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.

Diversity and internationalization of wine grape varieties: Evidence from a revised global database

Aim: To quantify the extent to which national mixes of wine grape varieties (in terms of vineyard bearing area) have become more or less diversified, and ‘internationalized’, since wine globalization accelerated from the 1990s.

Climatic zoning and viticulture in Galicia (North West Spain)

Galicia is situated in the NW of the Iberian Peninsula, just north of Portugal and so sharing a mild, maritime climate, certain vine species and a number of long-standing viticultural traditions. In Galicia about 18,000 has are dedicated to wine growing, of which roughly half (46%) correspond to the 6 DOs in the area.

The geological and geomorphological events that determine the soil functional characters of a terroir

The geology of a region is deemed to be an important component of terroir, as it influences the shape of the landscape and the climate of vineyard. The nature of rock and the geomorphological history of a terroir affect soil physical and chemical composition through a dynamic interplay with the changes of climate, vegetation and other living organisms, as well as with man activities.
