Comparison of Satellite and UAV-Based Multispectral Imagery for Vineyard Variability Assessment [PDF]

Remote Sensing, 2019
In agriculture, remotely sensed data play a crucial role in providing valuable information on crop and soil status to perform effective management. Several spectral indices have proven to be valuable tools in describing crop spatial and temporal variability.

Satellite Monitoring of Italian Vineyards and Spatio-Temporal Variability Assessment

AgriEngineering
Sentinel-2 (S2) is widely considered a reliable satellite constellation for monitoring several crops, such as grapevine (Vitis vinifera L.). A large dataset of Italian vineyards randomly chosen was monitored with S2 from 2017 to 2022.

Reducing Within-Vineyard Spatial Variability Through Real-Time Variable-Rate Fertilization: A Case Study in the Conegliano Valdobbiadene Prosecco DOCG Region

AgriEngineering
Spatial variability in vine vigour and yield components is a major challenge for vineyard management and consistent grape quality, particularly in hilly landscapes.

Vineyard Spatial Structures of Key Soil, Vine and Fruit Metrics Are Hierarchically Associated

Australian Journal of Grape and Wine Research
Understanding vineyard spatial structure can help optimise grape production and ultimately wine quality by targeting the application of inputs through precision viticulture methods.

Vineyard variability: can we assess it using smart technologies?

IVES Technical Reviews, 2019
VitiCanopy is a smart-device computer application (app) that allows users to measure and interpret objective canopy architecture and its spatial distribution in the vineyard thus allowing for informed and targeted vineyard management decisions.

Variable Populations of Grapevine Virus T Are Present in Vineyards of Hungary [PDF]

Viruses, 2021
Grapevine virus T (GVT) is a recently described foveavirus, which was identified from a transcriptome of a Teroldego grapevine cultivar in 2017. Recently, we surveyed vineyards and rootstock plantations in Hungary using small RNA (sRNA) high-throughput sequencing (HTS), at a time when GVT had not yet been described.

Spatial Variability of Production and Quality in Table Grapes ‘Flame Seedless’ Growing on a Flat Terrain and Slope Site

Horticulturae, 2021
(1) Background: Precision agriculture has been used mostly to study spatial variability in vineyards for winemaking. Nevertheless, there is little available information on the impacts of its use on table grape vineyards under different slope conditions. (

A Smart Crop Water Stress Index-Based IoT Solution for Precision Irrigation of Wine Grape

Sensors, 2023
The Scholander-type pressure chamber to measure midday stem water potential (MSWP) has been widely used to schedule irrigation in commercial vineyards.

Making sense of a sense of place: precision viticulture approaches to the analysis of terroir at different scales

OENO One, 2020
Traditional ‘terroir zoning’ has largely relied on heuristic ‘expert’ opinion coupled with approaches to land classification based on thematic mapping to describe the influence of soil conditions and climate on wine composition.
