In a two-year experiment, agroecological service crops (ASCs) introduction before organic zucchini and lettuce vs no-ASCs (CT), and two ASCs termination strategies (green manure, GM vs roller crimper, NT) were compared. The objective was to assess the environmental sustainability in a Mediterranean environment. Agronomic performance, energy analysis and carbon footprint were assessed. Although lower zucchini and lettuce yields than GM, the NT strategy was more sustainable than GM and CT, showing energy efficiencyof 0.64, 0.31 and 0.13%, respectively, and showing the highest carbon stored in the soil. NT can reach a good compromise between crop production and impact of agricultural activities.
