Impact of organic inputs on soil biodiversity in vineyard systems. A monitoring approach during 20 years

Abstract

Conventional vineyard practices have lead in many environmental disturbances as erosion, soil compaction, loss of organic matter and soil biodiversity, water contamination… Therefore, there is an increasing interest to develop sustainable viticulture in the famous Champagne vineyard for 20 years: a program called “VITI 2000” has been developed since 1986 by CIVC (Inter-professional Committee of Champagne Wine) in collaboration with scientists. The aims are i) to assess the impact of viticultural practices on soil functioning, environmental properties and wine quality, ii) to advice progressively sustainable practices to winegrowers. One strength of this program is to allow a long term field experiment: earthworm communities, microbial biomass, soil and vine parameters were followed during 25 years in 19 plots representing 66 treatments to test the impact of pesticides applications (nematicides, fungicides, herbicides), or organic matter inputs, or vine management (organic vs conventional vs integrated). This program ended in a huge data collection e.g. the data table of earthworm communities (species, body mass, sexual stage) presents more than 39 000 lines. A database, compatible to others soil fauna databases developed by the laboratory EcoBio (University Rennes 1), has been developed. First results indicate that i) grass strip between the vine rows and compost quickly stimulate biological soil processes, while dried organic matter inputs have a slow positive impact, ii) fungicides containing copper alter in the same pattern earthworms and microorganisms, iii) integrated management could be as positive as organic practices. Statistical treatments are still going on and further results will be discussed.

Ugni blanc berry and wine composition impacted by thirteen rootstocks

The Cognac region is expanding, driven by the success of its renowned brandy and the demand for high grape yields to ensure a steady supply of base wine for distillation. Ugni blanc, the most widely planted grape variety, relies on rootstocks for soil and climate adaptation, providing essential nutrient supplies to the scion. Understanding the impact of rootstocks on key berry components, such as sugars and nitrogen compounds, is crucial. These compounds serve as primary precursors for the production of fermentative aroma metabolites, which, in turn, act as quality indicators for eau-de-vie.

Discrimination of monovarietal Italian red wines using derivative voltammetry

Identification of specific analytical fingerprints associated to grape variety, origin, or vintage is of great interest for wine producers, regulatory agencies, and consumers. However, assessing such varietal fingerprint is complex, time consuming, and requires expensive analytical techniques. Voltammetry is a fast, cheap, and user-friendly analytical tool that has been used to investigate and measure wine phenolics.

Post-spring frost canopy development and fruit composition in cv. Barbera grapevines

One of the effects of warming trends is the advance of budburst, increasing the frequency of spring frost-related damage. In April 2021, a severe frost event affected central and northern italian viticulture. In a cv. Barbera vineyard located in the Colli Piacentini wine district, after such occurrence, vines were tracked and growth of primary bud shoots (PBS), secondary bud shoots (SBS), and suckers (SK) was monitored, as well as their fruitfulness and fruit composition. Vine performances were then compared to those of the previous year, when no post-budburst freezing temperatures occurred. The goal of the study was to evaluate the efficacy of SBS in restoring yield loss due to PBS injuries and analyze respective contribution to fruit composition.
