An increase in biologic activity
What is the third layer of soil
The first layer is Litter, the third is Humus, so the second layer would be Duff.
horizontal layer of soil is called horizon
The layer with soil is the lower mantle
An increase in biologic activity
The answer depends on the thickness of the covering layer. That, in turn will depend on what the soil is for: lawn will require less depth than flower beds.
where would you find the most decomposers in the soil layer
one thickness that lies on top of or under another one.
one thickness that lies on top of or under another one.
The depth is how deep the soil is and the thickness is the lkayer of the soil that is covered with how much the soil covering it

The topsoil is the finest soil layer. Soil 'layers' are called horizons.
What is the third layer of soil
The the bearing capacity of silt soil can be improved by:Compacting the soil to increase it's density.Increasing the depth of the foundation layer as the increased effective stress will act to increase bearing capacityThe use of geosynthetics may act to increase bearing capacityThe use of lime stabilisation / soil mixing techniques may also act to increase the bearing capacity of silt.

Topsoil is what you are standing on in your back yard. It is the most nutrient-rich layer of soil, and the fertility of any given land is quickly and roughly judged by the thickness of the topsoil, though there is more to it, of course.
