OSALT was founded in 1995 by Will Newman and Sue Clark as a 501(c)3 non-profit land trust. Its mission is to hold agricultural land in perpetuity for the purposes of research and education on sustainable agriculture. OSALT now holds seven pieces of land in trust. Some are farms outside the city; some are community gardens in the city. OSALT also runs several programs with aligned missions, the largest of which is the Urban Farm Collective.
