New England Soil Profiles

Redoximorphic Features (a.k.a Soil Mottles)

This photo shows redox concentrations (bright yellowish-brown colors 10YR5/6 munsell color), redox depletions (gray colors - 2.5Y 6/1 colors) with a pale yellowish-brown matrix color (2.5Y 5/3 munsel color).

This photo shows a redox depletion (5BG 6/0 munsell color) along a dead root channel (visible in the center) with redox concentrations (10YR 5/6) around the depleteion.

Photographs showing redoximorphic features (soil mottling) which are color patterns in the soil formed by the oxidation and reduction of iron and/or manganese caused by saturated conditions within the soil. Redoximorphic features are used to estimate the depth to seasonal high watertable.
