Agricultural P balances per country for 2005 & period 1905 - 2005
Van Dijk et al. (submitted) Van Dijk et al. (2015)
128 Mtons P accumulated in agricultural soils between 1905 -2005

Data & methods used
For EU-27 and individual Member States
As detailed as data allows: 93 sub flows
Imports, exports, losses and internal flows
Entire food system + non-food (e.g. forestry, detergents, pet food, etc.)
Main data sources: Miterra-Europe, CAPRI, FAOSTAT, Eurostat, reports, articles and experts
Time series if present in data (e.g. FAOSTAT, Eurostat)
Data for 2005 complete and checked, other base years possible with additional data input
Raw data is balanced based on mass balance principle
EU-27 corrections for intra/extra trade
![Page 8: EU wide overvie on P flows and data quality - Kimo van Dijk](https://reader035.vdocuments.us/reader035/viewer/2022062504/5875fa4c1a28ab77708b68f3/html5/thumbnails/8.jpg)
Data quality & monitoring challenges
Data quality: trade > production > consumption > recycling
Unclear definitions & not enough detail in data
Eurostat data is incomplete and inconsistent
Data gaps for waste flows & (new) recycling flows
Literature data mostly not recent and only specific base years
Trade databases not available for all products/materials
Data gaps requires data filling procedures & flow balancing
Industry data not publically available, sometimes commercially, but no peer reviewed
Uncertainties for most data unknown
Nutrient concentrations not monitored
From quantity to quality, from theory to practise

Phoshorus challenge
Non-renewable at human time scale
Spatially concentrated: geopolitical dependency and tension
Relatively low price, but price volatility (2008 case)
Lower P-rock quality:
β decreasing P content
β impurities (e.g. cadmium, uranium)
Pollution and eutrophication
