A predictive model of spatial Eca variability in the vineyard to support the monitoring of plant status

Abstract

In a vineyard, plant water status variability is strongly dependent on soil spatial variability, whose physical characteristics drive the processes involved in the soil water balance. More the soil and its characteristics vary in space (horizontally and vertically), more the productive and qualitative vine performances will be non-homogeneous. In this context, the proximal sensing of apparent soil Electrical Conductivity (ECa) and its monitoring during the growing season can help to understand the nature of spatial variability of vineyard, supporting both viticultural microzoning (identifying Homogeneous and functional Homogeneous Zones, HZs and fHZs) and field experiments. The aims of this contribution are: i) to show how the use of proximal sensing of ECa in the identification of HZs is important, (ii) to show the added value of ECa monitoring during the growing season in order to identify the fHZs, (iii) and to highlight its importance in the evaluation of the experimental field treatments results in vineyard. The study was carried out in two rainfed commercial vineyards located in the southern Italy (Campania Region) cultivated with Greco (white) and Aglianico (red) grapevine variety. Over 2020 and 2021 seasons, detailed soil and atmosphere parameters were recorded, in-vivo plant eco-physiological monitoring has been conducted, and vine status spatial variability monitored by means of UAV multispectral images. Apparent soil electric conductivity (ECa) was measured five times for each vineyard during the growing season 2021 by using the PROFILER EMP 400 electromagnetometer both in vertical and horizontal dipole mode. This instrument allows to simultaneously work with three frequencies (5000, 10000 and 15000 Hz) and explore different depth of sub-soil. The recorded data were processed in MATLAB and compared with other recorded variables within GIS environment. The results have shown how the ECa can be a carries of information to support viticultural microzoning and experimental field data analysis.

Effet terroir et arômes des muscats

L’étude porte sur trois terroirs du Roussillon, classés dans l’A.O.C. Muscat de Rivesaltes et concerne les 2 cépages de cette appellation : le muscat à petits grains et le muscat d’Alexandrie. Elle a pour objectif de connaître pour un terroir donné le meilleur choix de cépage.

Importance of the Terror Variability Map (TVM) in Precision viticulture (PV): choice of methodology for soil classification

The Precision Viticulture (PV) is defined “as a management system that is information and technology based, is site specific and uses one or more of the following sources of data: soils, vigour, nutrients, pests, moisture, and yield among others, for optimum profitability, sustainability, and protection of the environment” (OIV, 2018, in process). The elements mentioned in the definition are an important part of the terroir components. The terroir is a tool In Viticulture, it is the analysis and study unit, and the variability of a certain situation can be due to any difference in every element or property of each factor that constitutes it, including the management.The soil and its management are those that bring the most variability to terroir.

Protection of grapevines from red blotch by understanding mechanistic basis of its infection

Currently, grapevine is host to a large number of pathogenic agents, including 65 viruses, five viroids and eight phytoplasmas. Needless to say, these pathogens, especially viruses responsible for several ‘infectious degeneration’ or ‘decline’ cause great distress to wine makers and grape growers, let alone the large economic losses incurred by the wine industry. A recent addition to this wide repertoire of grapevine viruses is a new viral disease known as Red Blotch in viticulture parlance. Its causal organism, Grapevine red blotch associated virus (GRBaV), discovered in 2008 is a newly identified virus of grapevines and a putative member of a new genus within the family Geminiviridae.
