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.


Which horizon of the soil contains the most organic material?

The O horizon, also known as the organic horizon, contains the most organic material. It is made up of decomposing organic matter like leaves, plant debris, and other organic materials.


Which soil horizon is chemically most similar to the underlying bedrock or unaltered sediment?

The parent material horizon, also known as C horizon, is chemically most similar to the underlying bedrock or unaltered sediment. This horizon is largely unaffected by the processes of soil formation and represents the original material from which the soil developed over time.


What layer of soil contains the most decayed material?

Which layer in a soil profile contains the most organic matter?

The O horizon contains the most organic matter. The O horizon overlies the A horizon which is known as the mineral horizon. O - organic A - mineral E - elluviation B - illuviation C - parent material R - bedrock This is the order in which you will see standard soil horizons.


Weathering occurs most rapidly in what horizon?

What are the three horizon of a mature residual soil?

The three horizons of a mature residual soil are the A horizon (topsoil), B horizon (subsoil), and C horizon (weathered rock material). The A horizon contains organic matter and is the most fertile layer for plant growth. The B horizon is rich in minerals leached from the topsoil. The C horizon is the least weathered and consists of partially weathered bedrock.
