regosol
Noun: A type of soil consisting of unconsolidated (loose) mineral material, typically from freshly deposited sediments like alluvium or sand. Regosols are young, weakly developed soils with little to no distinct layering (horizons) and are common in areas of recent geological activity, such as floodplains, dunes, or eroded slopes.
Regosols are classified by soil scientists. The term is used in technical contexts like geology, agriculture, and environmental science to describe a specific soil order in classification systems (e.g., the World Reference Base for Soil Resources). - The river delta is characterized by fertile regosols. - Farmers face challenges cultivating crops in shallow regosols. - The mapping project identified large areas of regosol along the coast.
- As a soil order: In formal soil taxonomy, "Regosol" (often capitalized) refers to one of the 32 reference soil groups in the World Reference Base (WRB) system, denoting soils with very weak development.
- In land use planning: The properties of regosols (e.g., good drainage but low fertility) are critical factors in land capability assessments for construction or agriculture.
- Regosolic (adjective): Pertaining to or having the characteristics of a regosol.
- The regosolic profile showed minimal horizon differentiation.
- Immature soil
- Azonal soil (a broader category including other weakly developed soils)
- Entisol (the approximate equivalent order in the USDA soil taxonomy system)
- Mature soil
- Zonal soil (a soil with well-developed characteristics reflecting the local climate and vegetation)
- Chernozem (a deep, dark, fertile soil with strong horizon development)
- Soil horizon: A distinct layer of soil. Regosols typically lack well-defined horizons.
- Parent material: The underlying geological material from which soil forms. Regosols form directly from unconsolidated parent material.
- Alluvium: Clay, silt, sand, or gravel deposited by flowing water, a common parent material for regosols.
- a type of soil consisting of unconsolidated material from freshly deposited alluvium or sand
