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.

Terroir e DOC: riflessi produttivi e commercial

Da dove scaturisce tutto l’interesse attuale per il terroir? Si provi, per dare risposta a questo quesito, ad immaginare il vino avulso dalla sua dimensione territoriale. Cosa si otterrebbe? Un vino bianco, un vino rosso o quant’altro, ma comunque un prodotto privo di conno­tazione geografica, di premesse storiche, di radici tradizionali, di potere evocativo, di iden­tità e di personalità.

Behaviour of two training systems for mechanical pruning combined with different nitrogen fertilizations on cv. Colombard

Today winegrowers involved in mechanical winter pruning are applying this viticultural technique on two main training systems, the free cordon, appearing to be the more efficient, and the trellised vertical shoot positioning (VSP) system. The main reasons for maintaining the trellis are generally due to common habits in vineyard management, risk of wind damage for the shoots, or risk of decrease in photosynthesis potential. The aim of the study was to assess the effects of the two training systems on vine. In addition, different nitrogen fertilization levels were applied on the two systems to evaluate the best combination to achieve yield and grape quality.

Methyl Jasmonate Versus Nano-Methyl Jasmonate: Effect On The Stilbene Content In Monastrell Variety

Stilbenes, a kind of non-flavonoid phenolic compounds, have been reported to be responsible for various beneficial effects. Their biological properties include antibacterial and antifungal effects, as well as cardioprotective, neuroprotective and anticancer actions (Guerrero et al. 2009).Several strategies can be used to increase stilbene content in grapes and one of them could be the use of elicitors such as methyl jasmonate. The use of this elicitor has been proven to be efficient in the production of secondary metabolites which increases the quality of wines, but its use also has some drawbacks such as its low water solubility, high volatility, and its expensive cost (Gil-Muñoz et al. 2021).
