By using a decision support system for disease management – that can process environmental data, together with vineyard characteristics, and growers’ past activities – winegrowers get an alert on possible pest hazards on a particular vineyard area upfront, along with advice on how to handle the situation. ...
Soil moisture is critical to the growth of the vine and monitoring can help take actions to improve grape quality and yield. With the increasing scarcity of water and cost of water, optimizing irrigation timing, frequency, quantity and location is key for vineyard management. Current Best Practice Current best practice, a grower would install ground soil moisture sensors in multiple ...

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 ...
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. ...
Bitwise Agronomy, an emerging agritech company based in Tasmania, has just launched GreenView: a smart imaging and data-collection application that helps vineyard owners assess their vines' conditions and make crop management decisions at a touch of a button. ...
The transition to organic wine grape growing can be seen as a high-risk process, and growers often wonder if positive results published by academic researchers will actually translate to their bottom lines once implemented in their vineyards. In order to address the concerns about the perceived gap between research and economic success, telling stories which share the lessons learned by people ...
Send in the Sheep! Sheep in the vines – what a pleasant view driving in to Baileys Vineyard in Glenrowan, Victoria. It set me to thinking if this and other organic vineyard management practices could be implemented in all vineyards whether they be organically certified or not. Does sheep grazing provide a sustainable and practical alternative to chemicals or do they create more issues ...
Healthy soil makes for optimal crops and today, there are seemingly countless ways to monitor and test soil health, from physical samples to sap flow and moisture monitoring, aerial imagery, and beyond. Here are some of the most recent developments, as well as how technologies are being used in the field. Fruition Sciences Precision agriculture company Fruition Sciences takes data measurements ...
Last November, Arable participated in Silicon Valley Argentina in Rosario, a forum co-organized with Fundación CEDEF, Chacra Media Group, and Silicon Valley Forum. We’ve been to a number of ag shows in the US, and have never seen anything that compares to the caliber of this event. The best part was its forward-thinking focus on ‘the next generation of ag’: It was more ...

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 ...

Received for publication April 19, 2008. Organic viticulture is an important part of the European Union organic farming sector, and, according to the most recent surveys, 1.5% of European Union wine originates from organic farms, with an upward trend. This paper describes an environmental impact of an organic viticulture indicator (EIOVI) that can be reliably used in the management of organic ...
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 ...
