The Connecticut Agricultural Experiment Station (CAES) is the Connecticut state government's agricultural experiment station, a state government component that engages in scientific research and public outreach in agriculture and related fields. It is the oldest state experiment station in the United States, having been founded in 1875. Its official mission is to "develop, advance, and disseminate scientific knowledge, improve agricultural productivity and environmental quality, protect plants, and enhance human health and well-being through research for the benefit of Connecticut residents and the nation." The station operates a main research campus in New Haven, a research farm in Hamden, a satellite research facility and farm in Windsor, and a research farm in Griswold. The Storrs Agricultural Experiment Station is a separate agricultural research agency, founded in 1887 and part of the University of Connecticut, which also receives state and federal funding. Historic campus in New Haven The experiment station's main facility in the Prospect Hill area of New Haven dates from 1882 when it became the permanent home of the first state agricultural experiment station. The station had been founded at Wesleyan University in 1875 and moved to Yale in 1877 as it became associated with the Sheffield Scientific School. By 1882, the station needed more space, and Sheffield needed its space back. A property at the top of Prospect Hill was purchased and buildings built, using a $25,000 appropriation from the state legislature. The buildings include the Osborne Library, built in 1882-83 and believed to be the oldest building at any state agricultural experimental station, and the Johnson Laboratory, which has notably large brackets supporting its wide overhanging eaves. The station was declared a National Historic Landmark in 1964, recognizing its significance as the first state agricultural station in the nation. For much of its history, the Connecticut Agricultural Experiment Station worked closely with the Storrs Agricultural Experiment Station, which was founded in 1887 at the University of Connecticut in Storrs. The main campus in New Haven currently houses the activities of six departments: Analytical Chemistry, Biochemistry and Genetics, Entomology, Environmental Sciences, Forestry and Horticulture and Plant Pathology and Ecology. Recent research activities Analytical Chemistry The founding department of the Station, Analytical Chemistry began its work in 1875 testing fertilizer and later seeds, animal feed, human foods, drugs, and pesticides. This work continues today, and is organized into two categories: food safety and environmental monitoring. The department works with State
