Abstract

Total nutrient content of soils and quantity of potentially available part in plants are determined in this study. Main affecting factors of nutrient uptake might be the geochemical conditions of soils and the applied agro-technological methods, while the real uptake of plants can be influenced by precipitation and evaporation conditions beside the rootstock and the used grafted scions. The element content of grape berries of Vitis vinifera L. Kékfrankos cultivar was studied in identical rootstocks and scions at different production areas in Northern Hungary, during two consecutive years with somehow contrasting natural precipitation. Significant effect of the precipitation was found on the elements-uptake by the plants in general. Furthermore, it was also found, that the role of production area becomes increasingly important in grape production and quality, as well. Higher precipitation resulting greater elemental content and variability in comparison with the drier years.
