VRDI - Variable Rate Drip Irrigation in Vineyards

Advances in Animal Biosciences, 2017
Vineyards worldwide are subjected to spatial variability, which can be exhibited in both low and high yield areas. We developed a variable rate drip irrigation (VRDI) concept to reduce such variability. The VRDI system divides the vineyard into 30×30-meter irrigation zones, enabling individual irrigation of each zone according to normalized difference ...

Soil spatial variability in the vineyards of La Rioja PDOC (Spain)

International Journal of Environmental Studies, 2021
Characterisation of soil variables illuminates the influence of the soil on wine quality and other features. The patterns and spatial variability of soil reaction and the content of organic matter, clay, and carbonates of vineyard soils have been investigated throughout the Rioja PDOC area.

Studying spatial and temporal variability of a ‘Barbera’ vineyard with traditional and precision approaches

Acta Horticulturae, 2020
Land is variable and vine performances reflect such variability. Precision viticulture, based on remote sensing and variable rate technologies, is a valuable tool for its description and management. Because vineyard monitoring can be accomplished through different platforms, a wide array of solutions is now available combining different spatial and ...

Real-Time Variable Rate Spraying in Orchards and Vineyards: A Review

Journal of The Institution of Engineers (India): Series A, 2018
Effective and efficient use of pesticides in the orchards is of concern since many years. With the conventional constant rate sprayers, equal dose of pesticide is applied to each tree. Since, there is great variation in size and shape of each tree in the orchard, trees gets either oversprayed or undersprayed. Real-time variable rate spraying technology

Spatial variability in Ontario Riesling vineyards. II. Berry composition

Canadian Journal of Plant Science, 2020
Spatial variability of berry composition was studied over a 3-yr period in 10 Riesling vineyards in the Niagara Peninsula in Ontario. Vineyards were delineated using global positioning systems (GPS), and 75–80 sentinel vines were georeferenced within a sampling grid for data collection.

Compositions and chemical variability of grape pomaces from French vineyard

Industrial Crops and Products, 2013
Compositions of 8 pomace samples originating from red and white winemaking from different areas of production of French vineyard were characterized (Alsace, Bordeaux, Bourgogne, Champagne, Languedoc, Val de Loire and Provence). Large variabilities were observed depending on cultivar and grape varieties: pomace samples contained 3-6% w/w of oil and 20 ...

Using Grape Leaf Reflectance for Spatially Variable Vineyard Management

2004, Ottawa, Canada August 1 - 4, 2004, 2004
Spectral reflectance of grape leaves was measured over the range of 450-2400 nm. Reflectance spectra of leaves from healthy and phylloxera-infested vines were compared and significant differences were noted in the visible part of the spectrum. A Green-Red Ratio (GRR) was evaluated to distinguish between the two groups of leaves.
