“…Despite thirty years of regulatory effort to reduce nutrient pollution from agriculture, improvements are still important to be made (Kaspersen, Jacobsen, Butts, Jensen, Bøgh, Seaby, Müller & Kjaer 2016). In general, regulation of manure faces two problems.…”

“…On the local level, phosphorus budgets exist through farm-gate (Nielsen & Kristensen 2005), soil surface and soil system approaches (Kuosmanen & Kuosmanen 2013). The constructed budgets are usually based on case studies with selected farms (Nielsen & Kristensen 2005, Spiess 2011), or for sensitive areas such as lakes, specific catchments or fjords (Kaspersen et al 2016). Based on those studies the phosphorus balance ranges between 7 to 42 kg phosphorus/ha oversupply in Denmark and depends on the farm type, animal species, size and housing technology (Nielsen & Kristensen 2005).…”

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. Our results show that there is a large variability in the phosphorus balance within Denmark. Due to industry agglomeration 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 environmentally sensitive areas reinforces the need for further phosphorus regulation. Our findings show the importance of a combined spatially targeted regulation, which allows different levels of phosphorus application depending on local economic and environmental circumstances in combination with subsidizing manure processing technologies in phosphorus hot spots.
