| In the traditional Pedology conception, tropical soils refer to those which have been developed in environmental and mainly climatic extreme conditions with copious precipitations and high temperatures. However, this analysis focused on soils that are formed in a tropical geographic context but their climatic conditions, through a suitable management, are advantageous to vine-growing in order to produce quality wines. With this view, bio-geographic criteria that allows us to survey the potentially important zone to the development of a specialized viticulture are established; to sum up, the analysis is restricted to those tropical regions that are not excessive rainy (< 750 mm) and warm: isotherm of 20º C in January (N) and July (S) and with an average diurnal amplitude higher than the annual one. In these limits, important regions in Sub-Saharan Africa, such as the Sahel, the Eastern zone and Southwest of Madagascar, the Northwest of India, a great deal of Australia and South America (NE of Brazil) and Central America are included. In this zone and in spite of that the pluviometry has been surveyed, the soils formation processes are really active (alteration and weathering, salts and gels and silica mobilization, hidromorphisme, vertisolization, planosoliztion etc) and the pedological variability promoted by them is very important (Entisols, Inceptisols, Vertisols, Alfisols, Untisols and locally Oxisols, Mollisols, Andisols and Aridisols ), mainly according to the rock type (lithology ) and to the landscape ( Geo-morphology ). In this context, the main soils in the tropical zone that have a vocation for viticulture are described and compared with similar and important ones in the traditional viticulture. Likewise, their limiting properties are commented and related to their management possibilities. | |
