That differentiate the soil of the major producing regions of the world wine. The study was conducted in the regions of west and mountain through Santa Catarina, covering over 80 % of the properties where descriptions and collections of 38 modal profiles and vineyards spread over 45 farms were carried out. The objectives were: a) To characterize the distribution and interaction of soil formation factors and chemical weathering rates; b) evaluate and quantify the carbon, humic fractions in the profiles and ?13C in surface horizons of Cambisols; c) To characterize physical and chemically soils of the vineyards; d) To evaluate the agricultural potential through different methods, with subsequent adaptation of the System for Agricultural Assessment of land for the grape culture in addition to formulating a proposal for zoning for the wine industry of the state. The results indicate that pedogenetic soil was strongly influenced by the source material, weather and terrain. Cluster analysis separated by the similarity the soil profiles in three different groups. Predominate classes Cambisols and Nitossols. Humic substances allowed to discriminate the taxonomic orders of soil and showed ?13C in soil with the humic, little change in isotopic signature, and soils with moderate. The observed changes were derived from C3 and C4 plants crops. The vineyards have similar chemical properties, and thus can be grouped in a single region for a determination of Geographical Indication. As for agricultural suitability evaluating different methods indicated that the evaluated profiles have low agricultural aptitude for annual crops. Therefore, it was proposed an adaptation of the evaluation system of agricultural suitability of the land for the growing of vines, taking into account specific conditions of altitude in the SC state. Allied to this, the drafting of the zoning proposal is an important tool for the implementation of new vineyards. === Os solos das regi?es produtoras de vinhos finos de altitude do estado de Santa Catarina apresentam caracter?sticas particulares decorrentes da sua litologia e dos elevados teores de mat?ria org?nica, que os diferenciam dos solos das grandes regi?es produtoras de vinho do mundo. O estudo foi realizado nas regi?es do meio oeste e serrana de Santa Catarina, abrangendo mais de 80 % das propriedades, onde foram realizadas descri??es e coletas de 38 perfis modais e em vinhedos espalhados em 45 propriedades rurais. Os objetivos foram: a) caracterizar a distribui??o e a intera??o dos fatores de forma??o dos solos e a taxa de intemperismo qu?mico; b) avaliar e quantificar os teores de carbono, fra??es h?micas nos perfis e o ?13C em horizontes superficiais de Cambissolos; c) caracterizar f?sica e quimicamente os solos dos vinhedos; e d) avaliar a aptid?o agr?cola atrav?s dos diferentes m?todos, com posterior adapta??o do Sistema de Avalia??o Agr?cola das Terras, para a cultura da videira, al?m de formular proposta de zoneamento para a vitivinicultura do estado. Os resultados indicam que a pedog?nese dos solos foi fortemente influenciada pelos fatores material de origem, clima e relevo. A an?lise do agrupamento separou pela similaridade os perfis de solo em tr?s grupos distintos. Predominam as classes de Cambissolos e Nitossolos. As subst?ncias h?micas permitiram discriminar as ordens taxon?micas de solos e o ?13C revelando pouca altera??o na assinatura isot?pica nos solos com horizonte A h?mico. Nos solos com A moderado foram observadas altera??es decorrentes de mudan?as nas coberturas (plantas C3 ou C4). As ?reas dos vinhedos apresentam atributos qu?micos similares, podendo ser agrupadas em uma regi?o ?nica para eventual determina??o de Indica??o Geogr?fica. Quanto ? aptid?o agr?cola, ? avalia??o atrav?s de m?todos usuais na literatura resultou em classes que indicam baixa aptid?o para culturas anuais. Diante disto, foi proposta adapta??o do sistema de avalia??o da aptid?o agr?cola das terras, para a cultura da videira, considerando condi??es especificas de altitude no estado de SC e associada ? elabora??o de uma proposta de zoneamento para a implanta??o de novos vinhedos.
