What else can I help you with?
In a well developed soil profile which horizon is the uppermost layer?
The uppermost layer in a well-developed soil profile is the O horizon, also known as the organic horizon. This layer consists of organic matter such as decaying leaves and plant material. It is typically found at the surface of the soil profile.
What layer in the soil does leaching occur in?
Leaching typically occurs in the topsoil layer of the soil profile. This is because the topsoil is the uppermost layer where organic matter and nutrients are present, making it susceptible to leaching when water percolates through it.
What is the A horizon known as?
The A horizon is known as the topsoil layer of soil. It is the uppermost layer where most organic matter and nutrients are found, making it crucial for plant growth and agriculture.
What kind a material is found in the C horizon of the soil profile?
Partially weathered parent material is found in the C horizon of a soil profile.
A layer in the garden soil profile with seven letters?
Horizon.

Is horizon a on top or is horizon b on top?
The terms "horizon a" and "horizon b" typically refer to layers in a soil profile or stratigraphic sequence, with "horizon a" often representing the uppermost layer, such as topsoil, while "horizon b" is usually a deeper layer beneath it. Therefore, horizon a is generally considered to be on top of horizon b. However, the specific context may vary, so it's essential to clarify the definitions being used in each case.
Which layer in a soil profile contains the most organic matter the A horizon or O horizon?
It is the O horizon. The A horizon is the mineral horizon and does include a large amount of organic material but the O horizon contains the most abundant amount of organic matter. The O horizon overlies the A horizon.
What kind a material is found in the C horizon of the soil profile?
Partially weathered parent material is found in the C horizon of a soil profile.
A layer in the garden soil profile with seven letters?
Horizon.
What is the layer where the A B and C horizons sit?
The A, B, and C horizons are found within the soil profile, which is composed of different layers of soil. The A horizon, also known as the topsoil, is the uppermost layer rich in organic material and nutrients. Below it is the B horizon, or subsoil, which accumulates minerals leached from the A horizon. The C horizon consists of weathered parent material from which the soil develops, providing the foundation for the upper layers.
Which layer of a soil profile forms first from the bedrock?
The C horizon is the layer of a soil profile that forms first from the bedrock. It is the underlying layer that contains weathered rock fragments and shows the least amount of soil development.
What part of the soil is formed by the decaying plant and animal remains?
The uppermost layer of the soil which is the O-horizon, and is called "Humus".
Which soil layers comprise the topsoil?
Topsoil typically consists of the uppermost soil layers, including the O horizon (organic matter layer) and the A horizon (mineral layer). These layers are rich in nutrients and organic matter, making them essential for plant growth and agriculture.
Which is the second layer of a soil profile?
The second layer of a soil profile is called the B horizon. It is located beneath the topsoil (A horizon) and is often characterized by an accumulation of minerals leached from the topsoil above. The B horizon typically has a higher clay content and can also contain iron or aluminum oxides.
