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.

Evaluation of the composition of pomace from grapes grown in the slopes of the Popocatépetl volcano (Puebla, Mexico). Feasibility of its application for obtaining functional foods

Grape pomace is the main byproduct generated during wine production and is primarily composed of skins and seeds, which are obtained after the pressing stage [1]. This byproduct retains a significant amount of nutrients, such as fiber, phenolic compounds, unsaturated fatty acids, vitamins, and minerals.

The key role of vineyard parcel in modifying flavor compounds of Cabernet Sauvignon grapes

To produce premium wines in a specific region is the goal of local oenologists. This study aimed to investigate the influence of soil properties on the flavoromics of Cabernet Sauvignon grapes to provide a better insight into single-vineyard wines. Six commercial Cabernet Sauvignon vineyards were selected in the Manas region to collect berries at three harvest ripeness in three seasons (2019–2021). The six vineyards had little difference in mesoclimate conditions while varying greatly in soil composition.
