This past month, the UC Merced Library made 2,898 digitized items from the UC Cooperative Extension, Fresno County archive available online. It is our newest collection made publicly available as part of the UC Cooperative Extension Archive and CARA project. The collection represents extension work in Fresno County over the twentieth century and provides a fascinating angle on agriculture in the Valley. Many of the items are from the files of farm advisors and the historical records they inherited from their predecessors. Reports reveal the cumulative results of crop trials that, for example, examined the effects of fungicides and growth regulators. There are newsletters such as Forage Queen, Tree TopicsIn-a-Nutshell and other communication materials that imparted information to growers and families in the Valley. There is also a substantial amount of material related to the 4-H youth development program and CalFresh,a statewide program that provides food benefits to low-income families and individuals. These documents demonstrate Cooperative Extension’s reach throughout the community.

Visit Calisphere to see the entire digitized archive: Topics include growing and harvesting of almonds, pistachios, grapes, alfalfa, and cotton among other crops. Other sets of records are categorized by processes such as irrigation, fumigation, soil formation, and fertilization.
