  		Fig. 1. a. Changes in porewater–floodwater phosphate and porewater Fe2+ concentrations for lower-P soils. Note the different scale for Fe(II) in Soil 4.

b. Changes in porewater–floodwater phosphate and porewater Fe2+ concentrations for Soils 6 and 8 (lower-P soils with a higher P release to floodwater than those in Fig. 1a)

  		Fig. 3. Relationship between the porewater phosphate concentration and soil test parameters; (a) pH 4.8 NH4–acetate (modified Morgan's); (b) the degree of phosphorus saturation (DPS), calculated as the ratio of fluoride-extractable P (modified Morgan's with F-) to the phosphorus adsorption index (PAI)
