Spatial variability of the nutrient distribution in Jerez vineyard soils (Spain)

Abstract

From a fertility standpoint, the vine has to extract from the soil mineral substances necessary for its existence. However, the amount of certain available nutrients does not always correspond to a proportional increase in quality. Such is the case with nitrogen and organic matter and is in contrast to that of P and K, whose presence has a positive relation to quality. Most of the vintage wines come from vineyards located on calcium-rich soils, which have a complex effect on their quality. It is therefore necessary to characterize the soil for fertilizer practices in an objective way. The production area of Jerez has a notable environmental variability due to the landscape morphology (hills and plains), soil characteristics and the climate conditions due to its oceanic proximity. To assess the fertility of the soils of different vineyards and detect potential imbalances that may impede the growth of the vine and affect its production, a study has been made of distribution parameters such as O.M., P, K, Ca and Fe available in three plots representing the area of Jerez (Cadiz, Spain).The results have shown that OM and Fe presented a greater homogeneity in their concentration for the entire sample area with variances ranging between 0.09 and 0.82, and between 36 and 90, respectively. For the other nutrients analyzed, the variation between different points within the controlled sample plots was very important, noting interval concentrations of 5900 to 12480 ppm for Ca, from 8 to 158 ppm for P and 342 to 1698 ppm for K. The differences observed in the surface horizon remained in the deeper layers.

OPTIMIZING THE IDENTIFICATION OF NEW THIOLS AT TRACE LEVEL IN AGED RED WINES USING NEW OAK WOOD FUNCTIONALISATION STRATEGY

During bottle aging, many thiol compounds are involved in the expression of bouquet of great aged red wines according to the quality of the closure.1,2 Identifying thiol compounds in red wines is a challenging task due several drawbacks including, the complexity of the matrix, the low concentration of these impact compounds and the amount of wine needed.3,4
This work aims to develop a new strategy based on the functionalisation of oak wood organic extracts with H₂S, to produce new thiols, in order to mimic what can happen in red wine during bottle aging. Following this approach and through sensory analysis experiments, we demonstrated that the vanilla-like aroma of fresh oak wood was transformed into intense “meaty” nuances similar to those found in old but non oxidized red wines.

Geospatial technologies in spatially defined viticulture: case study of a vineyard with Agiorgitiko variety in Koutsi, Nemea, Greece

Geospatial technologies have significant contribution to viticulture, especially in small-scale vineyards, which require precise management. Geospatial data collected by modern technologies, such as Unmanned Aerial Vehicle (UAV) and satellite imagery, can be processed by modern software and easily be stored and transferred to GIS environments, highlighting important information about the health of vine plants, the yield of grapes and the wine, especially in wine-making varieties. The identification of field variability is very important, particularly for the production of high quality wine. Modern geospatial data management technologies are used to achieve an easy and effortless localization of the fields’ variability.
