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.

Influence of protein stabilization with aspergillopepsin I on wine aroma composition

The protein haze formation in white and rosé wines during storage, shipping and commercialization has always been an important issue for winemakers. Among the various solutions industrially proposed, the use of bentonite is certainly the most widespread. However, the harmful effects of this treatment are known either in terms of wine volume loss and wine flavour and aroma.
