                      applied to arable soils, a significant proportion of which
                      becomes stabilized by mineral components and in part
                      subsequently becomes unavailable to plants. However, little
                      is known about the relative contributions of the different
                      organic and inorganic P bound to Fe/Al oxides in the smaller
                      soil particles. Alkaline (NaOH–Na2EDTA) extraction with
                      solution 31P-nuclear magnetic resonance (31P-NMR)
                      spectroscopy is considered a reliable method for extracting
                      and quantifying organic P and (some) inorganic P. However,
                      any so-called residual P after the alkaline extraction has
                      remained unidentified. Therefore, in the present study, the
                      amorphous (a) and crystalline (c) Fe/Al oxide minerals and
                      related P in soil aggregate-sized fractions (> 20, 2–20,
                      0.45–2 and < 0.45 μm) were specifically extracted by
                      oxalate (a-Fe/Al oxides) and
                      dithionite–citrate–bicarbonate (DCB, both a- and c-Fe/Al
                      oxides). These soil aggregate-sized fractions with and
                      without the oxalate and DCB pre-treatments were then
                      sequentially extracted by alkaline extraction prior to
                      solution 31P-NMR spectroscopy. This was done to quantify the
                      P associated with a- and c-Fe/Al oxides in both alkaline
                      extraction and the residual P of different soil
                      aggregate-sized fractions. ...},
