摘要：Nitrogen is an important input to agricultural production but also detrimentally affects the environment. Using data on more than 1000 Austrian municipalities, we provide a statistical analysis of (1) the determinants of nitrate concentration in groundwater, and (2) the predictive abilities of the OECD Nitrogen Balance as agri-environmental indicator. We find that the proportion of cropland exerts a positive effect on the nitrate content in groundwater. Also environmental factors are found to be important. Higher average temperature and precipitation lead to lower nitrate pollution of groundwater. We also show that the OECD Nitrogen Balance proves to be a good predictor for nitrate pollution, but its predictive power can be improved if average precipitation of a region is accounted for
