Effets des pratiques agro-viticoles sur l’activité biologique et la matière organique des sols : exemples en Champagne et en Bourgogne

Abstract

The notion of terroir covers multiple components, from geology, pedology, geomorphology and climatology (Doledec, 1995), to less well-identified aspects but also intervening in the “typicality” of wines. This justifies the “zoning” approach (Moncomble and Panigaï, 1990) to define homogeneous areas, under the same agro-viticultural management and also identified at the product level (Morlat and Asselin, 1992).

Cultivation practices form a component of the “terroir” which should not be neglected because it can be modified by human action. It is therefore necessary to know the consequences of the technical itineraries well, in order to be able to choose them according to the fixed data of the terroir and the desired characteristics of the product.

In this respect, soil maintenance techniques are certainly the most interesting to study, because of their interactions with water supply and vine nutrition. Such interactions have already been studied by viticultural monitoring (Soyer et al ., 1995; Aguhlon and Voile, 1995), but very little work has been devoted to direct measurements on the soil. This is what we have sought to do in the present work, relying on the experimental devices of Plumecoq and Montbré in Champagne and Mâcon-Clessé in Burgundy.

More broadly, our objective is to participate in promoting sustainable management of vineyard soils compatible with quality products. It is in fact a question of researching the most suitable cultural practices for:
1) conserve soils, in the face of “a worrying reactivation of erosion” (Roose, 1994)
2) control their characteristics linked to fertility (structure, organic reserves, biological activities, availability of nitrogen and water ).

The terroir of Carnuntum: investigation of the physiogeographic characteristics and interdisciplinary study of viticultural functions of the Carnuntum wine district, Austria

During a three-year period, the vineyards of the Carnuntum wine district are investigated for their terroir characteristics. The interdisciplinary study is aimed at the description of the physiogeographic

Learning from remote sensing data: a case study in the Trentino region 

Recent developments in satellite technology have yielded a substantial volume of data, providing a foundation for various machine learning approaches. These applications, utilizing extensive datasets, offer valuable insights into Earth’s conditions. Examples include climate change analysis, risk and damage assessment, water quality evaluation, and crop monitoring. Our study focuses on exploiting satellite thermal and multispectral imaging, and vegetation indexes, such as NDVI, in conjunction with ground truth information about soil type, land usage (forest, urban, crop cultivation), and irrigation water sources in the Trentino region in North-East of Italy.

Harnessing whole genome sequencing data to predict protein structure and function variation in grapevine

Grapevine (Vitis vinifera) is amongst the world’s most cultivated fruit crops, and of global and economic significance, producing a wide variety of grape-derived products, including wine, and table grapes. The genus Vitis, encompassing approximately 70 naturally occurring inter-fertile species, exhibits extensive genetic and phenotypic diversity, highlighted by the global cultivation of thousands of predominantly Vitis vinifera cultivars. Despite the importance of harnessing its naturally occurring genetic diversity to pursue traits of interest, especially considering the continued and growing demand for sustainable high-quality grape production, the systematic characterization of available functional genetic variants remains limited.

Vitis vinifera Manseng noir is an alternative red variety for low alcohol wines of strong structure and soft tannins

In 2019, we have planted the red variety Manseng Noir, as it has been shown that it is the only sister of the Tannat grape. Tannat was introduced to Uruguay in 1870 from the south-western regions of France.

Somatic embryogenesis and organogenesis: driving regeneration forces behind grapevine genetic transformation

Cell pluripotency, enables the possibility to change the cellular fate, stimulating the reorganization and the formation of new vegetative structures from differentiated somatic tissues. Although several factors are implicated in determining the success of a breeding program through the use of modern biotechnological techniques, the definition of a specific regeneration strategy is fundamental to speed up and make these applications feasible.
