The second layer in a soil profile, known as the B horizon or subsoil, is situated beneath the topsoil (A horizon). It typically has less organic matter and more clay, minerals, or weathered rock particles compared to the layers above. The B horizon often shows evidence of minerals or nutrients leaching from the topsoil above.

Which layer of a soil profile forms first from the bedrock?
The C horizon is the layer of a soil profile that forms first from the bedrock. It is the underlying layer that contains weathered rock fragments and shows the least amount of soil development.
In a well developed soil profile which horizon is the uppermost layer?
The uppermost layer in a well-developed soil profile is the O horizon, also known as the organic horizon. This layer consists of organic matter such as decaying leaves and plant material. It is typically found at the surface of the soil profile.
In well developed soil profile which horizon is the uppermost layer?
The uppermost layer in a well-developed soil profile is the O horizon, also known as the organic horizon. This layer consists of organic matter such as decomposing plant material and leaf litter. It is typically found at the surface of the soil profile.
Which is the second layer of a soil profile?
The second layer of a soil profile is called the B horizon. It is located beneath the topsoil (A horizon) and is often characterized by an accumulation of minerals leached from the topsoil above. The B horizon typically has a higher clay content and can also contain iron or aluminum oxides.

Soil profile?
A soil profile is a vertical section of soil that ranges from the surface to the bedrock. Each layer of a soil profile is referred to as a soil horizon.Horizon O is the top layer, where organic material is presentHorizon A is top soilHorizon B is subsoilHorizon C contains weathered rock.

What layer in the soil profile has the most organic material?
A is the layer of the soil profile in which most organic material is found.Specifically, there are five layers in the soil profile. The first, A layer of organic matter claims the first two inches and contains plant debris. The second, A layer of surface soil comprises the next ten inches down. Below it will be found the third, B layer of subsoil containing aluminum, clay, iron and organic compounds and going down 30 inches; the fourth, C layer of parent rock going down 48 inches; and the fifth, final, R layer of bedrock.

What do scientist call the top layer of a soil profile?
Scientists call the top layer of a soil profile the "O horizon" or "organic horizon." This layer consists of organic material such as leaves, twigs, and other plant debris that are in the process of decomposing.
What is the horizontal layer of soil?
The horizontal layer of soil is called a horizon. It is a distinct layer in the soil profile with unique characteristics such as texture, color, structure, and composition. Horizons are labeled with letters (O, A, E, B, C) based on their position and properties within the soil profile.
What layer of soil is the second layer?
The first layer is Litter, the third is Humus, so the second layer would be Duff.
