Are precision agriculture tools and methods relevant at the whole vineyard scale ?

Résumé

Precision viticulture has been applied to date mainly at the field level, for which the ability of high resolution data to match within-field variability has been already shown. However, to be fully operational, it should also be applicable at the whole-vineyard scale. The aim of this study was to analyze whether it is possible to use precision viticulture tools to define meaningful management zones at the whole-vineyard scale. Experiments were carried out in year 2008 on 90 ha planted of cv. Tempranillo from a vineyard with a total area of 140 ha in Spain. A three-level classification was established at both scales using NDVI, elevation and soil apparent conductivity data. The agronomic significance of these classes was tested comparing the vegetative growth, yield, carbon discrimination isotopic ratio and berry quality observed at each class. The analysis of high resolution information has been proved to be relevant in order to define whole vineyard classes with agronomic implications, the spatial variability of the vineyard being structured.
