| Sumario: | Adequate information from the agricultural suitability of the land for viticulture is of great importance to expansion of activity in wine producing regions, such as in the state of Santa Catarina State, Brazil. In this context, this study aimed to adapt the system for evaluating agricultural potential of the land (SAAAT) favored by Ramalho Filho e Beek (1995) for the culture of the vine produced in altitude region in the state of Santa Catarina. To this end the SAAAT was modified from the requirements and form of crop management, and proposed the merger, removal, adjustment and parameters used in SAAAT updates. The limiting factors considered were: a) Topography; b) Fertility; c) Excess water or oxygen deficiency; d) susceptibility to erosion; e) Impediment to mechanization; and f) Soil effective depth. These parameters resulted bibliography data collection and were related to them five degrees of limitation: null; light; medium; forte and very strong. Agricultural suitability classes (Good, Regular, Restricted and unfit) resulted from the interaction of agricultural conditions and management level of winemakers and in the end, was adapted the fitness guide frame. The adaptation of SAAAT for the vine to the specific altitude conditions in the state of Santa Catarina incorporates and adjusts sites relevant to the grape production system. It is becoming important tool for decision making in the implementation of new vineyards, contributing to possible expansion of this activity in the region. |
