Eliot Coleman is an organic farmer and a writer in Maine who has helped popularize the idea of four-season farming.His ideas about hoop houses sounded good to John Biernbaum in the Horticulture(园艺)Department at Michigan State University.
Professor Biernbaum tried hoop houses on the Student Organic Farm at Michigan State and had success.Project director David Conner says it was a“test drive(试车)”for the research on private farms.The agricultural economist points to the demand for locally grown crops.“People are hungry for good,fresh vegetables,”he says.
