Influence of soil attributes on ?Petit Verdot? productivity in the São Francisco Valley, Brazil

The São Francisco Valley is a pioneer in the production of fine grapes for wine. The region has excelled on the national economy, being the only region in the world that produces two harvests a year. Studies aiming to characterize the potential grapevine growing regions indicate the potential of several cultivars adapted to local conditions and suitable to contribute for the typicality of the grapevine products of the region, as for example, the Petit Verdot cultivar (Ibravin, 2012). Some soil attributes, important to grape and wine quality, are related to water and nutrient availability (Leewen et al., 2004; Wang et al., 2015). The objective of this work is to relate the physical and chemical properties of soils to the productivity of the vine, Petit Verdot cultivar, in the São Francisco Valley
