Concentrations of chlorophyll derivatives in the organic matter of woodland, swamp, and pond soils are clearly related to water logging and level of soil water table. Average amounts of pigment (in arbitrary units per g ignition loss) are as follows: woodland hums layers, 0.5, swamp-hummock peats 0.3, swamp-flat peats 0.8, swamp-hollow peats 1.8, pond muds 9.6. The marked difference in amounts of pigment between pond muds and waterlogged peats of the swamp hollows reflects the much greater pigment concentration in phytoplankton than in the rooted plants of swamp and forest vegetation.
