|Secretary of Agriculture Henry Wallace is instrumental in overseeing extensive land acquisition and construction at Beltsville. |
46 major buildings and numerous greenhouses are constructed on 12,671 acres.
|Research projects at the Animal Disease Experiment Station in Bethesda, Entomology and Plant Quarantine Station in Takoma Park, and Arlington Farms Experiment Station in Arlington are moved to Beltsville.|
|The Civilian Conservation Corps (CCC) constructs 21 buildings; 79 miles of roads, trails, and bridges; erects 242 miles of fences; lays 126 miles of water, sewage, and drainage pipes; landscapes 500 acres; and moves 78,000 trees and shrubs.|
|Many Government agencies begin as part of USDA and are located at Beltsville: Food and Drug Administration, Environmental Protection Agency, Biological Survey of the Department of the Interior, Forest Service, and Soil Conservation Service.|
|In later years, the National Aeronautics and Space Administration, Office of Naval Research, Department of Commerce, University of Maryland, and Howard University had research projects on USDA land at Beltsville.|
|National Bureau of Standards establishes in 1933 a radio station (WWV) in Building 452 to study radio wave transmissions.|
|In 1935, the Bankhead and Jones Act is passed by Congress. This act results in a change in the research approach of USDA. Significant new funds are available to "conduct research into the laws and principles underlying basic problems in Agriculture in its broadest aspects." |
Because of this Act, many research projects at Beltsville change from a very applied to a more basic approach. These projects received about a 10% increase in funding.
|Significant contributions to landscape and ornamental plant improvement are made. Releases from the 1930's onward include the first dwarf Easter lilies, the first summer blooming dahlias and chrysanthemums.|
|Other releases included cold-hardy crapemyrtles, as well as improved carnations, ornithogalums, amaryllis, viburnums, red maples, elms, magnolias, hollies, pyracanthas, and many other plants. |
Cultivar development continues today as consumer preferences change.
|After demonstrating the role of vitamin A in maintaining sight, researchers determine adults should consume a minimum of 5,000 to 6,000 International Units of vitamin A per day.|
|In response to the need for a smaller, meatier turkey, scientists begin developing a new type of bird. By the late 1940's, the Beltsville small white turkey, which averaged 8-10 pounds with a high percentage of breast meat, begins showing up in stores. |
This turkey line is part of the pedigree of nearly every turkey sold in the U.S. today.
|Vitamin B12, is shown to be essential for egg production and the survival of newly-hatched chicks. This discovery alone increases the hatchability of eggs from 65% to the current 85%, providing an annual savings of 600 million eggs valued at $60 million. |
A vaccine is developed to prevent hog cholera, a disease that costs producers more than $100 million a year. By 1978, hog cholera is eradicated in the U.S.
|The first successful vaccine is produced to immunize cattle against brucellosis, a disease that can also infect humans. |
Phenothiazine, an effective and economical drug for removing many worm parasites from horses, swine, sheep, goats, and poultry, is discovered.
