In civil engineering, soil is a naturally occurring, loose/un-cemented/weakly cemented/relatively unconsolidated mineral particles, organic or inorganic in character, lying over the bed rock which is formed by weathering of rocks. The soil profile extends from the soil surface to the parent rock material. Discover (and save!) The illustration below shows a base color applied on paper laid over concrete. It is called top-soil. Retrying. Soil profiles are composed of various layers called soil horizons. Over time, a number of environmental forces act to create distinct layers or horizons parallel to the soil surface. Terra preta owes its characteristic black color to its weathered charcoal content, and was made by adding a mixture of charcoal, bone, broken pottery, compost and manure to the low fertility Amazonian soil. 1. A soil horizon is a layer parallel to the soil surface whose physical, chemical and biological characteristics differ from the layers above and beneath. The layers in a soil profile are called horizons. B HORIZON- This is the layer that we call "subsoil" and it is located just below the A Horizon.

The soil is divided into various different layers top to bottom and this arrangement is termed as the soil horizons. There are three main layers of soil. Depths should be measured in centimetres from the top of the soil (immediately below any layer of leaves or other non decomposed vegetation) to the top limit of each horizon and to its bottom limit. The most common horizons are named by the letters O, A, B, C, and R. They differ in color, texture, thickness, and structure. Thousands of new, high-quality pictures added every day.
