Relationship between the occurrence of selected metals in vineyard soil and their concentrations in fruits of the grapevine cultivated on this soil were studied. That issue is weakly recognized up to now. The methods used for analyzing this relation, which are aimed at determination of optimal mineral and chemical fertilizer doses, still need development. On the basis of the obtained results it was found that analyzed grapes cultivars (Aurora and Rondo) show tendency to accumulate potassium and magnesium in higher concentrations than zinc. The results of such analysis could allow determining the nutrient demand of grapevine that can result in its enhanced suitability for wine production. It should be emphasized that such kind of analyses should be realized regularly and be applied to broader spectrum of elements and heavy metals
