Brown Earth
Deciduous vegetation
- Leaf litter, well-decomposed to form fermentation layer
- Mild acid humus - mull
- Rapid decomposition due to earthworms and mild temps
- Dark brown due to humus staining from bove
- Loamy texture
- Well aerated due to tunnelling by organisms
- Merged horizons due to organisms
- Possible capillary uplift in summer depositing nutrients in A horizon
- Possible seasonal iron on in winter
- Deeps roots allow chemicals lost by leaching to be brought back up
- Lighter brown as there is less humus
- Light clay texture
- Well weathered parent material broken up by warmer temperatures and tree roots
