The objective of this work was to test the extrapolation of soil-landscape relationships in a reference area (RA) to a topographic map (scale 1:50,000), using digital soil mapping (DSM), and to compare these results to those obtained in similar studies previously conducted in Brazil. A soil survey in a 10 km2 RA, using conventional mapping techniques (scale 1:10,000), was made in order to map a 678 km2 physiographically similar area (scale 1:50,000) using DSM. The decision tree technique was employed to build a predictive extrapolation model based on soil classes and eight terrain attributes in the RA. The validation of DSM by application of field observation points resulted in a 66.1% global accuracy and in 0.36 kappa index. The most representative soils in the area were correctly predicted, whereas the less representative and less frequent soils in the landscape (and consequently with reduced sampling) had their prediction compromised. The RA proportion, which equals 1.5% of the total area, is a limiting factor in the formulation of soil-landscape relationships to precisely represent the mapped area by DSM. |

Wine production is a recent economical activity on tropical regions. In Brazil, tropical wines production started on Sub-Middle São Francisco River Valley Region in the early 1980 years. In the following years, other tropical countries such as Venezuela, Thailand and India have invested in the wine industry. All wine grape cultivars used in the tropical zones are introduced from the traditional temperate winegrowing regions. There are a small number of wine grape cultivars whose cultivation is consolidated in tropical environments, such as ?Syrah? and ?Chenin Blanc?, which possess good adaptation and present a great potential of wine quality. Wine grape cultivars evaluation and selection is one of the important priorities in order to diversify the quality wine production in the tropics. The environmental diversity of tropical zones in comparison with the original regions of wine grape cultivars, all of them from temperate climates, requires detailed evaluation and specific cultural practice adjustments to obtain convenient production from each cultivar and for each tropical environment. Climatic factors as winter absence, temperature changes and rain variations throughout the year change the physiological behavior of vines, offering different grapes and wine qualities at different seasons. In this paper are discussed questions inherent to the screening criteria and evaluation methodology to select wine grape cultivars to produce quality wines in tropical regions. Results obtained at the Sub-Middle São Francisco River Valley are presented. MenosWine production is a recent economical activity on tropical regions.
