Grapevine vigour is correlated with N-mineralization potential of soil from selected cool climate vineyards in Victoria, Australia

Abstract

Excess vigour has been a problem on fertile soils under high rainfall in many cool climate regions of Australia. High and low vigour blocks were selected in vineyards of the cool climate regions of King Valley, Yarra Valley and Mornington Peninsula, Victoria. Laboratory incubations were carried out on soil samples to measure their N-mineralization potential (N0). A strong relationship was observed between N0 and soil total N concentration across all sites. Vine internode length measured between flowering and fruit set could be used as a index of vine vigour and was well correlated with N0, but petiole N concentration was not a useful indicator of vigour at these sites. Sometimes high or low vigour may be due to other factors such soil water supply and soil depth, so that when interpreting a site’s potential for vigour all key soil and climatic variables should be considered.

Territoire, terroir et marché du vin à la production

Work aimed at understanding the relationship between a terroir, in the agronomic sense, and the physico-chemical characteristics of grapes or wine are numerous today, as evidenced by the program of this symposium. But for an economist, the central question remains to know how the terroir can intervene in the construction of the economic value of wine and in the differentiation of its prices. Is the terroir effect recognized by the end consumer or is it only an internal adjustment variable in the production systems? Through which indicators can this terroir effect be managed by the various operators in the sector? In the end, isn’t it better to invoke a “territorial effect” that the actors can build, and of which the terroir would be one of the possible components?
