From local classification to regional zoning-the use of a geographic information system (GIS) in Franconia / Germany. Part 1: specific GIS applications in viticulture

Abstract

[English version below]

En vue d’une production économique de qualités des raisins optimales une connaissance des informations les plus différentes est importante. Les nouvelles technologies, telles qu’un SIG permettent de réunir les informations sur le terrain, la nature du sol, le danger d’érosion, le climat, la végétation, l’hydrographie, l’apparition de nuisible et de maladies, etc. Sur la base de cartes topographiques un SIG permet une vaste analyse, une appréciation des rapports complexes ainsi qu’une représentation cartographique. Sur la base de modélisations en trois dimensions du terrain avec le SIG, les ensembles de données saisies ainsi que leur classification au niveau local peuvent être utilisés dans la production de zonages régionaux. Les données du SIG délivrent des informations liées à la protection du sol et de l’eau, la classification climatique, la protection de la vigne, la possibilité d’enherbement, la planification d’irrigation, etc. Les aspects principaux de l’utilisation du SIG en Franconie sont l’enregistrement et l’analyse des données locales, comme les paramètres du sol, le risque d’érosion et les conditions climatique, dans le but d’élaborer des classifications locales des zones à appellation communale et des petits terroirs. A l’aide du SIG, ces classifications locales permettent la création de zonages régionaux, comme par exemple la formation de cartes régionales du risque d’érosion ou la définition de zones de climat local. La modélisation du terrain en trois dimensions permet de déterminer les couloirs d’écoulement de l’air froid et la modélisation des régions soumises au risque de gel, comme les creux et les vallées. Pour cette raison, le SIG en viticulture est un excellent instrument de travail dans la recherche et la consultation viticole ainsi que pour les producteurs de raisins et des domaines viticoles afin d’enregistrer, d’analyser et d’évaluer les influences que des zones régionales déterminées ont à subir. Ainsi le SIG montre aux vignerons leurs surfaces viticoles sous une perspective permettant de mieux analyser le milieu.

For an economically production of optimal grape quality, the knowledge of different types of information is important. New computer software such as a GIS enables the compilation of information on topography, soil, erosion risk, climate, vegetation, infrastructure, and the occurrences of pests and diseases. Based on digital topographie maps, a GIS allows a synoptical analysis of complex correlations and their representation on maps. Based on a three-dimensional terrain modelling with the GIS, recorded data sets and their local classification can be used to establish a regional zoning of viticultural relevant factors as e.g. favourable climatic zones combined with best soil conditions. The GIS data deliver information for fields like soil and water conservation, climatic classification, vine protection, selection of suitable grape varieties and rootstocks, green cover capacity, irrigation planning, yield and quality recording, etc. Main objectives of the GIS application in Franconia are the recording and analysis of local data sets as soil parameters, erosion risk and climatic conditions in vineyard sites. With help of the GIS, these local information enables the creation of a regional zoning of the respective data set, e.g. the generation of regional erosion risk maps or the definition of regional climatic zones. The 3D-terrain modelling allows the determination of flow-off paths of cold air and ‘mapping’ of frost endangered areas like depressions and valleys. Therefore, the viticultural GIS is an excellent aid to researchers and consultants, grape producers and wine growing estates for recording, analysing and assessing viticultural relevant factors in vineyards. This enables a new perspective of vineyards for a better planning of new plantings and also for an improvement of the vineyard management.

