Abstract

The mid-mountain plateau of the Southern Franconian Jura exhibits base rocks of bedded and massive Upper Jurassic (Malm) carbonate rocks. These only provide a low protection potential against nitrate seepage. Hence, post-Jurassic covers may play an important role for a sustainable fresh water protection. Extensive tracer analyses in the Southern Franconian Jura offer the opportunity to investigate nitrate outputs on the basis on karst spring catchments. According to geomorphological and pedological criteria, the Southern Franconian Jura is characterised by 4 landscape types which reveal different protection potentials against nitrate seepage. Within the uncovered zone of the Franconian Jura the karst spring waters exhibit enhanced nitrate contents if the rate of agrarian land use is also enhanced in the catchments. This can be especially observed in the zone of bedded limestones
