What is the sub-specialization of soil science?
One sub-specialization of soil science is pedology, which focuses on the formation, classification, and mapping of soils. Another sub-specialization is soil fertility, which deals with the chemical, physical, and biological factors that affect the availability of nutrients for plant growth in soils.
Which layer of soil is the oldest?

What are the differences between top soil and sub soil?
Top soil refers to the top layer of soil that has a mix of vegetative matter and soil in it. The thickness of this layer varies from location to location. If you cut through sod with a spade and create a hole about 12" deep, you can see where the top soil turns into sub soil, which is a denser, lighter layer of soil. Generally, the top soil is darker because of the amount of decomposed plant matter in it - and the subsoil is lighter because it is mostly the mineral content: silt, clay, and sand.
What is located beneath soil layers?
Beneath soil layers, you can find bedrock, which is the solid rock layer that underlies soil. Below the bedrock, there may be other geological features like water tables, rock formations, or other geological formations depending on the location.
What does subsoil look like?
Subsoil typically appears compacted, dense, and less organic-rich compared to topsoil. It may contain fine particles like clay and silt, as well as minerals and nutrients leached down from the topsoil. Subsoil can vary in color, texture, and composition depending on the region and underlying geology.

Which 2 layers of the soil are least likely to contain humus?
The layer of soil that has little or no humus in it is the subsoil. The top layer of the soil has the most humus in it because the dead leaves fall from the plant and go back into the soil. Water and sun also help give the plant humus.
