Soil Forming Processes
Illustrated by examples from SE Alaska
Hans Jenny explained soil formation using the
following equation Soil formation f (parent
material, climate, vegetation, topography and
time) Or how does one go from rock to soil? In
this case, we will start with beach sand
2
Situation Use Rebounding
3
Use a transect
Here time and vegetation vary

Soil Formation

• Hans Jenny explained soil formation using the
  following equation
• Soil formation f (parent material, climate,
  vegetation, topography and time)
• Time
• Parent material
• Climate
• Vegetation changed
• Why did we go from well drained, undifferentiated
  beach sand to a bog?
• How would you reverse?
