Sustainable models of cultivation of the Greek grape: efficiency of use of resources and application of indicators of the 'Footprint family'
The project is part of research on the sustainable management of the vine agrosystem in the context of climate change, with reference to the safeguarding of natural resources and correct management of crop factors.One of the problems encountered in some areas, in particular that of Greco di Tufo, is the low profitability that triggers phenomena of cultivation reconversion and merging of small / medium-sized companies with leading companies with the loss of historical-cultural identity. There emerges the need to increase the production, keeping the quality of grapes and wines high. The general objective is to identify a varietal model of canopy and soil management for the expression of the potential of Greco, which pursues the achievement of a good vegetative balance. production, the increase in company profitability and environmental sustainability (according to the Footprint Family approach). The general objective will be achieved with a multidisciplinary approach based on three activities (A): A1. Verification of the effect of the conversion of the pruning method on the capacity to use resources (retrospective analyzes) A2. Analysis of the effect of the training systemA3. Analysis of the effect of soil management
The study is carried out on a Greek grape plant, converted 7 years ago from the traditional pruning method to the Simonit & Sirch method (Simonit 2014 Manual of vine pruning Ed IA; Sun et al 2008 Am J Bot 95: 1498-1505). The investigations are based on the evaluation of the hydraulic architecture of plants with retrospective techniques of dendro-anatomy and stable isotopes to evaluate the variation in the efficiency of use of resources after conversion. As part of three different land management: sown, natural and worked. The site is monitored through a Davis weather station and six soil water content measurement points at three different depths
