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.
Jun 7, 2020 · What Are Soil Horizons? Soil horizons, according to Britannica, are layers of soil that are underground, which “develop from the combined actions of living organisms and percolating water.” This definition basically means that many living creatures and other forces of nature shape the soil in a way that creates identifiable layers.
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.
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.
The O horizon is the upper layer of the topsoil which is mainly composed of organic materials such as dried leaves, grasses, dead leaves, small rocks, twigs, surface organisms, fallen trees, and other decomposed organic matter.

Soil scientists, who are also called pedologists, observe and describe soil profiles and soil horizons to classify and interpret the soil for various uses. Soil horizons differ in a number of easily seen soil properties such as color, texture, structure, and thickness.
Soil texture affects soil behavior, in particular its retention capacity for nutrients and water. Soil components larger than 2.0 mm are considered as rock and gravel and can be included in textural class.For example, a sandy loam soil with 20% gravel would be called a gravelly sandy loam. When the organic component of a soil is substantial ...
