The A horizon, or topsoil, is the uppermost layer of soil where organic matter accumulates and roots grow. It is rich in nutrients and humus, making it an ideal zone for plant growth. This layer is important for agriculture and ecosystem health.

Name All the horizons of a soil?

The horizons of a soil profile are O horizon (organic matter), A horizon (topsoil with organic material), E horizon (zone of leaching), B horizon (subsoil with accumulation of minerals), C horizon (weathered parent material), and R horizon (bedrock).


What is the difference between illuviation and eluviation?

When talking about soils, soils are typically divided into various horizons depending on what layers are present. The horizons include in this order: O Horizon <---- (Organic Horizon) - This is the top soil where plants grow. A Horizon B Horizon C Horizon Bedrock <---- This is lithified material. This means that there is no longer any lose soil at this point, and it has been turned to rock by pressure of overlaying sediment or other geological processes. Eluviation occurs in the E Horizon. The E Horizon is also known as the Zone of Leeching. By definition, eluviation is the process of removal of materials from geological or soil horizons. Essentially, this is where most of the weathering occurs in the soil. Illuviation occurs in the B Horizon. The B Horizon is also known as the Zone of Accumulation. By definition, illuviation is the deposition in an underlying soil layer of colloids, soluble salts, and mineral particles leached out of an overlaying soil layer. In layman's terms, this is where the particles end up in the B Horizon after they are weathered from the A Horizon.


Which layer of soil are the materials leached from horizon A deposited?

Materials leached from horizon A are typically deposited in the B horizon of the soil profile. As water moves through the soil, it carries minerals and nutrients from horizon A and deposits them in the B horizon.


What is the correct order of the different soil horizons?

The correct order of soil horizons, from top to bottom, is O horizon, A horizon, E horizon, B horizon, C horizon, and R horizon. It is important to note that not all soils have all these horizons, as they can vary depending on the specific conditions of the soil.


Where in the soil profile is solid is solid rock being weathered into soil?

Solid rock is being weathered into soil in the parent material layer or C horizon of the soil profile. This is where the physical and chemical breakdown of the rock material occurs, leading to the formation of soil.

Which soil layers comprimise soil layers?

Soil layers are called soil horizons. Typically, a soil includes an A horizon, a B horizon and a C horizon. In laymen's terms: A horizon = topsoil B horizon = subsoil C horizon = parent material (the stuff in which the soil formed)
