Characterization n the technoloy level of grapevine blocks in the sagrada familia county, Chile

Abstract

The technology level (NT) related to the management of grapevine blocks in the Sagrada Familia county, Chile, was estimated from technical-productive variables and using geomatic techniques. A SPOTMaps color mosaic was used for the identification and delimitation of grapevines blocks and GPS (global positioning system) equipment was used to support field work. The administrative and technical information associated with each vineyard and its grapevines blocks was collected by means of field surveys, whose variables and alternatives were later evaluated by experts related to the vine-growing sector. The spatial distribution pattern of NT was represented by maps. Most of the grapevines blocks (59%) have a medium level (NT2) of technological implementation, while the remaining area is divided equally between high and low levels (NT1 and NT3), with 20 and 21% respectively, which denotes a process of technological transition leading to improvement of vineyard productivity.
