Feb 17, 2023 · There is the significant importance of soil horizon in soil science. It allows one to understand the several processes that play a role in soil development and determine the different soil types. It also forms the basis for soil classification.
Vertic horizon: A horizon affected by argillipedoturbation, which is the disruption and mixing of the horizon caused by shrinking and swelling of the clayey soil mass. It is characterized by the following: 1) irregular shaped, randomly oriented, intrusions of displaced materials within the solum.
Horizons. The action and interaction of soil-forming processes as influenced by soil-forming factors gives rise to distinct soil horizons. These layers are assigned distinctive alphabetic symbols as a form of shorthand for their characteristics.
A soil horizon is a layer of mineral or organic soil material approximately parallel to the land surface that has characteristics altered by processes of soil formation. It differs from adjacent horizons in properties such as color, structure, texture, and consistence and in chemical, biological, or mineralogical composition.
The A Horizon, also known as the topsoil, is the layer where most plant roots grow. It is rich in organic matter and microorganisms and is the most nutrient-rich and productive layer in a soil profile. The A Horizon is important for agriculture as it supports the growth of crops and other plants.

A soil horizon is a layer parallel to the soil surface whose physical, chemical and biological characteristics differ from the layers above and beneath. Horizons are defined in many cases by obvious physical features, mainly colour and texture.
