Loam (the high-humus definition, not the soil texture definition) may be used for the construction of houses, for example in loam post and beam construction. [6] Building crews can build a layer of loam on the inside of walls, which can help to control air humidity. Loam, combined with straw, can be used as rough construction material to build ...
Chernozem (from Russian: чернозём, romanized: chernozyom, IPA: [tɕɪrnɐˈzʲɵm]; "black ground"), [ 1][ 2] also called black soil, regur soil or black cotton soil, is a black-colored soil containing a high percentage of humus [ 3] (4% to 16%) and high percentages of phosphorus and ammonia compounds. [ 4] Chernozem is very fertile ...
Lateral earth pressure. The lateral earth pressure is the pressure that soil exerts in the horizontal direction. It is important because it affects the consolidation behavior and strength of the soil and because it is considered in the design of geotechnical engineering structures such as retaining walls, basements, tunnels, deep foundations ...
A fourth term, loam, is used to describe equal properties of sand, silt, and clay in a soil sample, and lends to the naming of even more classifications, e.g. "clay loam" or "silt loam". Determining soil texture is often aided with the use of a soil texture triangle plot. [5] An example of a soil triangle is found on the right side of the page.
Soil moisture is the water content of the soil. It can be expressed in terms of volume or weight. Soil moisture measurement can be based on in situ probes (e.g., capacitance probes, neutron probes) or remote sensing methods. [1] [2]
The most common engineering classification system for soils in North America is the Unified Soil Classification System (USCS). The USCS has three major classification groups: (1) coarse-grained soils (e.g. sands and gravels ); (2) fine-grained soils (e.g. silts and clays ); and (3) highly organic soils (referred to as "peat").
Soil bulk density, when determined at standardized moisture conditions, is an estimate of soil compaction. [3] Soil porosity consists of the void part of the soil volume and is occupied by gases or water. Soil consistency is the ability of soil materials to stick together. Soil temperature and colour are self-defining.
Soil formation. Soil formation, also known as pedogenesis, is the process of soil genesis as regulated by the effects of place, environment, and history. Biogeochemical processes act to both create and destroy order ( anisotropy) within soils.
