Soil electrical resistivity, a new and revealing technique for precision viticulture

Abstract

High resolution spatial information of soil electrical resistivity (ER) was gathered to assess the spatial variability patterns of vegetative growth of two commercial vineyards (Vitis vinifera L. cv. Tempranillo) located in the wine-producing regions of La Rioja and Navarra, Spain. High resolution continuous geoelectrical mapping was accomplished by an Automatic Resistivity Profiler (ARP) on-the-go sensor with an on-board GPS system; rolling electrodes enabled ER to be measured for a depth of investigation approximately up to 0.5, 1 and 2 meters. Contemporarily, in specific locations within the vineyard plots, soil samples were taken and physical soil analyses were performed in the laboratory. ER was related to spatial and temporal variabilities of a number of physical soil properties, such as salinity, clay mineral content and soil moisture. Resistivity data were interpolated over the whole area by means of the Ordinary Kriging interpolation algorithm, producing raster maps with a 5-m cell size. A correlation matrix was then employed to find out the most significant relationships between ER, soil physical and vegetative growth data. In conclusion, ER is a useful technique to identify areas with similar vegetative status within a vineyard in the frame of precision viticulture.

Analisi delle modalita’ d’interazione tra conoscenza dl un territorio e gestione dei suoi aspetti enoturistici relativamente ad una regione (Toscana)

Il Turismo negli anni 2000 si appresta ad essere la più vasta ed estesa impresa presente nel mondo. Se a cio si aggiunge il fatto che il tempo libero risulta essere, per la maggior parte delle persone, la principale aspirazione da considerare ben oltre il proprio benessere eco­nomico, ci si rende conto del perché di una crescente domanda di ecoturismo. Un viaggiare sempre più accorto aile valenze ambientali e tipiche di un territorio.

Assessing the Effectiveness of Electrodialysis in Controlling Brettanomyces Growth in Wine

Brettanomyces yeast can negatively impact the quality and stability of wines, posing a significant challenge to winemakers. [1] This study aims to develop novel management practices to limit Brettanomyces impact on wines by evaluating the effectiveness of electrodialysis (ED) technology in removing magnesium (Mg2+) from wine to prevent the development of Brettanomyces yeast. The ED technique utilizes charged membranes to extract ions from the wine, and it is considered an alternative to cold stabilization that requires less energy. [2]

Viticultural zoning of the country of Mendoza, Argentina. Study of the first zone : department of Luján de Cuyo. Statement of the study year 2002

La région viticole de Mendoza est la principale zone vitivinicole d’Argentine qui se compose de 3 oasis (Nord, Valle de Uco, Sud). La première zone vitivinicole, située dans l’oasis Nord, est composée par les département de Luján de Cuyo et Maipu. C’est la zone de production la plus ancienne et la plus reconnue pour la qualité de sa production. Ce travail se porte plus particulièrement sur le département de Luján de Cuyo qui constitue le lieu traditionnel de production du Malbec argertin. Ce travail propose de caractériser les terroirs et de mettre en avant leurs typicités.

Volatile Organic Compound markers of Botrytis cinerea infection in artificially inoculated intact grape berries

The addition of partially dehydrated grapes to enrich must composition for producing complex dry/sweet wines represents a traditional practice in several regions of the world. However, the environmental conditions of dehydration chambers may facilitate the infection of Botrytis cinerea Pers. by promoting disease and provoking large grape losses. B. cinerea attack can induce alterations in the profile of volatile organic compounds (VOCs), which could be detected by sensors specifically trained to detect infection/disease-related compounds. These sensors could facilitate the early detection of the infection, consequently allowing to adjust some dehydration parameters.
