generally refers to distinct soil layers (called the B and C horizons) below the topsoil; often with high clay contents.
The usually less fertile soil below the topsoil.
The B Horizon, or roughly the part of the solum below the depth of plowing.
Layer of soil below the topsoil, usually less fertile and of poor structure.
B horizon usually derived from rock by in situ weathering.
The part of the soil profile beneath the surface soil that has been altered from its original geologic characteristics. In many instances, it is called a "B horizon."
the layer of soil between the topsoil and bedrock
The layer or bed of earth beneath the surface soil.
A collective and general term for the layers of soil below the uppermost layer or topsoil. It can consist of sand, silt and clay but has little, if any, humus or other organic matter. Subsoil provides structure, holds moisture, and is a good foothold for rooting plants.
The soil lying below that which is cultivated
the mineral-rich layer of the soil, lying underneath topsoil and above regolith from which it is derived; weathered to a stage where the parent material (rock or sediment) or no longer recognisable.
soil below the usual depth of cultivation, brown or reddish colored soil with more clay than surface soils
Sous-sol Unterboden, m Subsuelo The layer of soil below the topsoil which is usually less fertile and of poorer texture.
A layer of soil beneath the topsoil that has lower organic content and higher concentrations of fine mineral particles; often contains soluble compounds and clay particles carried down by percolating water.
The layer of soil beneath the topsoil made of pebbles.
In general, that part of the soil below thedepth of plowing.
(3) the B horizon of soils with distinct profiles, or the soil below the plowed soil (or its equivalent of surface soil) in soils with weak profile development.
A light-colored soil layer usually found beneath the topsoil. It contains little or no humus.
That layer of soil normally below cultivation depth but which has a great effect on the performance of the topsoil. Subsoiling is an operation where a deep cultivator runs through the subsoil at a depth of around 450 mm when the soil is dry to shatter it.
the layer of soil underneath the topsoil
Indicated by a different soil color and a complete lack of artifacts. Once subsoil is found the excavation of the square can stop.
Technically, the B horizon; roughly the part of the solum below plow depth.
That part of the soil profile below plow depth. Usually considered unsatisfactory for plant growth.
The soil layer which lies beneath the true soil and which contains almost no organic matter.
Subsoil is the layer of soil under the topsoil on the surface of the ground. The subsoil may include substances such as clay and has only been partially broken down by air, sunlight, water, etc., to produce true soil. Below the subsoil is the substratum, which can be residual bedrock, sediments, or aeolian deposits, largely unaffected by soil forming factors active in the subsoil.
