Fig. 3. Relationships between (A) inorganic P (H₂O + 0.5 mol L^–1 NaHCO₃ + 0.1 mol L^–1 NaOH + 1.0 mol L^–1 HCl) and orthophosphate (determined by nuclear magnetic resonance [NMR] analysis of 0.5 mol L^–1 NaOH–0.05 mol L^–1 ethylenediamine tetra-acetic acid [EDTA] extracts) and (B) the organic P (0.1 mol L^–1 NaOH + 1.0 mol L^–1 HCl) and phytic acid (determined by NMR analysis of 0.5 mol L^–1 NaOH–0.05 mol L^–1 EDTA extracts).
