Although there is no general European Phosphorus (P) Directive or Regulations, several European Member States address the agricultural phosphorus losses by phosphorus application restrictions in their legislation. An inventory of this phosphorus legislation among European countries was performed in 2014, as un update of the inventory of 2007 (COST action 869). Some countries or regions do not have direct P application restrictions in addition to the fertilizer N and manure N restrictions in the Nitrate Vulnerable Zones, while other countries have detailed maximum P application rates. Comparing regulations is complicated since various systems exist, e.g. maximum application rates and balance systems on farm or field scale. Furthermore, the type of restricted P fertilizer varies: e.g. all types of P forms applied, only manure or only chemical fertilizer. Several countries and regions have crop type dependent maximum phosphorus application rates. For grassland, maize, cereals, potatoes and sugar beets the maximum application rates are compared among Member States. In some Member States the soil P content is taken into account based on specific soil P tests, i.e. P application standards are lower for soils with high P status resulting in reduced P accumulation in these soils. In addition, buffer zone widths along surface waters are compared among Member States. It is concluded that phosphorus legislation in European countries and regions varies widely, and that better agri-environmental sound approaches are needed to reduce agricultural P losses effectively. Both the current member state approaches as well as agri-environmental approaches will be presented and discussed.
