Fallen leaves make up an important part of the horizon of soil?
Soil is composed of organic and inorganic parts. Inorganic is weathered rock. Organic is dead or decaying organisms called humus. Fallen leaves are part of what makes up humus. Fallen leaves (as well as all humus) are found in the "O" horizon as well as the "A" horizon.
Where are you likely to find dark-rich soil in a soil profile?
you are likely to find dark, humus-rich soil in an A-horizon profile because that's where dark soil is found & the composition is the particles of weathered rock materials mixed with humus.
What is vertical section of soil that starts at earth's surface and moves down to the bedrock is called an?
The answer is Soil Profile------------------------------------
What is an pedalfer?
Soil that is characterized by an abundance of aluminum and iron oxides. Pedalfers are common in humid regions and are deposited in the B horizon of ABC soils, through leaching
What part of the soil consists of decaying organic matter?
The top soil. the decaying material is called humus (NOT hummus!).
What is a cross section in soil called?
A profile is a cross section in soil.
Which soil horizon is the most important agriculturally?
The A horizon as it consists of mainly organic matter.
What is the difference between soil horizons?
Considering that these horizons are in order from top soil to unconsolidated bedrock, usually, a soil profile will have the Organic horizon, the A horizon, the B horizon, the C horizon, and the R horizon.
The section of the soil profile that contains the organic components of soil is?
A-Horizon
The section of the soil profile that contains the organic components of soil?
the A Horizon
What is the section of the soil profile that contains the organic components of soil?
B-horizon
What kind of soil is found in the A horizon of a soil profile?
The C horizon is based on bedrock. No soil is present that means that it is a layer of no penetration and usually consists of solid rock foundation.
What is the difference between soil profile and soil horizons?
A soil profile is the section of soil going down vertical, while soil horizon is the section of soil going horizontal.
What is a vertical cross section of the soil?
Soil profile
Which soil horizon is the lowermost?
Bedrock is the lowest soil horizon that you will find. This is the area that consists mainly of solid rock that has been formed by many years of compression placed on the above layer of soil.
The section of the soil profile that lies directly above the bedrock?
c-horizon
Which horizon of soil is the parent soil?
THe c horizon
