The 'O' Horizon
Materials leached from horizon A are typically deposited in the B horizon of the soil profile. As water moves through the soil, it carries minerals and nutrients from horizon A and deposits them in the B horizon.
The soil horizon that has materials that are leached (removed) from upper layers and deposited is the B horizon. This layer receives minerals and nutrients that have been leached from the A horizon above it. The accumulation of these materials can lead to differences in color, texture, and nutrient content between the A and B horizons.
Topsoil consists primarily of the A horizon, which is the uppermost layer rich in organic matter and nutrients. Below the A horizon is the B horizon, which contains minerals leached from the upper layers.
Soil horizons consist of different layers with unique characteristics: O horizon: Organic matter such as leaf litter and decaying plant material. A horizon: Topsoil rich in organic matter, minerals, and living organisms. B horizon: Subsoil with enriched minerals leached from above. C horizon: Weathered parent material that has not undergone much alteration.
The first layer of soil is called the O Horizon, it is made of primarily humus. The second layer is the A horizon, this is the topsoil. Then there comes the E layer which is the eluvation layer. Next comes the B horizon which is the subsoil, then there is the C horizon which is the regolith, then the final layer is the R layer which is bedrock.

The A, B, and C horizons are found within the soil profile, which is composed of different layers of soil. The A horizon, also known as the topsoil, is the uppermost layer rich in organic material and nutrients. Below it is the B horizon, or subsoil, which accumulates minerals leached from the A horizon. The C horizon consists of weathered parent material from which the soil develops, providing the foundation for the upper layers.

The third soil horizon is known as the 'B horizon.' It is characterized by the accumulation of minerals and organic matter leached down from the upper layers, often leading to the development of distinct colors, textures, and structures. The B horizon plays a crucial role in nutrient retention and transport within the soil profile.
The B horizon of soil typically consists of deposits of minerals and organic matter leached down from the A horizon above it. It is characterized by accumulation of clay, iron, and aluminum compounds and can also contain roots and microorganisms. The B horizon plays a key role in controlling moisture and nutrient availability in the soil profile.
The soil layer that is also called subsoil is the B horizon. It is located below the A horizon (topsoil) and above the C horizon (bedrock). The subsoil contains less organic matter and is primarily composed of minerals and leached materials from the layers above.
The O horizon is the top layer made of organic material like plant litter. The A horizon is rich in organic matter and minerals, where most root activity occurs. The B horizon is known as the subsoil, containing minerals leached from the upper layers.
The three horizons of soil layers are the A horizon (topsoil), which is rich in organic matter and nutrients; the B horizon (subsoil), which contains minerals leached from the topsoil; and the C horizon (parent material), which is the weathered rock or sediment that the soil developed from.
The three horizons of a mature residual soil are the A horizon (topsoil), B horizon (subsoil), and C horizon (weathered rock material). The A horizon contains organic matter and is the most fertile layer for plant growth. The B horizon is rich in minerals leached from the topsoil. The C horizon is the least weathered and consists of partially weathered bedrock.
