Subsoil layer. Subsoil is the layer of soil under the topsoil on the surface of the ground. Like topsoil, it is composed of a variable mixture of small particles such as sand, silt and clay, but with a much lower percentage of organic matter and humus. The subsoil is labeled the B Horizon in most soil mapping systems.
"Subsoil" is a short story by American writer Nicholson Baker, which first appeared in The New Yorker periodical on June 27, 1994. [ 1 ] The story is about a man who meets his doom after being assaulted and forced by attacking, sprouting potatoes that lure agriculturalists into their sleepy Krebs Cycle .
Soil scientists use the capital letters O, A, B, C, and E to identify the master horizons, and lowercase letters for distinctions of these horizons. Most soils have three major horizons—the surface horizon (A), the subsoil (B), and the substratum (C). Some soils have an organic horizon (O) on the surface, but this horizon can also be buried.

Tropical Storm Gabrielle was a short-lived tropical cyclone that passed over North Carolina before tracking out to sea. The seventh named storm of the 2007 Atlantic hurricane season, Gabrielle developed as a subtropical cyclone on September 8 about 385 miles (620 km) southeast of Cape Lookout, North Carolina.
They also occur in humid to perhumid subtropical regions, where they are associated with Acrisols and Planosols. with a light-coloured, coarse-textured, surface horizon that shows signs of periodic water stagnation and abruptly overlies a dense, slowly permeable subsoil with significantly more clay than the surface horizon.
The solum (plural, sola) in soil science consists of the surface and subsoil layers that have undergone the same soil forming conditions. The base of the solum is the relatively unweathered parent material. Solum and soils are not synonymous. Some soils include layers that are not affected by soil formation. These layers are not part of the solum.
Also required is sufficient age to exhibit subsoil weathering and development. Limited leaching in aridisols often results in one or more subsurface soil horizons in which suspended or dissolved minerals have been deposited: silicate clays, sodium, calcium carbonate, gypsum, or soluble salts.
