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).

Methodology to assess vine cultivation suitability using climatic ranges for key physiological processes: results for three South African regions

Le climat a de fortes implications sur le bon fonctionnement physiologique de la vigne et a besoin d’être quantifié afin de déterminer l’aptitude des régions à la culture de la vigne. Une méthode, qui pourrait éventuellement servir à prévoir l’aptitude des régions à la culture de la vigne, est proposée.

Screening of Italian red wines for quercetin precipitation risk index

Quercetin (Q), a phenolic compound released from grape skins during red wine maceration, has been identified as a source of instability in bottled wines, particularly Sangiovese, due to crystallisation. This phenomenon represents an economic challenge for producers and affects wine clarity and consumer perception.

Distribution and associated symptoms of grapevine trunk pathogens in South Africa

In recent studies, several grapevine trunk pathogen complexes have been identified from grapevines in South Africa. These pathogens include Eutypa lata, Phaeomoniella chlamydospora, Phaeoacremonium sp., Botryosphaeria sp. and Phomopsis sp. Trunk diseases lead to reduced yield, and grape quality as well as a decline

Assessing macro-elements contents in vine leaves and grape berries of Vitis vinifera using near-infrared spectroscopy coupled with chemometrics

The cultivated vine (Vitis vinifera) is the main species cultivated in the world to make wine. In 2017, the world wine market represents 29 billion euros in exports, and France contributes 8.2 billion (28%) to this trade, making it a traditional market of strategic importance. Viticulture is therefore a key sector of the French agricultural economy. It is in this context that the nutritional diagnosis of the vine is of real strategic interest to winegrowers. Indeed, the fertilization of the vine is a tool for the winegrower that allows him to influence and regulate the quality of the wine.
