Geochemistry of Vrbničko Polje (Croatia) winegrowing site

Abstract

A multi-element pedo-geochemical survey was carried out in Vrbničko polje vineyards on the Krk Island, Croatia. This Mediterranean winegrowing site is famous by Žlahtina wine production. The objectives of this study are (i) to describe characteristics of the site related to climate, topography, geology, soil and geochemistry and (ii) to integrate data on soil quality using GIS which can be applied with management information systems Two soil profiles were excavated and examined, and dominant soil type was determined, as well as physical and chemical characteristics of soil. Topsoil (0-30 cm) and subsoil (30-60 cm) samples were collected from 26 locations inside the site. Total metal contents (Al, Ca, Cd, Co, Cr, Cu, Fe, Mg, Mn, Mo, Ni, P, Pb, S, V, Zn) were determined using ICP-OES after aqua regia extraction. A geospatial database was compiled in GIS, and after applying statistics and geostatistisc, the maps of trace metals distribution have been produced. Accumulation of copper in soil, determined in this research, is the most common effect of continuing fertilization and protection against diseases and pests in vineyards. High nickel and chromium concentrations seem to be of the geogenic origin. Associations of heavy metals with the selected soil properties explain the preferential feature of metal retention in soil.

Organic mulches improve vine vigour, yield and physiological response in a semi-arid region

Recycled organic mulch within the row in vineyard floor management has become an interesting ecological strategy to adapt the crop to climate change consequences in semi-arid regions.
This study aimed to assess the impact of three recycled organic mulches [straw (STR), grape pruning debris (GPD), and spent mushroom compost (SMC)] and two conventional soil management practices [herbicide (HERB) and under-row tillage (TILL)] on vegetative vigour (NDVI), production (kg/plant), and physiological parameters (δ13C in grapes and leaf gas exchange during four grapevine phenology stages). Additionally, temperature and water soil parameters were collected at three soil depths. Data was collected during the 2021 and 2022 grapevine growing seasons in La Rioja, Spain.

An analysis of wine geographical indications from the perspective of the theory of industrial organizations: what are the trade off?

From Porto and then through Bordeaux, Champagne and Bourgogne, wine geographical indications (gi) were the driving models for this form of protection of distinctive signs for collective use. Many studies present the benefits of recognizing a gi for a given region, the challenges of its implementation, as well as the possibilities of promoting territorial development.

Effets de l’application d’acide gibbérellique (GA3) sur la qualité de raisins et de vins produits en climat tropical au Nord-Est du Brésil

The honeydew moth Cryptoblabes gnidiella is the main problem for the wineries in the Northeast of the Brazil, because it attacks the bunch and reduces the quality of the grapes and the wines. In order to stretch out the bunch to facilitate the penetration of the insecticides, it was used gibberellic acid. Six treatments with different concentrations and different dates of application, and the control were compared.
