The New York State College of Agriculture and Life Sciences (CALS or Ag School) is a statutory college established and supervised by the State University of New York (SUNY) system. CALS is located on the campus of Cornell University in Ithaca, New York. With enrollment of approximately 3,100 undergraduate and 1,000 graduate students, CALS is the third-largest college of its kind in the United States and the second-largest undergraduate college on the Cornell campus.
Established as a Land-grant college, CALS administrates New York's cooperative extension program jointly with New York State College of Human Ecology. CALS runs the New York State Agricultural Experiment Station in Geneva, New York, and the Cornell University Agricultural Experiment Station, as well as other research facilities in New York.
In 2007-08, CALS total budget (excluding the Geneva Station) is $283 million, with $96 million coming from tuition and $52 million coming from state appropriations. The Geneva Station budget was an additional $25 million.
CALS offers more than 20 majors, each with a focus on Life Sciences, Applied Social Sciences, Environmental Sciences and Agriculture and Food. CALS undergraduate programs lead to a Bachelor of Science degree in one of 23 different majors. The Applied Economics and Management program, for example, was ranked 3rd nationally in BusinessWeek's Best Undergraduate Business Programs, 2012, edition. CALS also offers graduate degrees in various fields of study, including the M.A.T., M.L.A., M.P.S., M.S., and Ph.D..

Cornell's College of Agriculture and Life Sciences is one of the most renowned institutions in its field. In 2019, it is ranked 1st in the "Food and Nutrition"  and "Agricultural Sciences"  sectors of Niche.com
With an admission rate of 11.5% for the fall of 2018, admission into the college is extremely competitive and in the middle relative to the other colleges at Cornell. 
The Agriculture Quadrangle (Ag Quad) is a grouping of buildings dedicated to programs offered by the NYS College of Agriculture and Life Sciences. The oldest building on the quad is Caldwell Hall (1913). The Plant Science Building (1931), and Warren Hall (1931), flank the art deco style Albert R. Mann Library (1952). A newer Kennedy and Roberts Halls replaced the original 1906 building, and The Computing and Communications Center (1912) was formerly Comstock Hall). These buildings are owned by New York State, which pays for their construction and maintenance.
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  (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  and also substations: the Vineyard Research Laboratory in Fredonia, Hudson Valley Laboratory in Highland, and Long Island Horticultural Research Laboratory in Riverhead.
The Social Media Lab, is part of the College's Communications Department. 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. Studies examine human behavior, personal experience, and human interaction in the digital realm along the dimensions of language processes, perception, self-representation, and interpersonal interaction. 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!" These statements buffer the otherwise negative experience of social rejection or ostracism.
The recently established Rich's Food Safety Lab was made possible by a donation from frozen food industry giant Rich. The laboratory aims to engages in critical food safety research and the education of the next generation of food safety leaders.
Cornell's first president, Andrew Dickson White, had little enthusiasm for agricultural education, and the Board of Trustees were likewise without much enthusiasm. Agriculture could not be ignored, however, because Ezra Cornell was deeply committed, and the provisions of the Morrill Land Grant Act required it. After much difficulty, George Chapman Caldwell was recruited in 1867 as Professor of Chemistry (Agricultural Chemistry). He was the very first professor of what was to become the Cornell University.
The university opened in September 1868 with professor Caldwell, the nominal leader of a group of three professors with interests touching upon agriculture. In addition to Caldwell, there was Albert N. Prentiss, professor of botany (with some reference to crops), and Dr. James Law, professor of veterinary medicine. The Faculty of Agriculture consisted of this informal group of three and a professor of agriculture of the moment.
The arrival of Isaac P. Roberts, as professor of agriculture, from Michigan, in 1874, finally brought credibility to agriculture at Cornell. During the period of 1879-1887, Cornell president Charles Kendall Adams gradually changed the Trustees seemingly hostility toward agriculture. In June 1888, the "informal" departments, including agriculture taught by Isaac Roberts, agricultural chemistry taught by George Caldwell, botany taught by Albert Prentiss, entomology taught by Henry Comstock, and veterinary medicine taught by James Law, were combined to form the Cornell College of Agriculture.
Also in June 1888, horticulture, which had played a minor role in botany until it was discontinued by the trustees in 1880, was reestablished as an independent department in the college, upon the recruitment of Liberty Hyde Bailey as professor and department head. Roberts was appointed Director of the college and dean of its faculty while retaining his role as professor of agriculture and heading a department of agriculture within the college of the same name.
Legislation establishing the New York State College of Agriculture at Cornell passed the state legislature and was signed by the governor in May 1904. The legislation passed in spite of ?violent? opposition and intense lobbying led by Chancellor James Roscoe Day of Syracuse University acting for Syracuse and six other universities and colleges in New York.
Established in 1874 as the Department of Agriculture, the department became a college in 1888. In 1904, eminent botanist and horticulturist Liberty Hyde Bailey, along with New York State farmers, convinced the New York Legislature to financially support the agriculture college at Cornell, a private university that had been established in 1865 as New York's land-grant institution. Thus, it became a statutory college, and changed its name from the New York State College of Agriculture in 1904 to the New York State College of Agriculture and Life Sciences in 1971.
In 1898, the State Legislature established a separate New York State College of Forestry at Cornell. However, the school ran into political controversy, and the Governor vetoed its annual appropriation in 1903. In 1910, Liberty Hyde Bailey, the Dean of Cornell's Agriculture College, succeeded in having what remained of the Forestry College transferred to his school. At his request, in 1911, the legislature appropriated $100,000 to construct a building to house the new Forestry Department on the Cornell campus, which Cornell later named Fernow Hall. That Forestry Department continues today as the Department of Natural Resources. In 1927, Cornell established a 1,639-acre (6.63 km2) research forest south of Ithaca, the Arnot Woods.
In 1900, the college began offering a reading course for farm women. In 1907, the Department of Home Economics was created within college. In 1919, the Department of Home Economics became a school within the Agriculture College. Finally, in 1925, the Home Economics department became a separate college, although both colleges continued to work together to provide cooperative extension services.
The World Food Prize has been awarded[by whom?][when?] for the sixth time to a Cornellian. Dr. Andrew Colin McClung, M.S. 1949, was awarded the World Food Prize for helping to transform a large area of Brazil into fertile land. His recommendations regarding key agricultural inputs made this transformation possible.
