SUB SOIL Meaning and
Definition
-
Subsoil is a term used in geology and soil science to refer to the layer of soil immediately beneath the topsoil. It is located directly underneath the top layer of earth, and is characterized by its distinct properties and composition.
Subsoil differs from topsoil primarily in terms of its mineral content, texture, and structure. While topsoil is rich in organic matter and nutrients necessary for plant growth, subsoil typically has a lower organic content and fewer nutrients. Instead, it is composed of mostly mineral particles such as sand, silt, and clay.
This layer of soil often has a denser and more compact structure than topsoil, as it is less influenced by the activity of plant roots and soil organisms. It is generally less permeable and may have poor drainage, resulting in higher water retention. Consequently, subsoil can have a significant impact on the overall fertility and health of the soil.
Subsoil plays a crucial role in water management as well. Due to its composition and structure, it affects the movement and storage of water within the soil profile. In areas with inadequate drainage, subsoil can retain excessive amounts of water, leading to waterlogging and poor aeration.
Understanding the characteristics and properties of subsoil is essential for soil management practices, such as agriculture and construction. By assessing and considering the subsoil composition, landowners, farmers, and engineers can make informed decisions regarding irrigation, drainage systems, and building foundations.

Etymology of SUB SOIL
The word "sub soil" originates from the Old English word "sūbe sēol" which was derived from the Proto-Germanic word "suða" meaning "under" or "beneath", and the Old English word "sēol" meaning "plowed land" or "soil". Over time, "sūbe sēol" evolved into "sub soil" in Modern English, referring to the layer of soil beneath the topsoil.
