- 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.

Feb 17, 2023 · Five factors that cause soils and their horizons to differ from one another are parent material, weather or climate, topography, biological factors such as the type of plants and animals living on the soil, and time.
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.
A horizon is defined in Soil Taxonomy as “a layer, approximately parallel to the surface of the soil that is distinguishable from adjacent layers by a distinctive set of properties produced by the soil-forming processes” (Soil Science Division Staff, 2017).
Jun 7, 2020 · Extracted sections of soil (the soil profile) show the soil horizons and how they compare to each other. Anyone analyzing the soil layers and the materials within can learn about the origin of the soil, including its parent material, and well as any other useful information about the mineral contents.
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 horizon description system begins by splitting soil horizons into two distinct groups: organic and mineral horizons. Organic horizons are those that contain 17% or more organic carbon; mineral horizons have less than 17% organic carbon.
Soil horizons are important markers in trench exposures because they indicate the location of past ground surfaces in the stratigraphic sequence, and their degree of development may indicate the length of time that surface was stabilized.
