Figure 3


Fig. 3. Predicted activity of Al3+ and Al complexes (ai) as a function of depth in soil extracts. Activities were modeled using data from water extracts input into Visual MINTEQ. The insert graphs show the percentage of total Al (AlT) present as Al3+ or organically complexed Al as a function of pH for each treatment; • = Al3+, {nabla} = fulvic acid (FA) as FA2Al+, {blacksquare} = FA2AlOH, {diamond} = AlSO4+, {blacktriangleup} = AlHPO4+. Note: The 20- to 30-cm depth interval of the broadcast S treatment values are based on one sample. Concentrations of AlT were below the detection limit of the inductively coupled argon plasma–atomic emission spectroscopy for the other replicates.
