Effects of different organic amendments on soil, vine, grape and wine, in a long-term field experiment in Chinon vineyard (France)

Abstract

In a long-term experiment carried out in Chinon vineyard (37, France) during 23 years, the effects of several organic amendments were studied on soil, vine, grapes and wine. Four main treatments were compared on a calcareous sandy soil: control without organic amendment, dry crushed pruning wood at 2.1.t-1.ha-1.year-1 (D1), cow manure at 10 t-1. ha-1.year-1 (D1) and cow manure applied at 20 t-1.ha-1.year-1 (D2). D1 levels were calculated to fill the annual humus losses by mineralization. During the experiment, the organic matter content of topsoil (0-30 cm) decreased from 13.9 g.kg-1 to 11.1 g.kg-1 in control. Other treatments maintained or strongly increased the organic matter content of soil, according to applied organic manure levels (21.9 g.kg-1 measured in 1998, in cow manure D2 treatment). Soil CEC, soil moisture at field capacity, and amounts of available P, K and Mg were significantly improved in different organic treatments.

The weight of pruning wood and grape yield were not modified in D1 organic amendments, but were significantly lower in D2 cow manure. Nitrogen rate in leaves, as well as in berries and in wine, was higher in this last treatment. Also, in D2 cow manure grape composition was unfavourably modified. Consequently, alcoholic rate, colour intensity, anthocyanins and phenolic compounds of wine were lower, but total acidity and pH were higher than in other treatments.

Quali cantine perle strade del vino

Tutte le cantine possono aprirsi al pubblico? Evidentemente si, nessuno può impedire ad un produttore di accogliere i turisti. Tutte le cantine possono far parte delle Strade del vino? No, perché la Strada del vino mette in gioco la reputazione della denominazione di origine alla quale è legata e le possibilità di sviluppo economico di un intero territorio.

The Baco Blanc, the Armagnac hybrid variety adapted to the viticultural challenges of tomorrow

Today in the wine industry, a lot of alternatives are available for reducing phytosanitary inputs. Among these, prophylaxis, the use of biocontrol products and the deployment of pathogen-resistant vines are the most promising. eugenol (2-methoxy-4-(2-propenyl)-phenol), a molecule with recognised antifungal properties, can contribute to the last two alternatives. This molecule has been identified as an endogenous compound in the baco blanc hybrid variety used in armagnac pdo, which is at least tolerant to botrytis cinerea.

Influence of different Lachancea thermotolerans strains in wine acidity

Wine acidity is a parameter of great importance that influences different quality factors of the product such as biological stability or organoleptic characteristics. In the current context of climate change, which gives rise to wines with higher levels of ethanol and lower acidity, the biological acidification with yeast species such as Lachancea thermotolerans could be a solution.
In this work, the effect of the inoculation of different L. thermotolerans on the acidity of wine was studied.
