Soil electrical resistivity measurement: from terroir characterization to within-field crop inputs management

Abstract

Soil Electrical Resistivity measurement is a zoning tool used by soil scientists and agronomists in viticulture. Indeed, the measure enables to optimize pedological surveys (position and number of soil sampling) to obtain a very precise final soil map. Since 2007, Tutiac Winegrowers (Vignerons de Tutiac, Bordeaux) have decided to map all their vineyards (over 4000 hectares) with this technology. Maps are used by the Winery to provide advices more suited to the terroir: grass cover, fertilization, replanting (grape variety/rootstock), grape selection and to define the potentiality of each plot regarding market expectations. However, because of logistic reasons, the Tutiac Winery is not able to use the very high-resolution of the maps for within-field valorization (selective harvest). But, intra-block information of resistivity maps, crossed with complementary measures, can be used in a different way, in particular to cut down use of phytosanitary treatment. This paper presents the GIPI project which plans to vary the rate of crop inputs inside the field. Agronomic (input data, abacus) and technological aspects (software, direct injection sprayer) will be described through an example of a vineyard (25 hectares) where many measurements (resistivity, pedology, NDVI…) have been carried out.

Influence of social interaction levels on panel effectiveness in developing wine sensory profiles using consensus method

The development of sensory profiles is crucial for quality control and innovation in the wine industry. If quantitative descriptive analysis is the most commonly used method for establishing sensory profiles due to its robustness, it presents significant limitations.

Application to the wine sector of European Convention on the landscapes

The landscape is defined by the European convention of the landscape (Florence, October 20, 2000) like part of the territory as perceived by the populations, whose character results from the action of natural and/or human factors and their interrelationships. This convention is based on the contribution cultural, ecological, environmental, social of the landscapes and aims at a reinforcement of the tools of protection and valorization in particular in the agricultural policies, of regional planning and town planning. Moreover, it encourages a step of identification and qualification of the landscapes and underlines the need for developing the sensitizing and the training of the actors concerned.

The grapevine QTLome is ripe: QTL survey, databasing, and first applications

Overarching surveys of QTL (Quantitative Trait Loci) studies in both model plants and staple crops have facilitated the access to information and boosted the impact of existing data on plant improvement activities. Today, the grapevine community is ready to take up the challenge of making the wealth of QTL information F.A.I.R.. To ensure that all valuable published data can be used more effectively, the myriad of identified QTLs have to be captured, standardised and stored in a dedicated public database.
As an outcome of the GRAPEDIA initiative, QTL-dedicated experts from around the world have gathered to compile the grapevine QTLome: the complete information (e.g., map positions, associated phenotypes) describing all experimentally supported QTLs for a specific trait.

Texas terroir: gis characterization of the texas high plains ava

The Texas High Plains AVA is one of eight officially recognized wine regions in Texas, established in 1993. Six local wineries, including the second-largest in Texas, are supported by approximately 50 vineyards, which are also major suppliers of grapes to Texas wineries outside the region.

Influence of nitrogen supply on colorimetric parameters of Lugana wines

Color is one of the main qualitative parameters of a wine. As a matter of fact, immediately after having opened a bottle of wine, color, even before aroma and taste, is the first sensorial parameter to be evaluated by the consumer It can change according to various factors depending on the characteristics of the grapes or on the different production and storage processes.
