The ZOViSA Project (Viticultural zoning at farm scale) tests a new methodology for the viticultural zoning at farm scale integrating the classical pedological approach, the study of soil hydrological processes and the use of physically based agro-hydrological model. The project is conducted in two farms of southern Italy (Del Monte-Ponte(BN) and Quintodecimo-Mirabella Eclano (AV)) located in the Campania region and devoted to quality wines production (Aglianico and Falanghina DOC). One task of the project is to study the effects of soil-plant water status (e.g. soil water stress) on wine quality, through the use of simulation model SWAP. This latter allows estimating soil-plant water status in different crop phenological stages. Moreover, its use is fundamental to extend the approach from stand scale to farm scale, becoming also an important forecasting tool to support the farmer decision. In one site (Quintodecimo farm) the soil spatial distribution was recognized; then the experimental plots for monitoring the soil-plant water status were defined. Soil water variables (through TDR probes and tensiometers), crop development (biometric and physiological parameters) and climate variables (Temperature, radiation, rainfall, wind) were daily monitored. Afterwards, the model was calibrated and applied to estimate the crop water stress index. The results have been correlated to the crop physiological measurement (leaf gas exchange, chlorophyll-a fluorescence, leaf water potential, chlorophyll content, LAI measurement), grape bounches measurement (berry weight, sugar content, titrable acidity, etc.) and wine quality (aromatic response) in two different pedo-systems. Finally a preliminary "spatial application" of the model was carried out.

Abstract
The ZOViSA Project (Viticultural zoning at farm scale) tests a new methodology for the viticultural zoning at farm scale integrating the classical pedological approach, the study of soil hydrological processes and the use of physically based agro-hydrological model. The project is conducted in two farms of southern Italy (Del Monte-Ponte(BN) and Quintodecimo-Mirabella Eclano (AV)) located in the Campania region and devoted to quality wines production (Aglianico and Falanghina DOC). One task of the project is to study the effects of soil-plant water status (e.g. soil water stress) on wine quality, through the use of simulation model SWAP. This latter allows estimating soil-plant water status in different crop phenological stages. Moreover, its use is fundamental to extend the approach from stand scale to farm scale, becoming also an important forecasting tool to support the farmer decision. In one site (Quintodecimo farm) the soil spatial distribution was recognized; then the experimental plots for monitoring the soil-plant water status were defined. Soil water variables (through TDR probes and tensiometers), crop development (biometric and physiological parameters) and climate variables (Temperature, radiation, rainfall, wind) were daily monitored. Afterwards, the model was calibrated and applied to estimate the crop water stress index. The results have been correlated to the crop physiological measurement (leaf gas exchange, chlorophyll-a fluorescence, leaf water potential, chlorophyll content, LAI measurement), grape bounches measurement (berry weight, sugar content, titrable acidity, etc.) and wine quality (aromatic response) in two different pedo-systems.
