La D.O. Uclés es una de las más jóvenes de España. Se encuentra situada entre las provincias de Cuenca y Toledo, ocupando una superficie total de viñedo de 1.700 ha. Se han estudiado 17 perfiles de la zona occidental, al Oeste de la Sierra de Altomira, los cuales se muestrearon y clasificaron siguiendo las nomas FAO (1996).
Los suelos estudiados se caracterizan por tener: pH alcalino (pH = 8,24), porcentajes de arcilla de un 20%, valores de conductividad eléctrica elevados (0,44 dS/m) y contenidos altos en CaCO3 (22%) El elemento mayoritario con mayor abundancia relativa es Si (con un valor medio de 196,6 g/kg), seguido por Ca (120,22 g/kg) y Al (63,86 g/kg). Entre los elementos traza llama la atención los elevados contenido en Sr (445,75 mg/kg) Rb (81,64 mg/kg) y Ba (223,61 mg/kg). Se han podido diferenciar varios grupos de suelos utilizando los contenidos en los elementos químicos anteriores, las características físico-químicas y las elevadas correlaciones entre contenido totales en hierro y aluminio con ciertos elementos químicos del grupo de las tierras raras.
Abstract
D.O. Uclés is one of the youngest wine quality areas in Spain. It is located between the provinces of Cuenca and Toledo, occupying a total vineyard area of 1,700 ha. We have studied 17 profiles from the western zone, west of the Sierra de Altomira, which were sampled and classified according to FAO standards (1996). The studied soils characteristics are: alkaline pH (pH = 8,24), percentages of clay of 20%, high electrical conductivity values (0,44 dS / m) and high contents in CaCO3 (22%). The element with more concentration is Si (with a mean value of 196,6 g / kg), followed by Ca (120,22 g / kg) and Al (63,86 g / kg). Among the trace elements, Sr is the more abundant (445,75 mg / kg) followed by Rb (81,64 mg / kg) and Ba (223,61 mg / kg). It has been possible to differentiate several groups of soils using the contents in the previous referenced chemical elements, the physical-chemical characteristics and the high correlations between the total content of iron and aluminium with certain chemical elements of the Rare Earth group.
