      abstract     = {Phosphorus (P) is essential for sustainable forest growth,
                      yet the impact of anthropogenic impacts on P leaching losses
                      from forest soils is hardly known. We conducted an
                      irrigation experiment with 128 mesocosms from three forest
                      sites representing a gradient of resin extractable P of the
                      A-horizon. On each site we selected a Fagus sylvatica and a
                      Picea abies managed subsite. We simulated ambient rain (AR),
                      anthropogenic nitrogen input (NI) of 100 kg (ha · a)−1
                      and forest liming (FL) with a dolomite input of 0.3 Mg (ha
                      · a)−1. Soil solution was extracted from the organic
                      layer, 10 cm depth and 20 cm depth of the mesocosms, and
                      analyzed for molybdate reactive phosphorus (MRP) and
                      molybdate unreactive phosphorus (MUP). Additionally, we
                      separated colloids from the soil solution using Asymmetric
                      Field Flow Fractionation for assessing the colloidal
                      fraction of total element concentrations. NI increased MRP
                      and MUP concentrations for all plots with one exception,
                      while FL decreased MRP and MUP with the exception of another
                      plot. While the irrigation treatments had little impact on
                      the P-richest site, MRP and MUP concentrations changed
                      strongly at the poorer sites. The colloidal fraction of P in
                      the soil solution equaled $38–47\%$ of the total P load.
                      Nitrogen input and liming also affected the Fe, Al, Ca, and
                      Corg contents of the colloidal fraction.},
