Hardpan is found in the A Horizon.
The C horizon typically contains parent rock material, which is the unweathered rock from which the soil has developed.
the horizon that contains topsoil is the A HORIZON
The bottom horizon in a soil profile that contains only partly weathered rock is called the C horizon. In this horizon, the rock is partially weathered and has started to break down into smaller particles, but has not fully transformed into soil yet.
The soil horizon that has the darkest and richest soil is usually the topsoil layer, known as the A horizon. This layer contains a high amount of organic matter and nutrients, making it ideal for plant growth.
Subsoil is typically found in the B-horizon of the soil profile. It is located below the topsoil layer (A-horizon) and contains less organic matter, more minerals, and is often denser than the surface soil.
The C horizon typically contains parent rock material, which is the unweathered rock from which the soil has developed.

the horizon that contains topsoil is the A HORIZON
B-horizon
The bottom horizon in a soil profile that contains only partly weathered rock is called the C horizon. In this horizon, the rock is partially weathered and has started to break down into smaller particles, but has not fully transformed into soil yet.
The soil horizon that has the darkest and richest soil is usually the topsoil layer, known as the A horizon. This layer contains a high amount of organic matter and nutrients, making it ideal for plant growth.
The O horizon contains the most organic matter. The O horizon overlies the A horizon which is known as the mineral horizon. O - organic A - mineral E - elluviation B - illuviation C - parent material R - bedrock This is the order in which you will see standard soil horizons.
The C and R horizon
The C horizon contains only party weathered rock.
Subsoil is typically found in the B-horizon of the soil profile. It is located below the topsoil layer (A-horizon) and contains less organic matter, more minerals, and is often denser than the surface soil.
The three major soil horizons are A horizon (topsoil), B horizon (subsoil), and C horizon (parent material). The A horizon is the top layer that contains organic matter and nutrients, the B horizon is the layer below that is richer in minerals, and the C horizon is the weathered rock or sediment from which the soil forms.
