Vine response to compost addition on a sandy-loam soil in the north-east of italy. Effects on root system, vegetative growth, yield and grape quality of Cabernet-Sauvignon cv

Abstract

In this study two different compost types and two application methods were studied over 5 years (2009-2013) on mature Cabernet Sauvignon vines grown in a commercial vineyard in the AOC Piave area, northeastern Italy. The treatments compared were: IM: inter-row application of compost from cattle manure, at a rate of 4 t/ha/y fresh weight (fw); IW: inter-row application of compost from vineyard pruning waste, at 4 t/ha/y (fw); UW: under-row application of compost from vineyard pruning waste, at 4 t/ha/y (fw); C: control with no amendment/fertilization. Effects on soil characteristics and on vine performances, including root density and distribution, were assessed. IW treatment showed the best overall performance, displaying well-balanced root/shoot growth, increased yield, and satisfactory grape quality. Inter-row addition of compost from cattle manure (IM) and localized addition of compost from pruning wastes (UW) stimulated ether high vegetative growth or high root development and in both cases, a reduction in fruit quality was observed, likely due to competition between vegetative organs (shoots or roots) and the fruit.

L’essor des produits “No-Low” : nouveaux défis pour l’étiquetage et la réglementation

In recent years, “no-low” products seem to become a new worldwide trend. It appears to be a possible answer to the well-known context of climate change, the decline in wine consumption, and the wellness/health trend (“free from” claims, vegan, and so on…) That consumers are looking for. The aim of this study is to provide an overview of the “no-low” products sold in the french market (but not only french products), focusing on the labelling, packaging, and sales presentation of these products.

The performance of grapevines on identified terroirs in Stellenbosch, South Africa

A terroir can be defined as a natural unit that is characterised by a specific agricultural potential, which is imparted by natural environmental features, and is reflected in the characteristics of the final product.

On the meaning of looking for terroir perceptions in blind tastings

If one considers as “physical or sensory attributes” of a wine its concentrations of alcohol and of other substances, it can be stated that another class of attributes exists

Use of computational modelling for selecting adsorbents for improved fining of wine

The occurrence of faults and taints in wine, such as those caused by microbial spoilage or various taints, have resulted in significant financial losses to wine producers. The wine industry commits significant financial resources towards fining and taint removal processes each year. Fining involves the addition of one or more adsorptive substrates to juice or wine to bind certain components, thus reducing their concentration [1]. However, these processes are often not selective and can also remove desirable flavour and aroma compounds.
