Which layer of the soil is the B horizon?
subsoil
B HORIZON- This is the layer that we call “subsoil” and it is located just below the A Horizon. This layer has clay and mineral deposits and less organic materials than the layers above it. This layer is also lighter in color than the layers above it.
Does the B horizon have organic matter?
The B horizon, or subsoil, is often called the “zone of accumulation” where chemicals leached out of the A and E horizon accumulate. The word for this accumulation is illuviation. The B horizon has a lower organic matter content than than the topsoil and often has more clay.
Why does B horizon would normally contain more clay than the A horizon?
The B horizon has a lower organic matter content than than the topsoil and often has more clay.
What is E horizon in soil?
The E horizon is a mineral horizon with the main feature of eluvial loss of silicate clay, iron, aluminum, silicon, or some combination of these, leaving a residual concentration of sand and silt particles, and in which all or much of the original structure of rock or unconsolidated geological material has been …
What are A and B horizons?
The A and B horizons together are called the soil solum. They are a zone of accumulation where rain water percolating through the soil has leached material from above and it has precipitated within the B horizons or the material may have weathered in place.
What is horhorizon B fit?

After members enroll, they become eligible to receive a $20 reward for every month in which they make at least 12 visits to any of our 4,000 participating facilities across the United States.
What type of soil has a B horizon?
Most soils contain a B horizon except young soils or soils highly resistant to weathering (e.g., Entisols) in which an A horizon is directly underlain by a C horizon, an AC horizon or bedrock. Andisols, Gelisols, Histosols, Mollisols, and Vertisols may also lack a B horizon.
What are subsubsurface Horizons?
Subsurface horizons are used in Soil Taxonomy at all levels from soil orders to the subgroups ( Soil Survey Staff, 2014 ). Most soils contain a B horizon except young soils or soils highly resistant to weathering (e.g., Entisols) in which an A horizon is directly underlain by a C horizon, an AC horizon or bedrock.
