Is there humus in the C horizon of soil?
no it is found in the topsoil or a horizon
Why is the A horizon the most evolved soil layer?
Well, the A horizon is made up of topsoil, a crumbly, dark brown soil composed of humus, clay, and other minerals.
Which horizon contains the most humus?
soils have different layers present in it as the depth increases. These layers are called horizons. Humus as we all know is present in the top layer of the soil,which is several inches in thickness and is called A horizon.
Which soil layer contains the least humus?
The C and R horizon
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.
Which soil layer contains the most humus?
the O-Horizon is the topmost soil so it has the most humus
How leaching effects soil?
In soil, water seeps through the A horizon and reacts with humus and carbon dioxide to form acid .
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".
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.
Which contains the most humus?
soils have different layers present in it as the depth increases. These layers are called horizons. Humus as we all know is present in the top layer of the soil,which is several inches in thickness and is called A horizon.
Which layer of soil is the most newly formed?
Humus
Which biome soil is rich in humus?
AnswerThe O horizon and the A horizon are most rich in humus due to the organic material being highest in those two layers. O is higher than A, though. mjhgbb
