(FIC) and niger seed (<jats:italic>Guizotia abyssinica<\/jats:italic> Cass.; NIC) processing industry in Ethiopia. The P fractionation removed more labile (54%) and H<jats:sub>2<\/jats:sub>SO<jats:sub>4<\/jats:sub>\u2013P (28%) from FIC than from NIC (18% labile, 12% H<jats:sub>2<\/jats:sub>SO<jats:sub>4<\/jats:sub>\u2013P). For the FIC residues after each extraction step, linear combination (LC) fitting of P <jats:italic>K<\/jats:italic>\u2010edge spectra provided evidence for the enrichment of Ca\u2010P after the NaOH\u2010extraction and its almost complete removal after the H<jats:sub>2<\/jats:sub>SO<jats:sub>4<\/jats:sub>\u2013treatment. The LC\u2010fitting was unsuccessful for the NIC samples, likely because of the predominance of organic P compounds. The different proportions of Ca\u2010P compounds between FIC (large) and NIC (small) were more distinctive in <jats:italic>L<\/jats:italic><jats:sub>2,3<\/jats:sub>\u2010 than in the <jats:italic>K<\/jats:italic>\u2010edge XANES spectra.
