Soil Profile It is a vertical section through various layers of soil. These various layers areknown as horizons.There are four types of horizons :-
  1. A-horizon or topsoil It is the top most soil, which is dark in colour and rich in humus. It is soft, porous, and has the ability to retain water.
  2. B-horizon It is the middle next layer of the soil profile. It has lesser humus and moreminerals. The layer is harder and more compact.
  3. C-horizon It is the third layer made up of small lumps of rocks with cracks andcrevices.
  4. Bedrock It is the lowermost hard layer and difficult to dig with a spade.

Dear Friend,

Soil profile

The vertical section of soil from the surface down to bedrocks, showing different horizons, is called soil profile. The soil profile shows three layers one above another.

  1. A-horizon A-horizon consists ofthe topmost layer of the soil that contains minerals, nutrients, and humus in addition to the soil particles. It is also known as topsoil. It is the most fertile part of the soil, which is rich in humus and has good water holding capacity.
  2. B-horizon It lies below A-zone and is called subsoil. It consists of sand, silt, and clay. It is hard and compact and is rich in minerals such as iron oxide.
  3. C-horizon It lies under subsoil and has parent rocks. The layer of large solid rocks, called the bedrock lies below this layer. It is an impermeable layer over which rain water collects and forms the base of the water table.

Hope it is informative:-)
