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.
Subsoiling is a slow operation and requires high power input: 60 to 100 horsepower (45 to 75 kW) to pull a single subsoil point through a hard soil. Typically, a subsoiler mounted on a compact utility tractor will reach depths of about 30 cm (12 in) and have only one thin blade with a sharpened tip.
The ideal soil condition for a vine is a layer of thin topsoil and subsoil that sufficiently retains water but also has good drainage so that the roots do not become overly saturated. The ability of the soil to retain heat and/or reflect it back up to the vine is also an important consideration that affects the ripening of the grapes.
The B horizon is commonly referred to as "subsoil" and consists of mineral layers which are significantly altered by pedogenesis, mostly with the formation of iron oxides and clay minerals. It is usually brownish or reddish due to the iron oxides, which increases the chroma of the subsoil to a degree that it can be distinguished from the other ...
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.
“Subsoil belongs to Ukrainians under the constitution,” Kseniiia Orynchak, founder of the National Association of Mining Industry of Ukraine, previously told the AP, suggesting a deal would need popular support.
"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 .
“We can speak about the value of the elements in the subsoil, but we have to understand it takes a lot of investment to extract, process and sell them.” Workers at a granite mine in the ...
