A soil profile is a vertical section of soil that displays all its layers (horizons) from the surface down to the unaltered parent material.
It provides a comprehensive view of the soil formation process, including organic matter accumulation, leaching, and weathering.
Information Key Points:
A soil profile includes distinct layers called horizons.
Shows the sequence: O → A → B → C → R (sometimes O horizon is absent).
Important for agriculture and soil management.
Knowledge Booster (Other Option Information):
Soil horizon:
A single layer within the soil profile.
For example, A-horizon (topsoil), B-horizon (subsoil), etc.
Regolith:
Refers to the loose, unconsolidated material above solid bedrock.
Parent material:
The underlying geological material (often bedrock or unconsolidated deposits) from which the soil develops.
It is the C or R horizon in the soil profile.
