Abstract
The Po di Volano Basin (687.5 km2) is a recently reclaimed alluvial territory, located south of the Po River Delta (northeaster Italy) and characterized by flat topography, intense agriculture and low population density. Under European Water Framework Directive (2000/60/EC) the whole basin has been designated as nitrate-vulnerable zone (NVZ). The objective of this work is to calculate a comprehensive nitrogen budget, both for superficial soils and the hydrological network, and compare individual terms to assess their reliability, particularly with respect to soil nitrogen losses and removal processes via denitrification.File in questo prodotto:
