new crops. This era also encompasses the work of Arthur Young and the British Board of Agriculture, the early development of threshing machines, and the intellectual framework that led to agricultural societies and the first calls for systematic agricultural education. Labor systems—including the central role of enslaved workers—are an inseparable part of this history.
