      abstract     = {Phosphorus (P) is an essential element for life on Earth,
                      with an important and oftentimes unaccounted organic
                      biogeochemical component. Current methods for the
                      quantification of different organic P compounds in
                      environmental samples (e.g., soils, sediments) are based on
                      extraction techniques and often associated with incomplete P
                      recovery or sample changes. In this study, we present a
                      protocol for the quantification of different organic and
                      inorganic P species in soils using synchrotron-based X-ray
                      absorption near-edge structure (XANES) spectroscopy at the P
                      L2,3-edge. Its accuracy and precision was evaluated by
                      analyzing 40 standard mixtures composed of seven different
                      inorganic and organic P compounds (with a mean of R2 =
                      0.85). In addition, we quantified the P species of two soils
                      and two agro-industrial byproducts using P L2,3-edge XANES
                      spectroscopy and the results were compared with those
                      obtained by P K-edge XANES or 31P NMR spectroscopy. Using
                      the P L2,3-edge, we identified different organic P species,
                      including those not identified by the common P K-edge XANES.
                      However, there is a consistent underestimation of organic
                      polyphosphates. Overall, the application of P L2,3-edge
                      XANES provides a higher level of information than by P
                      K-edge XANES, although the ubiquitous use of this novel
                      methodology is still limited to samples with a phosphorus
                      content above 3 mg g–1.},
