Detailed explanation-1: -Soil profile is a vertical section of the different layers which make up soil.
Detailed explanation-2: -A vertical section through the soil, showing different layers of soil is called soil profile.
Detailed explanation-3: -Soil profile is the name given to the vertical section of all the different layers of soil. Soil profile helps us understand the composition of different types of soils and the properties of each layer of soil.
Detailed explanation-4: -A soil profile is a vertical section of soil like the diagram above. It allows you to examine the structure of soil. A soil profile is divided into layers called horizons. The main soil horizons are A, B, C and D.
Detailed explanation-5: -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 31.2. 2). The O horizon has freshly decomposing organic matter-humus-at its surface, with decomposed vegetation at its base.
