OFRF Networks - The Organic Agriculture Consortium

The Organic Agriculture Consortium, 2000 - 2005

The Organic Agriculture Consortium (OAC) was established in September 2000 with a $1.8 million grant, “Revitalizing Small and Midsize Farms: Organic Research, Education, and Extension,” from the USDA Initiative for Future Agriculture and Food Systems (IFAFS) program. Partners in the consortium are The Ohio State University, Iowa State University, North Carolina State University, Tufts University, the Organic Farming Research Foundation (OFRF), and leading organic farmers. The goal of the OAC is to assist farmers with small to midsize operations to transition from conventional to organic production systems through integrated multidisciplinary research, education, and outreach programs.

Please see OAC Accomplishments and Impacts for more information about the Consortium. Scientific abstracts presented at the final OAC meeting in August 2005 are listed below.
