The “resources profile®”: a relevant decision and support system for adapting viticultural practices to soils agronomic properties and limiting their environmental impacts

Abstract

Soil is a three-dimensional complex system, which constitutes a major component of Terroir. Soil characteristics strongly influence vine development, grape oenological potentialities and thus wine quality and style.

Soil profile description by means of pits is essential for a relevant characterization of the soil. However, the interpretation of results is very difficult for non-specialists, as for most of advisors or winegrowers, due to the multitude of parameters and their variability within the soil profile.

We propose here a novel method to represent soil parameters variability, integrating thickness and depth of the different horizons, providing an operational Decision and Support System (DSS) for winegrowers and advisors.

For each parameter, soil profile is represented by a vertical block divided in 10 centimeters layers, in order to highlight the thickness of the different horizons. According to the parameter value, a specific color code, based on analytical references, is applied for each horizon. This method has been applied on different soil parameters : coarse fragments content, clay content, slaking and compaction index, carbonate content, pH, organic content and stock, carbon/nitrogen ratio, cation exchange capacity, exchangeable cations contents, base saturation percentage.

This method, called « Resources Profile® », has been tested on a large number of soil types, representative of soils variability in Bordeaux wine production area (France). It allows to easily visualize soil parameters variability within soil profile and to evaluate agronomic properties, such as hydrological soil properties, organic and calcic status, mineral resources or degradation sensitivities.

We believe that the « Resources Profile® » is a relevant DSS for adapting viticultural practices to soils characteristics and for limiting their environmental impacts. This DSS is likely to facilitate the spread of soil science knowledge to the vinegrowing industry.

Berry carbon (δ13C) and nitrogen (δ15N) isotopic ratio reflects within farm terroir diffferences

ÂThe natural abundance of carbon stable isotopes has been reported to be related to water availability in grapevines quite widely. In the case of nitrogen, the natural abundance of its stable isotopes is mainly affected by the nature of the source of nitrogen (organic vs. inorganic) used by the plant, though the bibliography available for grapevine is very scarce.

Elicitors used as a tool to increase stilbenes in grapes and wines

The economic importance of grapevine as a crop plant makes Vitis vinífera a good model system to study the improvement of the nutraceutical properties of food products (Vezulli et al. 2007). Stilbenes in general, and trans-resveratrol in particular, have been reported to be responsible for various beneficial effects. Resveratrol´s biological properties include antibacteria and antifungal effects, as well as cardioprotective, neuroprotective and anticâncer actions (Guerrero et al. 2010 ). Stilbenes can be induced by biotic and abiotic elicitors since they are phytoalexins (Bavaresco et al. 2001).

Aromas of Riesling wine: impact of bottling and storage conditions

Storage temperature and bottling parameters are among the most important factors, which influence the development of wine after bottling. It is well studied that higher storage temperatures speed up chemical reactions and results in faster wine aging [1,2]. It is also known that higher SO2 level and lower oxygen content provide better protection and longer shelf-life for the wine. At the same time, the mechanisms of chemical transformations of wine aromas during the aging process are not fully understood. In particular, how oxidation reactions contribute to the transformations of varietal aroma compounds.In the present study [3], we investigated the development of Riesling wine depending on a series of bottling conditions, which differed in the free SO2 level in wine (low—13 mg/L, medium—24 mg/L, high—36 mg/L), CO2 treatment of the headspace.
