Visiting the oldest European agroforestry experimental site at Restinclières, featuring 25 years of research in collaboration with farmers. In the lowlands, cereals (durum wheat in rotation with protein pea) are cultivated in silvoarable agroforestry with walnut and other trees (sorb, ash, hackberry, wild cherry…). In the more stony soils, grapevine is associated with sorb, pine and cypress.
