The top layer of soil, known as the topsoil or A horizon, typically has the highest biological activity due to its organic matter content and availability of nutrients. This layer is where most plant roots, microbial organisms, and soil fauna are concentrated, making it a hub of biological activity in the soil profile.
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.
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.
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.

A biolayer is a layer of biological material.

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.
A bioprinter is any device which performs bioprinting - the construction of a biological structure by computer-aided, automatic, layer-by-layer deposition, transfer and patterning of small amounts of biological material.

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.
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.
