  Soil Profile The vertical and sequential arrangement of soil layers superimposed one above the other from the top surface to the unaffected rock below is termed as soil profile. The individual layers constituting the soil profile are called soil horizons. For instance, if we cut a vertical section of soil at a particular place, we clearly see different soil layers or horizons from top mature soil to the rock below. These horizons are formed through the differential downward movement of various materials such as organic matter, clay particles etc. moreover soil horizons vary in properties like colour, texture, structure, thickness, chemical composition, mineral content, consistency and reaction. In general soil profiles tend to become thicker, deeper and more altered over time. Soil profile can be as little as 10cm thick in immature soils and as deep as several meters in tropical areas. Soil profile is considered as one of the most important key factor for understandin...
