The U.S. Department of Agriculture's (USDA) agricultural engineering research began in the Division of Irrigation Investigations in the Office of Experiment Stations in 1898. By 1915, the Division of Agricultural Engineering was created within the Office of Public Roads and Rural Engineering, Bureau of Plant Industry. Agricultural engineering attained bureau status in 1931, and included the Divisions of Irrigation, Drainage and Soil Erosion Control, Mechanical Equipment, Structures, and Plans and Services. In 1939, the Bureau of Agricultural Chemistry and Engineering was created, followed in 1943 by the establishment of the Bureau of Plant Industry, Soils, and Agricultural Engineering. The USDA reorganized in 1953, and the new Agricultural Engineering Research Branch became part of the Agricultural Research Service. In 1957, the branch became its own division with four branches, including Crop Production, Livestock Engineering and Farm Structures, Harvesting and Farm Processing, and Farm Electrification.
