- The B horizon, also known as the subsoil, is a layer within the soil profile that lies beneath the A horizon and above the C horizon. It is characterized by the accumulation of minerals and nutrients leached from the upper layers, making it crucial for plant growth and nutrient cycling.
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.
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.
The B horizon is a mineral horizon below an A, E, or O horizon in which all or much of the original parent material structures or bedding features have been obliterated. The B horizon can have a range of pedogenic features resulting from translocation of soil materials, in situ processes, or both.
