The Unified Soil Classification System (USCS) is a soil classification system used in engineering and geology to describe the texture and grain size of a soil.The classification system can be applied to most unconsolidated materials, and is represented by a two-letter symbol. The organic soils are further classified as organic soil of low plasticity (symbolized as OL), organic soil of high plasticity (symbolized as OH) and Peat (symbolized as Pt).
