The soil biodiversity as a support to environmental sustainability in vineyard

Abstract

The environmental biodiversity is important to guarantee essential services to the living communities, its richness is a symptom of a minor disturbance and improves he environment biological quality. The edaphic communities, in particular, ensure plant development in natural habitats and cultivated land although the human intervention may disturbs their stability and equilibrium. The assessment of soil biodiversity, quite complex for the huge number of edaphic species and the limited availability of simple and inexpensive methods, is useful for estimating soil biological quality and the impact of the human activity. The QBS-ar method assess biodiversity and biological quality of the soil evaluating the microarthropods’ level of adaptation to the soil life. By applying this method, a study was carried out to assess soil biodiversity in vineyards, observe the variability between plots and estimate the influence of soil physical and chemical characteristics on edaphic community.

The study started in 2015 in the Barolo winegrowing area (north-west Italy). The area is characterized by soil homogeneity but wide geospatial heterogeneity, which is why the commercial vineyards under observation were also characterized by this point of view. For each vineyard pedological survey were executed analysing the soil profile, the chemical and physical composition, the soil hydrological constants and the microarthopods community.

In Barolo area, the abundance of individuals and the QBS-ar index showed diversity among the vineyards but were not affected by the weather variability or geospatial variability. It emerged a possible correlation with the physical characteristics of the soil, such as density and porosity; these properties are dependent on the soil texture but they also vary depending on the management practices. The index reveals a good potential for rapid assessment of elements linked to environmental quality although many aspects still remain to be defined including, for example, the relationships with crop management.

Towards the understanding of wine distillation in the production of brandy de Jerez. Chemical and sensory characterization of two distillation methods: continuous and batch distillation

Brandy de Jerez (BJ) is a spirit drink made exclusively from spirits and wine distillates and is characterized by the use of casks for aging that previously contained Sherries. The quality and sensory complexity of BJ depend on the raw materials and some factors: grape variety, conditions during processing the wine and its distillation, as well as the aging in the cask. Therefore, the original compounds of the grapes from which it comes are of great interest being in most cases the Airén variety. Their relationship with the quality of the musts and the wines obtained from them has been studied (1) and varies each year of harvest depending on the weather conditions (2).

Étude de la composante climatique du terroir viticole en Val de Loire : relation avec les facteurs physiques du milieu

The research carried out by the URVV of the INRA center in Angers aims to develop a methodology for the integrated characterization of the natural factors of viticultural terroirs, representative of the operating conditions of the vine and the sensory differences of the wines. In this context, the concept of Basic Terroir Unit (UTB) has been developed. The UTB represents a viticultural surface of variable geographical extension, defined as the association in a given place of a geological, pedological and landscape component, Morlat (1989), Riou et al. (1995).

La perception des terroirs du vignoble des Coteaux du Layon

On peut être surpris de l’existence d’un vignoble de vins liquoreux, le vignoble des Coteaux du Layon, dans une zone septentrionale à la limite Nord de la culture de qualité de la vigne et ce d’autant plus que le cépage de ce vignoble, le Chenin ou Pineau de la Loire, est un cépage semi tardif. La première explication est à rechercher au niveau des facteurs naturels (données climatiques et géopédologiques) permettant la réalisation de ce type de produit. Il est nécessaire de souligner ici l’importance de chaque paramètre du terroir pris dans im sens large (géopédologique et climatique) et que toute variation de l’un d’entre eux, même non perceptible en première analyse à l’homme, peut avoir des incidences déterminantes sur la qualité des vins.
