Does subsoil contain more organic matter than topsoil or parent rock?
yes
Does subsoil contain more organic matter than either topsoil or parent rock?
yes
What are the horizons of the soil?
O-horizon (surface litter)=mainly partially decaying organic matter A-horizon (Topsoil)= mainly contains organic matter, living organisms, inorganic minerals. E-horizon (Eluviated zone)= low quantities of minerals,clay and organic matter due to leeching. B-horizon (Subsoil)= accumulation of iron, aluminium and clay leached down from the A and E horizons. C-horizon (Regolith)= partially broken down inorganic minerals Bedrock
What is the layer of soil with little or no organic matter?
subsoil
What an important part of topsoil?
decayed organic matter

Is subsoil best for growing crops?
No. Subsoil is the layer of soil beneath the topsoil, which is the best for growing crops. Subsoil, depending on the soil type, is usually where the finer mineral commponents lie, such as clays or calcic materials. They usually have little or no organic matter content, and can be somewhat impermeable to water and plant nutrients. Some shallow soils even have bedrock as one component.

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.
What is deeper bedrock or humus?
Bedrock. Humus is decaying organic matter, and most organisms live above bedrock.
What type of soil that contains a large amount of organic matter?
Topsoil has the greatest amount of organic matter
