Fig. 5. X-ray absorption near edge structure (XANES) spectroscopy of a high P soil and three P standards (P adsorbed to ferrihydrite, octacalcium phosphate, and hydroxyapatite). A linear combination of the spectra from the three standards matches the spectra from the soil and suggests P may exist in similar forms in the soil. From Beauchemin et al. (2003).
