Soil survey and chemical parameters evaluation in viticultural zoning

Abstract

The most recent methodological developments in soil survey and land evaluation, that can be taken as reference in the viticultural field, go over usage of the GIS and database. These informatic tools, which begin to be widely utilised, consent to realise evaluations at different geographic scale and with different data quality and quantity in entrance.
Realising a territorial study with zoning purposes however, it is always necessary to respect the coherence between aims of work, scale of considered processes, intensity of survey and evaluation model utilised. Thus, the less detailed the scale of investigation, the lower the degree of purity and confidence of geographical information, and the more generic the evaluations.
On the other hand, the way of dealing with the typological information should be different. If the soil survey model individualises soil typologies corresponding to soil series, il is possible to find the soil characters that can be functional for viticultural and oenological results, and the geographic levels at which they can be pointed out.
ln the present work, an example is brought of the possible treatment of information at different geographic generalisation levels, utilising data of some chemical analysis and a soil survey realised in Trentino (northern Italy).

Carbon isotope discrimination in berry juice sugars: changes in response to soil water deficits across a range of vitis vinifera cultivars

In wine producing regions around the world, climate change has the potential to decrease the frequency and amount of precipitation and increase average and extreme temperatures. This will lower soil water availability and increase evaporative demand, thereby increasing the frequency and intensity of water deficit experienced in vineyards. Among other things, grapevines manage water deficit by regulating stomatal closure. The dynamics of this regulation, however, have not been well characterized across the range of Vitis vinifera cultivars. Providing a method to understand how different cultivars regulate their stomata, and hence water use in response to changes in soil water deficits will help growers manage vineyards and select plant material to better meet quality and yield objectives in a changing climate.

SO2 consumption in white wine oxidation: approaches to low-input vinifications based on rapid electrochemical analyses and predictive enology

Oxidative stability is a critical factor in wine shelf-life. SO₂ is commonly added to wine due to its strong antioxidant activity, although there is a general push to reduce SO₂ use in vinification.

Grapevine nitrogen status: correlation between chlorophyll indices n-tester and spadGrapevine nitrogen status

Knowledge of the nitrogen nutrition status of grapevines is essential for the sustainable management of their nutrition for the production of quality grapes. The measurement of the chlorophyll index is a rapid, non-destructive and relatively inexpensive method that provides a good approximation of the nitrogen nutrition status of the vine during the season. Interpretation thresholds are currently insufficient or non-existent for some chlorophyll meters. Ideally, they should be available for each variety and each phenological stage. In order to popularize the use of chlorophyll-meters, measurements were carried out at Agroscope in Switzerland to establish the correlation between the indices obtained by the devices N-tester and SPAD 502.

Consumer perception of wine bottle weight and its impact on sustainability

In the context of sustainability, this study evaluated consumer perception regarding the impact of glass bottle weight on wine valuation.

Organic volatile compounds as suitable markers of grapevine response to defense elicitors in the vineyard

In greenhouse, emission of volatile organic compounds (VOC) by grapevine leaves has already been reported in response to the defence elicitor sulfated laminarin (PS3) [1]. In order to check that this response was not specific to PS3, experiments were conducted on Vitis cv Marselan plantlets with several other elicitors of different chemical structures: i.e. Bastid® (COS-OGA),
