VitiCanopy is a free application (App) for smartphones and tablet PCs that can be used as a simple and free alternative to traditional methods to measure canopy architecture parameters.
Use of proxy sensors to characterise spatial variability on agroforestry vineyards
Planting intercropped trees with grapevines is a practice that have recently been developed in French vineyards in order to bring beneficial effects to the parcel and its environment.
Gluconic acid as a tool for quality management in grapes
The concentration of gluconic acid can be used as an indicator of ripeness and sanity of grapes.
Precision viticulture: determination of the vigor’s spatial variability and its relation with vine response
In order to consider the potential interest of precision viticulture in the specific conditions of Uruguay, an experiment was performed in two plots of 1.8 hectares in a commercial vineyard planted with Tannat (Vitis vinifera L.) variety and trained to Vertical Shoot Positioning (VSP) trellis system.
