Multivariate VaRs for operational risk capital computation: a vine structure approach
The Basel advanced measurement approach requires financial institutions to compute capital requirements on internal datasets. In this paper, we introduce a new methodology permitting capital requirements to take into account the embedded dependence structures of operational risks. The loss distributions are provided in a matrix of 56 cells. Constructing a vine architecture, which is a bivariate ...

Nondestructive measurement of grapevine leaf area by ground normalized difference vegetation index
Vine leaf area index has a great impact on berry quality. This study was conducted to determine whether vine leaf area index could be estimated, and mapped through normalized difference vegetation index (NDVI) ground-based measurements. The NDVI measurements were performed using a Greenseeker (N-Tech Industires, Ukiah, CA and Oklahoma State Univ., Stillwater), pointed sideways at the vertical ...

EVI vs NDVI: What’s the difference?
The wine industry has been using aerial imaging to measure vine vigor for decades. It is becoming more and more common for vineyard managers to use vigor maps to support their decision making in the field. These maps most often use the Normalized Difference Vegetation Index (NDVI) to measure vine vigor. NDVI has been the standard in the wine industry since the Mondavi Project in 1992. NDVI is a ...

How to Scout for Grapevine Leafroll Disease More Accurately and Efficiently Than Ever
In a previous post we discussed how Grapevine Leafroll disease affects grapevines but to quickly recap, Grapevine Leafroll Disease is one of the most common and persistent grapevine diseases; it can have devastating impacts on a vineyard, delaying fruit maturity and dramatically reducing fruit quality, pigmentation, vine vigor, and yield. With no cure for Leafroll, infected vines must be removed ...

Efficient Vineyard Irrigation Series #3: How to dynamically optimise irrigation scheduling
As climate change increases the cost and scarcity of water, as well as consumer concerns over environmental impact, efficient irrigation is fast becoming a key component of successful vineyard management. The need for efficiency is also growing with the increased frequency of extreme weather events (e.g. extreme heat, fluctuating rainfall, bushfires and droughts), which effect vine growth and ...

Tackle Vineyard Variability with Vine Health Predictions
Variability in vine vigour and grape composition makes it difficult for growers to meet uniform quality specifications from winemakers. As a result, growers often have the opportunity to make up to AU$2,155 per hectare for reducing variability. Vineyard variability is driven by climate, features of the land (e.g. topography and soil composition, including moisture content and nutrient ...

Linking Vine Growth Stages and Spraying Practices with AI Agritech
Pesticide/fungicide and liquid foliants and fertilisers are a crucial aspect of vineyard management. Sprays keep your vines disease-free, which helps you always produce top-quality fruit. By producing the very best grapes with every harvest, you'll maximise your earnings each time. Both amateur and veteran viticulturists still suffer from inefficient spraying practices, which is not only a ...

Arsenic present in the soil‐vine‐wine chain in vineyards situated in an old mining area in Trentino, Italy
The present study follows arsenic (As) transfer through the chain of soil‐vine‐leaves‐grapes‐wine to assess the possible risk of arsenic intake related to consuming grapes and wines produced in 10 vineyards located in a mining area rich in this element. The results are compared with date from 18 uncontaminated areas. In the soil, the content of As extracted with acqua regia and that available, ...

How to Help Grapevines Recover after a Difficult Frost Period
100% : this is the percentage of a vineyard that can be damaged by frost Cold snaps and frosts have hit many orchards and vineyards these last few weeks in France. High yield reduction will be expected due to these cold waves, occurring after weeks of heat and crop development. During dormancy, grapevines can support temperatures as low as -15°C. However, as soon as the vines bud, they ...

Effects of distillery vinasses on vineyard yield and quality in the D.O.C `Oltrepò Pavese Pinot Nero` – Lombardy, Italy
ABSTRACTIn a fifteen year old vineyard of Pinot Noir at a density of 5000 vines per hectares, located in the DOC zone Oltrepò Pavese, the influence of growing doses of distillery vinasses on vegetative growth, leaf mineral levels, grape yield and quality was tested in a four year period. Doses of vinasses were computed to apply 0 (test), 50, 100, 150 kg N ha+1. Vinasses doses were factorially ...

Precision viticulture technology a key to producing premium quality wines in changing climate [part 1]
Wines are made in the vineyard, which is especially true for premium quality wines. A study by Orley Ashenfelter from Princeton University revealed that the quality of the top Bordeaux vintages is predicted by the weather during the grape growing season. The price follows quality, and as every winegrower tends to maximize profits, it is crucial to work on producing premium quality wines while ...
