<abstract>
<p>Phosphorus (P) cycling in freshwater wetlands is dominated by
biological mechanisms, yet there has been no comprehensive
examination of the forms of biogenic P (i.e., forms derived from
biological activity) in wetland soils.  We used solution
&lt;sup&gt;31&lt;/sup&gt;P NMR spectroscopy to identify and quantify P forms in
surface soils of 28 palustrine wetlands spanning a range of
climatic, hydrogeomorphic, and vegetation types. Total P
concentrations ranged between 51 and 3516 &amp;mu;g P g&lt;sup&gt;-1&lt;/sup&gt;,
of which an average of 58% was extracted in a single-step
NaOH–EDTA procedure. The extracts contained a broad
range of P forms, including phosphomonoesters (averaging 24% of
the total soil P), phosphodiesters (averaging 10% of total P),
phosphonates (up to 4% of total P), and both pyrophosphate and
long-chain polyphosphates (together averaging 6% of total
P). Soil P composition was found to be dependant upon two key
biogeochemical properties: organic matter content and pH. For example,
stereoisomers of inositol hexakisphosphate were detected exclusively
in acidic soils with high mineral content, while phosphonates were
detected in soils from a broad range of vegetation and
hydrogeomorphic types but only under acidic conditions. Conversely
inorganic polyphosphates occurred in a broad range of wetland soils,
and their abundance appears to reflect more broadly that of a
&quot;substantial&quot; and presumably active microbial community with
a significant relationship between total inorganic polyphosphates
and microbial biomass P. We conclude that soil P composition varies
markedly among freshwater wetlands but can be predicted by
fundamental soil properties.</p>
