A complete soil profile contains six basic layers, which each layer represented by Here is your sample essay on Soil K. Raja The vertical section of the soil from A horizon to the bed rock is called soil profile.
While in residual soil a horizon may just overlie its bed rock same may not be true in case of drift (alluvial) soil. The Soil Profile: (400 Words) The layering or horizon development described in the previous section gradually gives rise to natural bodies called soils. Each soil is characterised by a given sequence of these horizons. Soil profile is the vertical section of soil showing the various layers from the surface to the unaffected parent material.
The soil contains three main layers. The surface soil or that layer of soil at the top which is liable to leaching and from which some soil constituents have been removed is known as horizon A or the horizon of eluviation. Soil Soil is a natural body consisting of layers (soil horizons) of mineral constituents of variable thicknesses, which differ from the parent materials in their morphological, physical, chemical, and mineralogical characteristics.
[1 Soil profile is a vertical section of soil through all its horizons and it extends up to its parent materials. The horizontal layers in a soil profile are called horizons. Solum AB horizons The soilprofile consists of two or more horizontal layers, called horizons.

It is made up of a s The soil profile is composed of horizons (horizontal layers of soil) which may be characterized by physical, chemical, and biological properties.
Horizons may be divided into major categories corresponding to the surface soil (O and A horizons), the subsurface soil (E and B horizons), and the substrate (C and R horizons). Essay The soil profile can be broadly divided into five horizons. From the surface downwards, these may be named as Ohorizon, Ahorizon, Bhorizon, Chorizon and Rhorizon.
The A and B zones together form the true soil or solum.
