Regosols

Regosols are a soil order in some soil classification systems, particularly those influenced by the Soviet system of soil classification. They are characterized by a lack of distinct horizons, meaning there is little to no differentiation in soil layers. This often results from the soil being relatively young or being formed on unconsolidated parent material such as sand dunes or recent alluvial deposits. Regosols typically have a weak structure and can be susceptible to erosion due to their lack of stability. Their physical properties can vary widely depending on the parent material, ranging from sandy to loamy. Nutritionally, Regosols are generally not considered fertile unless the parent material is rich in minerals. Their agricultural potential is often limited, though they can be managed with appropriate techniques. In many cases, their development is still in the early stages, and they may eventually develop into more complex soil orders over time with sufficient weathering and biological activity. The term "Regosol" is not part of the USDA's Soil Taxonomy or the World Reference Base for Soil Resources (WRB).
