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


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.

The impact of global warming on Ontario’s icewine industry

Ontario’s wine regions lie at the climatic margins of commercial viticulture owing to their cold winters and short cool growing season. The gradual warming of northern latitudes projected under a human-induced climate change scenario could bring mixed benefits to these wine regions.

Phenolic composition and chromatic characteristics of blends of cv. Tempranillo wines from vines grown with different viticultural techniques in a semi-arid area

The quality and color stability of red wines are directly related to content and distribution of phenolic compounds. However, the climate change produces the asynchrony between the dates of technological and maturity of grapes. The crop-forcing technique (CF) restores the coupling between phenolic and technological ripeness while limits vineyard yields. Blending of wines is frequently used to equilibriate composition of wines and to increase their stability, color and quality. The aim of the present work is to study the phenolic composition and color of wine blends made with FW (wines from vines subjected to CF) and CW (wines for vines under the usual cultivation practices).

Impact of aging on dimethyl sulfide (DMS) in Corvina and Corvinone wines

Amarone is an Italian red wine produced in the Valpolicella area, in north-eastern Italy. Due to its elaboration with withered grapes, Amarone is a rather unique example of dry red wine. However, there is very limited data so far concerning the volatile composition of commercial Amarone wines, which also undergo a cask aging of 2-4 years before release. The present work aims at characterizing the aroma composition of Amarone and to elucidate the relationships between chemical composition and sensory characters.

Characteristics of some Montefalco Sagrantino vineyards through polyphenolic components

Characteristics related to the climate and the soil of Montefalco in the centre of Italy have been defined in order to evaluate their influence on the red cv.

Optimised extraction and preliminary characterisation of mannoproteins from non-Saccharomyces wine yeasts

The use of non-Saccharomyces yeast species for the improvement of wine technological and oenological properties is a topic that has gained much interest in recent years [1]. Their application as co-starter cultures sequential to the inoculation of Saccharomyces cerevisiae and in aging on the lees has been shown to improve aspects such as protein stability and mouthfeel [2].
