Vertical Phosphorus Migration in a Biosolids-Amended Sandy Loam Soil in Laboratory Settings: Concentrations in Soils and Leachates

Figure 2

Phosphorus (P) fractions in soil measured in the reference and biosolids treated soil columns: a) inorganic water-soluble P, b) inorganic loosely bound P, c) inorganic metal-bound P, d) inorganic calcium-bound P, e) organic labile P, f) organic moderately labile P, and g) organic nonlabile P. The error bars represent standard deviation among replicate samples.
