Parent Material of Soil Unconsolidated product of weathering from which soil develops is called parent material. Generally there are two groups of parent materials, i.e. sedentary and transported. The transported materials are further subdivided according to transporting agency and place of deposition. Sedentary or Residual The parent material formed in place and still at the original site. Transported The parent material carried and deposited by various transporting agencies. By gravity- Colluvial By water- Alluvial By ice- Glacial By wind- Eolian The nature and properties of parent material together with climate are the most important factors affecting the kind and quality of soils. So to understand soils we must know the source of material, mechanisms of weathering and transporting agencies. Sedentary or Residual Parent Material
