The living soil of the Champagne vineyards (VITIECOBIOSOL)

The living soil of the Champagne vineyards (VITIECOBIOSOL)

Summary
In Champagne vineyards as in the others, it is vital to maintain or improve soil quality through the selection of appropriate agro-viticultural practices. This necessarily requires the active involvement of all stakeholders. The Champagne wine profession has developed an environmental management system across the area AOC. Four major issues have been identified, including two related soils through the flap "control nuisances and risks relating to the use of inputs" and "preservation and development of Terroirs, Biodiversity and Landscapes".
Our VitiEcoBioSol project reflects the implementation of a applied research in close collaboration between representatives of the agri-development of AOC wine Champagne and researchers on soil biology (microorganisms and macrofauna earthworm). This "operational" approach fits consistently in the conceptual model GESSOL program. lt permits to show how the research come in support of environmental policies and contribute to the development of advice which has changed viticultural practices between 1985 and 2010, in the Champagne
vineyards.
Our VitiEcoBioSol project addresses two main questions:
- what are agro-viticultural practices that best preserve the soil, their biodiversity and associated ecosystem services contribute?
- how aware the wine profession to these issues and how change the advice and the practices across the AOC Champagne?
This project has detailed objectives:
1 - building a first referential for interpretation of the impact of viticultural practices on microbial and earthworm activities of Champagne vineyard soils
2 - critical analysis of the impact of agri-environmental policy on the AOC Champagne from 20-25 years (in terms of evolution of the written advice)
3 - building of media awareness for winemakers and field operators to ensure the inclusion of these soil biological activity in new forms of sustainable management of the vineyard.
The direct involvement of professional players is a unique feature of this project. The outputs of this project (reference on the evolution of biological conditions of the soil in relation to the most common viticultural practices & media awareness) will enable winemakers to appropriate firstly the tools to characterize the biological state of their soil, and secondly the concepts and vocabulary related to the conservation and management of biodiversity in the vineyard soils.
In conclusion and perspectives, we present the results of the first actions of participatory research initiated since 2010 to extend the first referential of soil biodiversity to all the vineyards of Champagne, or even to other vineyards.
