Reasons for difference of soil
between woodland 1 and2
• Woodland 1 has a darker soil colour due to high
content of humus
• Woodland 1 has a higher moisture because there
are plenty of trees and shrubs.
On the contrary,woodland 2 has a lower
moisture,because solar energy is easy to reaches
the ground surface
• Woodland 1 has a higher degree of decomposition
due to favourable micro-climate.
• Woodland 1 has fertile soil due to the existence of

Reasons for difference of litter
between woodland 1 and 2
• Woodland 1 has a higher degree of
decomposition due to high amount of trees.
And also,the wet and dark condition is
favourable for decomposer.
• Woodland 1 has more different content
– E.g.animals waste,decayed leaves,branches
due to the different kinds of trees and more
numbers of strata.
