Abstract: In this paper, we analyze the phosphorus balance as a result of manure application on the parish level for Denmark and investigate its local geographic distribution. For our analysis, we determine phosphorus loads for the five main animal groups and the phosphorus demand of the fifteen major crop categories. To identify statistical significant local patterns of phosphorus over- and undersupply we apply Getis-Ord Gi* hot spot analysis. Our results show that there is a large variability in the phosphorus balance within Denmark. Statistically significant hot spots appear mainly along the west coast, while cold spots are predominantly present on southern and eastern coasts towards the Baltic Sea. The proximity of oversupply areas to water bodies and other environmental sensitive areas reinforces the need for further phosphorus regulation. These findings show the importance of a spatial targeted regulation, which allows different levels of phosphorus application depending on local economic and environmental circumstances, e.g., distance to an environmental sensitive region.
