Table 6. Results of linear combination fitting of P K-edge XANES spectra of forest soil microaggregates size fraction of the control without clear-cut, 10, and 24 month after clear-cut.
Values in brackets shown the standard deviation of averaged fit proportions in the case when fits were not significantly different to each other (Hamilton P ≤ 0.05) based on the r-factor.
