Where in the soil profiles is organic matter broken down?
the A horizon
Which layer in soil contains the most organic matter?
the layer the contain the richest material is the top soil :)
What are the layers of soil and its description?
O-Horizon: leaf litter, organic material A-Horizon: plough zone, rich in organic matter B-Horizon: zone of clay, iron and organic matter C-Horizon: weathering zone, little organic matter and little life R-Horizon:unweathered parent materia
Why is top soil horizon so dark?
Topsoil has more organic matter in it than the rest of the soil. Decomposed organic matter (humus) is usually dark brown or black.
Which soil horizon is the most important agriculturally?
The A horizon as it consists of mainly organic matter.
Which layer in a soil profile contains the most organic matter the A horizon or O horizon?
The O horizon contains the most organic matter in a soil profile. It is the top layer of organic material such as decaying leaves, branches, and other plant debris that is actively decomposing. The A horizon, also known as the topsoil, is a layer rich in minerals and organic matter that is developed from the decomposition of plant material in the O horizon.
Where in the soil profiles is organic matter broken down?
the A horizon
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.

Where in the soil profile organic matter broken down?
the A horizon
Where in this soil profile are worms and insects vreaking down organic matter in the soil?
A horizon
Where in the C horizon is organic matter broken down?
The upper layer is the part of the C soil horizon where organic matter is broken down. The C horizon may be described as soil among the rocks, as opposed to rocks among the soil characteristics of the overlying A and B horizons. It receives the name regolith because of the preponderance of non-organic matter.

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.
What soil best describes the A soil horizon?
Organic loam.
