- B: A B horizon is a mineral horizon meaning it contains ≤ 17% organic C (about 30% organic matter) by weight. It is characterized by enrichment in organic matter, sesquioxides, or clay; or by the development of soil structure; or by a change of color denoting hydrolysis, reduction, or oxidation.

Feb 17, 2023 · 4) B Horizon – (Subsoil) Mostly found below the topsoil is another layer called the subsoil or horizon B. It is lighter in color than the topsoil due to lower humus content. However, it is comparatively more rigid and compact than the topsoil.
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.

Dec 13, 2023 · Horizon B, also referred to as the horizon of illuviation, is the intermediate layer where the materials that leached from horizon A have been redeposited. Compared to the A horizon, the B horizon contains more clay and less organic materials.
Jun 7, 2020 · Q: What soil horizon is subsoil? A: Horizon B is the subsoil. It is rich in minerals due to contents that have moved further down into the soil from the upper layers. Horizon B can contain high levels of iron, aluminum, gypsum, and silica clay. Q: Why do soil horizons form? A: Soil horizons form because of the effects of nature.
B - refers to the horizon directly below the A horizon called subsoil. Subsoil is located in the zone of accumulation, where majority of the minerals are leached or eluviated to through the process of illuviation.
Diagram of a soil profile showing approximate positions of major horizons (organic, O) and mineral (A, B, C). Not all horizons will be present in a particular soil.
