Exploring the Presence of Five Rare Earth Elements in Vineyard Soils on Different Lithologies: Campo de Calatrava, Spain

The aim of the work described here was to understand pedogeochemical signature five rare earth elements (REEs; Ce, Nd, La, Y, and Sc) in vineyard soils Campo de Calatrava (a unique territory with calcareous, volcanic metamorphic rocks). mean contents surface horizons Sc were 65.7, 32.0, 35.5, 18.8, 13.9 mg·kg–1, respectively. In subsurface Ce 62.8, Nd 31.1, La 35.7, Y 17.9, 14.4 mg·kg–1. results show that REEs area under investigation are order > Sc. has a very high range, value close 150 On other hand, concentrations higher on material than nonvolcanic material, while only values lower rocks. distributional maps suggest parent pedogenesis such as argillization calcium carbonate accumulation more important factors use REE-based fertilizers, except certain exceptional cases (consistent possible specific human impact after continuous fertilization).
