Situational analysis of green manure practices implemented in Gaillac vineyard

Abstract : Green manuring has shown interesting potentials to increase soil organic matter. It consists in cover cropping intermediaries crops that accumulate biomass. This biomass will be released after cover crop death and available for the subsequent crop. Innovative green manure practices are burgeoning in Gaillac vineyard but still require technical references and assessment of potential services provided. This study aimed at collecting technical information and decision rules of the soil management itineraries associated with these GM uses. An online survey has been carried out and allow to describe 46 soil management itineraries. A field campaign at green manure destruction period on 16 plots of Gaillac vineyard gave an illustration of green manure performances, in relation with technical choice and pedoclimatic context. This study finally allowed to build typologies of green manure uses and to census winegrowers’ needs in terms of research on green manure. Such multi-species agroecosystems call for management tool in order to tackle the complexity of interactions.
