Three proximal sensors to estimate texture, skeleton and soil water storage in vineyards

Abstract

Proximal sensors are becoming widely used in precision viticulture, due to the quick, easy and non-invasive identification of soil spatial variability. The apparent soil electrical conductivity (ECa) is the main parameter measured by sensors, which is correlated to many factors, like soil water content, salinity, clay content and mineralogy, rock fragments, bulk density, and porosity. This study compares three different sensors to delineate soil boundaries and estimate clay, skeleton content and available water (AWC) in a vineyard of the Chianti region (Central Italy). All three sensors produced ECa maps with similar pattern. Although the correlations between ECa, clay and skeleton content were usually moderate, the correlations between ECa and some important hydrological parameters, namely field capacity (FC), wilting point (WP) and available water capacity (AWC), was very high.

and overall plant vigor [1].

EFFECTS OF INDUCED SUNBURN DAMAGES ON WHITE WINE PROPERTIES

Climate change is a great challenge for the environment and affects the wine industry as well. Sunburn damage of sensitive grapes increase with severe heat periods. Besides significant loss of yield sunburn, modifies sensory properties of the wines and may cause climate-related off-flavours. To initiate sunburn in a controlled way, in 2021 sunburn was directly induced in the vineyard with the GrapeBurner device, exposing grapes of the varieties Riesling and Pinot Blanc with UV and IR radiation. This device was first assembled by Kai Müller of the university in Geisenheim and consists of a carriage with 6 UV/IR lamps. A 15 min irradiation was applied in early September at 60°Oe. Due to the colder season in 2021 the grapes were not harmed by previous sunburn damage.

Evaluation of consumer behaviour, acceptance and willingness to return of faulty wines

The analysis of consumer attitudes towards wine, especially towards wines perceived as faulty, is an aspect that requires more research than has been carried out so far [1]. This study aims to analyse consumer behaviour in situations involving the consumption of faulty wines and to assess the level of acceptance of such wines.
