Just south of San Francisco lies California's Salinas Valley, the heart of a multibillion dollar agricultural industry that dominates U. S. vegetable production. How did the sleepy valley described in the stories of John Steinbeck become the nation's "salad bowl"? In Cultivating Science, Harvesting Power,Christopher R. Henke explores the ways that science helped build the Salinas Valley and California's broader farm industry. Henke focuses on the case of University of California "farm advisors," scientists stationed in counties throughout the state who have stepped forward to help growers deal with crises ranging from labor shortages to plagues of insects. These disruptions in what Henke terms industrial agriculture's "ecology of power" provide a window onto how agricultural scientists and growers have collaborated—and struggled—in shaping this industry. Through these interventions, Henke argues, science has served as a mechanism of repair for
