 Development continued after the introduction of the automobile, but it was not until after World War II that intensive development came to the Beltsville area.As the federal government grew, in 1910 the U.S. Department of Agriculture (USDA) began to purchase land in Beltsville for its Agricultural Research Service, the main in-house research arm of the USDA.The land now houses the Henry A. Wallace Beltsville Agricultural Research Center (BARC).
