What is an A horizon layer?
A soil horizon is a layer parallel to the soil surface whose physical, chemical and biological characteristics differ from the layers above and beneath. Horizons are defined in many cases by obvious physical features, mainly colour and texture.
Feb 17, 2023 · Soil Horizons Layers Diagram Chart. What is Soil Horizon? During its formation, the soil is arranged in different layers. Each of these layers is called a soil horizon, and when these layers are arranged sequentially one above the other, it forms the soil profile.
The A horizon, or topsoil, is the upper layer of soil in which plants have most of their roots. It has a high concentration of organic matter and microorganisms. So, this layer and the O horizon are often the most nutrient-rich and productive layers in a soil profile.

- Yes. Mostly desert directly starts from the B horizon.

Soil Horizons. Soil Profile. All soils have different types of layers. There are different types of soil, each with its own set of characteristics. Dig down deep into any soil, and you’ll see that it is made of layers, or horizons (O, A, E, B, C, R). Put the horizons together, and they form a soil profile.
Within the soil profile, soil scientists define zones called horizons. A horizon is a soil layer with distinct physical and chemical properties that differ from those of other layers. Five factors account for soil formation: parent material, climate, topography, biological factors, and time.
Jun 5, 2023 · The A Horizon is a well-weathered and fertile layer dominated by mineral particles but still rich in organic matter, especially if covered by an O Horizon, which can leach decomposed organic matter into the A Horizon.
