AB  - Sequential chemical extraction and synchrotron-based XANES spectroscopy 
      techniques were used to identify P species in two ashes before and after addition 
      to a prairie soil. The used ashes were: meat and bone meal ash (MBMA) and dried 
      distillers grains ash (DDGA) plus mineral P fertilizer (MP) for comparison. Soil 
      treated with MP contained higher content of resin-Pi and NaHCO(3)-Pi followed by 
      DDGA and MBMA. The MBMA amended soil had the highest (47%) proportion of the soil 
      P contained in recalcitrant HCl extractable fraction, reflecting more Ca-bound P 
      present and being formed in soil after application. Analysis of both ashes with 
      XANES spectroscopy before application to soil revealed that MBMA had strong 
      spectral features consistent with hydroxyapatite (Ca(5)(PO(4))(3)(OH)). DDGA 
      exhibited spectral features consistent with a mixture of several Mg and K 
      phosphate salts rather than a single mineral species. The distinctive features in 
      the XANES spectra of both ashes largely disappeared after amendment to the soil, 
      suggesting transformation to different P forms in the soil after application. It 
      is also possible that the added amount of P to the studied soil via DDGS or MBMA 
      was small enough so that P speciation is not different from the background P 
      level.
