Precision viticulture: using on-board sensors to map vine variability and characterize vine trajectories

Precision viticulture consists in using ICT (Information and Communication Technology) to implement more specific and better targeted technical vine practices. With proxy-detection, precision viticulture mobilizes on-board sensors, computers, and GNSS positioning. Three sensors were embedded on a tractor and tested on a plot with three champagne grape varieties. This plot is located at the Plumecoq […]

Soil electrical resistivity measurement: from terroir characterization to within-field crop inputs management

Soil Electrical Resistivity measurement is a zoning tool used by soil scientists and agronomists in viticulture. Indeed, the measure enables to optimize pedological surveys (position and number of soil sampling) to obtain a very precise final soil map. Since 2007, Tutiac Winegrowers (Vignerons de Tutiac, Bordeaux) have decided to map all their vineyards (over 4000 […]

Terroir effects on the response of Tempranillo grapevines to irrigation in four locations of Spain: grape and must composition

This work discusses the effects of soil and weather conditions on the grape composition of cv. Tempranillo in four different locations of Spain, during the 2008-2011 seasons. In all locations vines were pruned to a bilateral cordon, trained to VSP and under similar cultural practices. In three locations (Requena-east, Badajoz-west and Valladolid-northwest) a pre-veraison deficit […]

Corvina and Corvinone grape berries grown in different areas and their aptitude to postharvest dehydration

The Valpolicella area (Veneto Region, Italy) is famous for its high quality wines: Amarone and Recioto, both obtained from partial post-harvest dehydrated red grapes. The main cultivars used for these wines are Corvina and Corvinone. In this region hundreds of years ago a particular wine making process was developed to dehydrate the grape after the […]

Viticultural practices: past, present and future

Practices in viticulture have greatly evolved in the last five decades. There were three objectives: improvement in the quality of the products, reduction in the production costs through mechanization, and protection of the environment. In terms of soil management, the combination of different techniques such as soil tillage, chemical weeding and cover-cropping, allowed to reach […]

Monitoring arthropods diversity in the “Costières de Nîmes” viticulture landscape

Biodiversity loss in agrosystems is partly due to landscape simplification (field enlargement, hedgerows removal…) that led to a loss of heterogeneity of the overall landscape. The aim of this study is to compare biodiversity of different habitats and landscape configurations in order to target strategic conservation actions and their locations in viticulture landscapes to improve […]
