The term redoximorphic refers to the reduction and oxidation chemical reactions and the resulting appearance or morphology of the soil horizon. While color is often used to indicate the presence of oxidized or reduced zones on soil, it is not the only indicator that can be used. This page provides information to help characterize and identify oxidation-reduction (redox) conditions in a soil. For information and a discussion on redox in soil, [https://stormwater.pca.state.mn.us/index.php?title=Soil_chemical_properties_and_processes#Redox_.28oxidation-reduction.29_processes link here]. Several links are also included at the bottom of this page. These provide information on redox chemistry in soil and how it affects soil and soil processes, including pollutants in soil. | The term redoximorphic refers to the reduction and oxidation chemical reactions and the resulting appearance or morphology of the soil horizon.

- Cold temperatures (inhibit biological activity which utilizes iron and manganese as electron acceptors)
- Low amounts of iron
- Oxygenated groundwater
- Presence of redoximorphic features may not reflect the current hydrologic condition
- Recently drained soils may retain presence of reduced features
- Changes in microclimate are indicated by sharp boundaries in the soil
- Contemporary features should have diffuse boundaries
