Satellite imagery : a tool for large scale vineyard management

Abstract

Remote sensing, using Near Infra Red wavelength, can characterize within-vineyard variability using vegetation index. Between 2007 and 2009, a study was led on the vineyards of a cooperative winery, in Fitou area (France) aiming at characterizing vineyard oenological potential. A vegetation index, green leaf cover, developed on crops (wheat, rice, corn…) was implemented on vineyards.
In a first stage, it was proved that the use of 2m/pixel resolution gave the same precision of field variability mapping than a 0,50 m/pixel resolution, which made possible the use of satellite datas, covering a 57 600 or 302 500 ha zone (respectively 24 km x 24 km or 55 km x 55km). Then a heterogeneity index, adapted from Pringle’s opportunity could be calculated for each vine, which can be characterized by an average leaf cover index (a “vigor” index), and an heterogeneity index. Detection of high levels of bare soil in a vine can also be identified automatically.
Based on these indexes, each vine can be characterized and gathered with other vines with the same characteristics (homogeneous vines with either low or high vigour, heterogeneous vines, abnormal vines with excessive bare soil….). According to such a classification realized just before veraison, the winery could select bins corresponding to each quality of vines. Separate vinifications proved sensorial differences on wines: homogeneous vines would give wines with intense jammy and spicy flavours, interesting body in mouth, and smooth tannins, whereas heterogeneous vines tended to produce wines with more red fruit and grassy aromas, and coarser tannins. These differences are consistent from year to year. This selection method is used on 50 % of carignan vines by the winery, which cannot be visited by its technical staff.

Leaf elemental composition in a replicated hybrid grape progeny grown in distinct climates

The elemental composition (the ionome) of grape leaves is an important indicator of nutritional health, but its genetic architecture has received limited scientific attention. In this study, we analyzed the leaf ionome of 131 interspecific F1 hybrid progeny from a Vitis rupestris (♀) X Vitis riparia (♂) cross. The progeny were replicated in New York, South Dakota, Southwest Missouri ad Central Missouri, and the concentration of 20 elements were measured in their leaves at three different phenological stages during the growing season. In leaves collected at the apical node at anthesis, elemental concentrations correlated in a consistent manner (p < 0.05) across all four geographic locations. In subsequent phenological stages, elemental ratios in the apical-node leaves remained consistent across the South Dakota and New York sites, but not across the Missouri sites. In leaves collected at the basal and middle nodes, correlations varied greatly across all locations.

Greek and Cypriot grape varieties as a sustainable solution to mitigate climate change

Aim: The aim of this report is to present evidence on the potential of Greek and Cypriot grape varieties to serve as a sustainable solution to mitigate climate change.

Methods and Results: The work provides a review of recent works involving Greek and Cypriot varieties’ performance under high temperatures and increased dryness.

EFFECTS OF BIODYNAMIC VINEYARD MANAGEMENT ON GRAPE RIPENING MECHANISMS

Biodynamic agriculture, founded in 1924 by Rudolph Steiner, is a form of organic agriculture. Through a holistic approach, biodynamic agriculture seeks to preserve the diversity of agriculture and the existing interactions between the mineral world and the different components of the organic world. Biodynamic grape production involves the use of composts, herbal teas and mineral preparations such as 500, 501 and CBMT.
Several scientific studies have provided evidence on the effects of biodynamic farming on the soil, the plant and the wine. Numerous empirical opinions of wine growers support the existence of differences brought by such a management.

Chemical and microbiological evaluation of Ribeiro wines (NW Spain)

Wine produced under Designation of Origin (DOP) Ribeiro, the oldest DOP in Galicia (NW Spain), are elaborated using local grape cultivars, grown at the valleys of Miño, Avia and Arnoia rivers. The landscape formed by slopes and terraces and the peculiar climate of continental character, softened by the proximity of Atlantic Ocean, make it an area of excellent aptitude for vine cultivation. In addition, small-scale farming and the use of traditional techniques for vineyard management provide a great diversity to Ribeiro wines. This study presents the evaluation of red and white wines (bottled or bulk wines) from DOP Ribeiro, produced between years 2018-2022.

Challenges and opportunities for increasing organic carbon in vineyard soils: perspectives of extension specialists

Context description and research question: an increasing number of farmers are considering the impact of conservation practices on soil health to guide sustainable management of vineyards. Understanding impacts of soil management on soil organic carbon (SOC) is one lever for adoption of agroecological practice with potential to help maintain or improve soil health while building SOC stocks to mitigate climate change (Amelung et al., 2020).
