Phosphorus budget and P stocks

Phosphorus (P) budget in the European agricultural soils. We provide shape files with main inputs (fertilizers, manure, chemical weathering, atmospheric deposition) and the losses by water erosion. In addition, we model the Total P and the relevant P stocks (available/Olsen, Total). We also make available 21,681 LUCAS point data with measured Total P.

We estimate the Phosphorus (P) budget from agriculural lands of EU and UK (c.a 173 million ha). This takes into account the P inputs (fertilizers, manure, chemical weathering, atmospheric deposition) and the P outputs (crop production, plant residues removal, losses by erosion) for the period 2011–2019. The P budget and the P inputs/ouptus are available at NUTS2 (Regional scale) and country scale. In addition, we estimate the P displacement and losses due to water erosion at catchment scale and aggregate them at sea outlet.

Finally, we make available the datasets for both Total P and Available P (olsen) concentration and stocks. This is based on the Land Use/Cover Area frame Survey (LUCAS) topsoil data include measured values for almost 22,000 samples for both available and total P.
 

Main highlights

a) In the EU and UK, we estimated an average surplus of 0.8 kg P ha−1 yr−1

b) We estimated the total P in agricultural topsoil (0-20 cm) at a mean of 1412 kg ha−1.

c)  The P available to total P ratio is 1:17 for the whole study area.

d)  The inorganic fertilizers and manure contribute almost equally as P inputs.

e) Total P losses to river basins and sea outlets estimated to around 100,000 t P yr−1.

Data available:

a) Shapefiles for P inputs (fertilizers, manure, chemical weathering, atmospheric deposition) and the losses by water erosion.

b) The P budget and the P inputs/ouptus are available at NUTS2 (Regional scale) and country scale.

c) Total P concentration (GeoTiff) and the P available / Total P stocks in EU agricultural soils.

d) 21,681 LUCAS point data with Total P (csv, shapefiles) (update Feb 2023).
