En el desarrollo de estrategias relativas al “Terroir”, se requiere una comprensión del grado de edafodiversidad. En un intento de inventariar y zonificar los suelos vitícolas de Castilla La Mancha (CLM), desde 2008 venimos realizando un análisis comprensivo y armonizado de las distintas coberturas edáficas, de los edafotaxa y de su distribución espacial. Fruto de este trabajo se desprende que, a pesar de que CLM ocupa una superficie dominantemente plana, existe gran variedad de sustratos litológicos y posiciones geomorfológicas, lo que conlleva una notable edafodiversidad, incluso a escala detallada. En concreto, se han caracterizado, según Soil Taxonomy (2014), fundamentalmente: Entisoles, Inceptisoles, Alfisoles y Ultisoles; mientras que según FAO-ISRIC-ISSS (2006) existen fundamentalmente: Cambisoles, Calcisoles, Luvisoles, Arenosoles, Gleysoles, Gypsisoles, Fluvisoles, Leptosoles, Regosoles, Acrisoles y Alisoles. Esta tipología de suelos la atribuimos fundamentalmente a procesos tales como alteración mineral parcial, calcificación o acumulación de carbonatos o yesos, argiluviación, rubefacción, etc. También cabe señalar, entre otros, dos procesos singulares y de moderada extensión territorial, como son la salificación y la gleización. Entre los cualificadores más comunes cabe citar los relacionados con la naturaleza de los materiales originarios o con procesos incipientes edafogenéticos, tales como Calcaric, Haplic, Profondic, Skeletic, Leptic, etc.; otros están relacionados con procesos de formación, tales como Chromic, Calcic, Luvic, etc. Sin embargo, desde nuestro punto de vista, se necesitan nuevos calificadores, especialmente en el caso de los Calcisoles.
Abstract
In the development of strategies related to terroir is required understand the pedodiversity. In an attempt to inventory and zoning the vineyard soils of Castilla La Mancha (CLM),(Spain), since 2008 we have been carrying out a comprehensive and harmonized analysis of the different soil coverings, the pedotaxa and their spatial distribution. The result of this work is that although CLM occupies a predominantly flat surface, which might suggest a certain monotony or scarce pedodiversity, given the variety of lithological substrates and existing geomorphological positions, a remarkable pedodiversity can be appreciated (including at a detailed scale). In effect, the pedodiversity or diversity of genetic types is very appreciable in CLM. Specifically they have been characterized, according to Soil Taxonomy (2014) mainly: Entisols, Inceptisols, Alfisols and Ultisols. According to FAO-ISRIC-ISSS (2006) there are mainly: Cambisols, Calcisols, Luvisols, Arenosols, Gleysols, Gypsisoles, Fluvisols, Leptosols, Regosols, Acrisols and Alisols. This type of soils are attributed to various processes such as partial weathering, calcification or accumulation of carbonates, argiluviation, rubefaction, gypsum accumulation, etc. Finally, it is worth mentioning two singular processes of slight territorial importance, such as the salification and gleization. Among the qualifiers, the most common are those related to the nature of the original materials or to incipient pedogenetic processes, such as Calcaric, Haplic, Profondic, Skeletic, Leptic, etc; others are related to soil forming processes, as Chromic, Calcic, Luvic, etc. However, in our point of view, new qualifiers are needed, especially in the case of Calcisols.