Impact of changes in pruning practices on vine growth and yield

A gradual decline in vineyards has been observed over the past twenty years worldwide. This might be explained by the climate change, practices change or the increase of dieback diseases. To increase the longevity of vines, we studied the impact of different pruning strategies in four adult and four young vineyards located in France and Spain. In France, vineyards were planted with Cabernet franc on 3309C while Spanish trials were planted with Tempranillo grafted on 110R. Vegetative expression, yield, quality of berries and wood vessels conductivity were measured. The distribution of vegetative expression, yield and berry composition between primary and secondary vegetation were quantified. Finally, tomography was used to evaluate the implication of the treatments on sap flows. First results show that i) the respectful pruning leads to an increase of 30 to 50% more secondary shoots than the aggressive pruning in France and between 15 and 20% in Spain, ii) there is no major effect on the yield over the first two years following the implementation of the new pruning practices, although the proportion of clusters from suckers is higher on the respectful pruning method. On young vines, the development of the trunk according to a respectful pruning leads to a loss of harvest 2 years after planting. This is due to the removal, on the future trunk, of the green suckers which carrying bunches. This operation carried out in spring rather than during winter pruning, would promote a better leaf / fruit balance when the plant comes into production, and could lead to better hydraulic conduction in the vessels of the trunk. Maintaining these trials for several years will provide more robust data to assess the impact of these practices on the vines over the long term.

Mesoclimate impact on Tannat in the Atlantic terroir of Uruguay

The study of climate is relevant as an element conditioning the typicity of a product, its quality and sustainability over the years. The grapevine development and growth and the final grape and wine composition are closely related to temperature, while climate components vary at mesoscale according to topography and/or proximity to large bodies of water. The objective of this work is to assess the mesoclimate of the Atlantic region of Uruguay and to determine the effect of topography and the ocean on temperature and consequently on Tannat grapevine behavior.

Measurement of redox potential as a new analytical winegrowing tool

Excell laboratory has initiated the development of an analytical method based on electrochemistry to evaluate the ability of wines to undergo or resist to oxidative phenomena. Electrochemistry is a powerful tool to probe reactions involving electron transfers and offers possibility of real-time measurements. In that context, the laboratory has implemented electrochemical analysis to assess oxidation state of different wine matrices but also in order to evaluate oxidative or reduced character of leaf and soil. Initially, our laboratory focused on dosage of compounds involved in responses of plant stresses and we were also interested in microbiological activity of soils. These analyses were compared with the measurement of redox potential (Eh) and pH which are two fundamental variables involved in the modulation of plant metabolism. Indeed, the variation of redox states of the plant reflects its biological activity but also its capacity to absorb nutriments. The Eh-pH conditions mainly determine metabolic processes involved in soil and leaf and our goal is to determine if this combined analytical approach will be sufficiently precise to detect biological evolutions (plant health, parasitic attack…).

Current climate change in the Oplenac wine-growing district (Serbia)

Serbian autochthonous vine varieties Smederevka (for white wines) and Prokupac (for rosé and red wines) are the primary representatives of typical characteristics of wines and terroir of numerous wine-growing areas in Serbia. In the past, these varieties were the leading vine varieties, however, as the result of globalization of winemaking and the trend of consumption of wines from widely prevalent vine varieties, they were replaced by introduced international varieties. Smederevka and Prokupac vine varieties are characterized by later time of grape ripening, and relative sensitivity to low temperatures. Climate conditions can be a restrictive factor for production of high-quality grapes and wine and for the spatial spreading of these varieties in hilly continental wine-growing areas.
This paper focuses on the spatial analysis of changes of main climate parameters, in particular, analysis of viticultural bioclimatic indices that were determined for the purposes of viticulture zoning of wine-growing areas in the period 1961-2010, and those same parameters determined for the current, that is, referential climate period (1988-2017). Results of the research, that is, analysis of climate changes indicate that the majority of examined climate parameters in the Oplenac wine-growing district improved from the perspective of Smederevka and Prokupac vine varieties. These studies of climate conditions indicate that changes of analyzed climate parameters, that is, bioclimatic indices will be favorable for cultivation of varieties with later grape ripening times and those more sensitive to low temperatures, such as the autochthonous vine varieties Smederevka and Prokupac, therefore, it is recommended to producers to more actively plant vineyards with these varieties in the territory of the Oplenac wine-growing district.
