ABSTRACT
In Castilla-La Mancha region (Spain) where more than 500.000 hectares are occupied by vineyards, soil
mineral content could be crucial to determinate the quality of the products and the economic sustainability of
the vineyard. The soils of such extended region (80.000 km 2) in the center of the Iberian Peninsula are varied
and different. However, in the area of maximum intensity culture of wine grapes, soils have a high content in
calcium carbonate (Amoros et al, 2013). When chlorosis symptoms appear are usually related with the iron
deficiency but not only this element is involved in these nutritional problems (Marschner, 2011).
Data from 150 soil profiles all around Castilla-La Mancha were taken following the procedure described
in other publications (Pérez-de-los-Reyes et al., 2015). X ray fluorescence is the analytical technique used to
measure both soil and leaf concentration of mineral elements. From all obtained data, mean content of surface
horizons (A and B) in Ca, Fe, Mn and Zn are studied and compared with leaf content in these elements.
Stagraphic® Centurion 17.1.02 program was used to perform multivariate analysis. These data were georeferenciated and displayed in spatial distribution maps using Surfer 9.8.669 (©Golden Software Inc. 2009).
Concentration in soil of the considered elements are: 108.0 ± 28.8 g·kg -1 for Ca; 22.1±1.4 g·kg-1 for Fe;
380.0 ±740.0 mg·kg-1 for Mn and 32.6± 14.0 mg·kg-1 for Zn. Leaf concentration measured for the same
elements are: 24.4 ± 49.4 g·kg-1 for Ca; 440.0±742.0 mg·kg-1 for Fe; 130.0 ±136.0 mg·kg-1 for Mn and 20.3±
12.9 mg·kg-1 for Zn. Zn levels are more critical as average than Fe levels in soil and leaves for plant nutrition.
A multivariate analysis was performed for these variables and the best correlation was for Fe and Zn soil
content.
This work contributes to ascertain if the concentration and balance of Ca, Fe, Zn and Mn in soil is reflected
in leaf composition for Castilla-La Mancha vineyards. Critical concentrations should be considered in order to
explain and prevent symptoms of deficiency that could decrease quantity and quality of wine grapes.
Keywords: Iron, calcium, zinc, vineyard, nutrition mineral.
