tIn the frame of the Land Use/Land Cover Area Frame Survey sampling of topsoil was carried out on around22,000 points in 25 EU Member States in 2009 and in additional 2 Member States in 2012. Besidesother basic soil properties soil phosphorus (P) content of the samples were also measured in a singlelaboratory in both years. Based on the results of the LUCAS topsoil survey we performed an assessmentof plant available P status of European croplands. Higher P levels can be observed in regions where highercrop yields can be expected and where high fertilizer P inputs are reported. Plant available phosphoruslevels were determined using two selected fertilizer recommendation systems: one from Hungary andone from the United Kingdom. The fertilizer recommendation system of the UK does not recommendadditional fertilizer use on croplands with highest P supply, which covers regions mostly in Belgiumand the Netherlands. According to a Hungarian advisory system there is a need for fertilizer P input inall regions of the EU. We established a P fertilizer need map based on integrating results from the twosystems. Based on data from 2009 and 2012, P input demand of croplands in the European Union wasestimated to 3, 849, 873 tons(P2O5)/year. Meanwhile we found disparities of calculated input need andreported fertilizer statistics both on local (country) scale and EU level. The first ever uniform topsoilP survey of the EU highlights the contradictions between soil P management of different countries ofthe Union and the inconsistencies between reported P fertilizer consumption and advised P doses. Ouranalysis shows a status of a baseline period of the years 2009 and 2012, while a repeated LUCAS topsoilsurvey can be a useful tool to monitor future changes of nutrient levels, including P in soils of the EU.
