abstract = {Understanding and quantification of phosphorus (P) fluxes
are key requirements for predictions of future forest
ecosystems changes as well as for transferring lessons
learned from natural ecosystems to croplands and
plantations. This review summarizes and evaluates the recent
knowledge on mechanisms, magnitude, and relevance by which
dissolved and colloidal inorganic and organic P forms can be
translocated within or exported from forest ecosystems.
Attention is paid to hydrological pathways of P losses at
the soil profile and landscape scales, and the subsequent
influence of P on aquatic ecosystems. New (unpublished) data
from the German Priority Program 1685 “Ecosystem
Nutrition: Forest Strategies for limited Phosphorus
Resources” were added to provide up-to-date flux-based
information.Nitrogen (N) additions increase the release of
water-transportable P forms. Most P found in percolates and
pore waters belongs to the so-called dissolved organic P
(DOP) fractions, rich in orthophosphate-monoesters and also
containing some orthophosphate-diesters. Total solution P
concentrations range from ca. 1 to 400 µg P L−1, with
large variations among forest stands. Recent sophisticated
analyses revealed that large portions of the DOP in forest
stream water can comprise natural nanoparticles and fine
colloids which under extreme conditions may account for
$40–100\%$ of the P losses. Their translocation within
preferential flow passes may be rapid, mediated by storm
events. The potential total P loss through leaching into
subsoils and with streams was found to be less than 50 mg P
m−2 a−1, suggesting effects on ecosystems at centennial
to millennium scale. All current data are based on selected
snapshots only. Quantitative measurements of P fluxes in
temperate forest systems are nearly absent in the
literature, probably due to main research focus on the C and
N cycles. Therefore, we lack complete ecosystem-based
assessments of dissolved and colloidal P fluxes within and
from temperate forest systems.},
