Chernozem (/ ˈ tʃ ɜːr n ə z ɛ m / CHUR-nə-zem), [a] 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 soil and can produce high agricultural yields with its high ...
Also known as regur soil, black soil is ideal for growing cotton and is known as black cotton soil. They are rich in soil nutrients, such as calcium carbonate, magnesium, potash and lime. These soils are generally poor in phosphoric contents. [1] The black soils are made up of clayey soil, well known for their capacity to hold moisture.
A soil family category is a group of soils within a subgroup and describes the physical and chemical properties which affect the response of soil to agricultural management and engineering applications. The principal characteristics used to differentiate soil families include texture, mineralogy, pH, permeability, structure, consistency, the ...

An example of lateral earth pressure overturning a retaining wall. 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 and ...
