摘要

While the management of apple orchards is intensifying through high tree density, heavy input use and short lifespan, growers in some traditional production areas keep on planting semi-extensive orchards. We assessed the environmental impacts of those two contrasted production systems using the last methodological recommendations for Life Cycle Assessments (LCA) in perennial crops. The use of such framework permitted to assess the weight of the unproductive stages in the orchard lifespan impacts, and the contribution of fertiliser direct field emissions to the total impacts.
