Anna Mårtensson Department of Soil and Environment, Swedish University of Agricultural Sciences, Uppsala, SwedenCorrespondence: Anna MårtenssonDepartment of Soil and Environment, Swedish University of Agricultural Sciences, Box 7014, SE 750 07, Uppsala, SwedenTel [phone]Fax [phone]Email [e-mail]: The number of vineyards in Sweden is increasing, but vineyards may have a negative environmental impact, resulting in further eutrophication of surface waters. In this study, the nutrient balance was calculated for four vineyards in southern Sweden. Comparisons of the results with nutrient deficits/surpluses under comparable land uses (arable, pasture) revealed only minor surpluses from the vineyards. Therefore, current fertilization strategies for Swedish vineyards do not appear to raise environmental concerns concerning eutrophication risk.Keywords: cold climate wine, eutrophication
