Feb 17, 2023 · During its formation, the soil is arranged in different layers. Each of these layers is called a soil horizon, and when these layers are arranged sequentially one above the other, it forms the soil profile. In other words, the soil profile is the vertical section of the soil exposed by a soil pit.

The soil is arranged in layers or in horizons. They are arranged during their formation. The layers or the horizons are basically known as the soil profile. The vertical section of the soil which is exposed by a soil pit is called the soil horizon profile. The layers of soil are easily identified by their colour and texture.

The soil is found in layers, which are arranged during the formation of soil. These layers called horizons, the sequence of layers is the soil profile. The layers of soil can easily be observed by their color and size of particles. The main layers of the soil are topsoil, subsoil and the parent rock. Each layer has its own characteristics.
Dig down deep into any soil, and you’ll see that it is made of layers, or horizons (O, A, E, B, C, R). Put the horizons together, and they form a soil profile. Like a biography, each profile tells a story about the life of a soil.
Soils are named and classified based on their horizons. The soil profile has four distinct layers: 1) O horizon; 2) A horizon; 3) B horizon, or subsoil; and 4) C horizon, or soil base (Figure \(\PageIndex{2}\)). The O horizon has freshly decomposing organic matter—humus—at its surface, with decomposed vegetation at its base. Humus enriches ...
