Unexpected relationships between δ13C, water deficit, and wine grape performance

Water nutrition is crucial for wine grape performance. Thus soil investigation aims at characterizing spatial and temporal variability of available water. A possible strategy is to integrate monitoring and proxies of water availability. The carbon isotope ratio δ13C, measured in the alcohol of wine, is a promising tool to determine water stress during the vine […]

Impact of organic inputs on soil biodiversity in vineyard systems. A monitoring approach during 20 years

Conventional vineyard practices have lead in many environmental disturbances as erosion, soil compaction, loss of organic matter and soil biodiversity, water contamination… Therefore, there is an increasing interest to develop sustainable viticulture in the famous Champagne vineyard for 20 years: a program called “VITI 2000” has been developed since 1986 by CIVC (Inter-professional Committee of […]

Mapping intra-plot topsoil diversity of Burgundy vineyards (Aloxe-Corton, France) from very high spatial resolution (VHSR) images

In this work, we present a method based on very high spatial resolution (VHSR) aerial images acquired in the visible domain and that map soil surface diversity at the hillslope scale with a spatial resolution of a few centimeters. This method combines aerial VHSR image classification with local soil sampling. Principal component analysis (PCA) and […]

Contribution of soil for tipifiyng wines in four geographical indications at Serra Gaúcha, Brazil

Brazil has a recent history on geographical indications and product regulation for high quality wines. The first geographic indication implemented was the Vale dos Vinhedos Indication of Procedence (IP), within the wine production zone named Serra Gaúcha, northeast of State Rio Grande do Sul. During the last decade, the Vale dos Vinhedos ascended to the […]

Soil chemistry as a measure of the distinctiveness of american viticultural areas of the Columbia basin, USA

The Columbia Basin, a semi-arid region centered in the eastern part of Washington State, is the second largest wine grape growing region in the United States and presently contains 10 American Viticultural Areas (AVAs). Eight of the Columbia Basin’s AVAs are smaller subdivisions (sub-AVAs) of the 46,100 km2 Columbia Valley AVA. Although legally distinct, the […]

Grapegrowing soils

The soil plays a key role in viticulture since it defines the planting depth, development and aeration of the root system and also controls the absorption of mineral elements and water conditions of the plant (1). Topography has been considered a determinant of the quality of wine from the Roman Empire; however, the classical treatises […]
