Étude sur la restauration et le maintien de la vigueur de la vigne sous différentes stratégies de fertilisation et d’entretien du sol

Abstract : In a context of pratices’ evolution to more sustainable pratices, a lot of Vignerons and Maisons have given up herbicides and modified their pratice of fertilisation and of the maintenance of the soil. Yet, these new agronomic models have generated new ecophysiological difficulties as the decrease of vigour or yields. The aim of thise study is to understand which strategies of fertilisation or maintenance of the soil allowed to restorate or maintain vines’ vigor. To achieve this aim, a set of ecophysiologic, soil and climate conditions indicators have been chosen and followed on a network of six parcels dispersed trought Champagne representing the three main grape varieties of the AOC. Tow years of ecophysiological data have been cross-referenced to climate and soil data as well as vineyard management pratices to try to understand which pratices were more efficient to maintain vigor. This study has been done on two scales, the first one inter-plot to understand overall which pratices are the most efficient. The second one at a plot scale to determine which pratices are the most relevant according to the soil and climate condictions.
