[13] The Plant Science Building (1931), and Warren Hall (1931), flank the art deco style Albert R. Mann Library (1952).

The college operates extension programs through the New York State Agricultural Experiment Station (NYSAES) in Geneva, New York, in 20 buildings, including the Barton Laboratory Greenhouse and Sutton Road Solar Farm[15] (a 2-megawatt energy facility that offsets nearly 40 percent of NYSAES annual electricity demands), on 130 acres (0.5 km2) and over 700 acres (2.8 km2) of test plots and other land parcels used to conduct horticultural research[16] and also substations: the Vineyard Research Laboratory in Fredonia, Hudson Valley Laboratory in Highland, and Long Island Horticultural Research Laboratory in Riverhead.

In this modern research laboratory, faculty supervise undergraduate and graduate research focusing on human interaction in CMC and online communities, including the investigation of social phenomena, such as disclosure or deception among users of social media computer applications, such as Facebook, Grindr.

In 2009, The Social Media Lab coined the term, the Butler Lie, a reference to factually untrue verbal communication used to politely initiate or end an instant message conversation, such as "Gotta go, boss is coming!"

Agriculture could not be ignored, however, because Ezra Cornell was deeply committed, and the provisions of the Morrill Land Grant Act required it.

[20] During the period of 1879–1887, Cornell president Charles Kendall Adams gradually changed the Trustees seemingly hostility toward agriculture.

The college made discoveries and disseminated results from other schools, especially regarding insect control, fertilizers, breeding, veterinary medicine, cultivation, and farm management.

[23] The three buildings were determined in 1973 to be decrepit, and despite being listed on the U.S. National Register of Historic Places in 1984, Cornell had them demolished in 1988.

However, the school ran into political controversy, and the Governor vetoed its annual appropriation in 1903.

In 1927, Cornell established a 1,639-acre (6.63 km2) research forest south of Ithaca, the Arnot Woods.

[citation needed] In 1919, the Department of Home Economics became a school within the Agriculture College.
