[[File:Redox1.png|400px|thumb|alt=image of different soil redox features|Description of common redox features in soil. From Redoximorphic Features for Identifying Aquic Conditions (North Carolina State, 1995)8.0)
- 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
