Six community supported agriculture farms will participate Saturday in Campbell's Nutrition CSA Fair, from 11 a.m. to 2 p.m. at Campbell's Nutrition, 4040 University Ave. The CSA Fair is organized by Greater Des Moines Buy Fresh Buy Local, Eat Greater Des Moines, and Iowa Heartland Resource Conservation and Development. The event provides people with the opportunity to meet with local farmers directly, to learn more about CSA.  Employers can work with the groups to have vegetables delivered directly to workplaces for employees.
