In Mediterranean regions, the strong inter-annual variability of rain regime makes difficult the achievement of stable agronomic and environmental performances in vineyards. It is due to both the conditions of winter soil water refilling and the water balance during grapevine vegetation cycle. Soil surface management offers technical control levers to manage water balance. Simulation-assisted design of strategies of soil surface management demonstrates that, on series of contrasted climatic years, adaptive strategies lead to changing nature, number and timing of technical operations, and to fairly stable resulting agronomic performances (yield, quality of products) and environmental impacts.
