What Horizon has the highest amount of organic material?
A horizon B horizon C horizon O horizon
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
What is the B horizon?
The B horizon is the layer of soil underneath the A horizon, which is under the O horizon. The B horizon contains minerals and sand grains as well as organic material. If you didn't get it when your teacher explained it, ask him/her aboput it. They are sure to explain better than I can!
Which layer in soil contains the most organic matter?
the layer the contain the richest material is the top soil :)
What kind of material is found in the C horizon of a soil profile?
The A horizon in soil is typically made up of mineral and organic material. In some instances the A horizon is only 2 to 3 inches deep, although it can be much deeper if the land has been plowed.
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.

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 the B horizon?
The B horizon is the layer of soil underneath the A horizon, which is under the O horizon. The B horizon contains minerals and sand grains as well as organic material. If you didn't get it when your teacher explained it, ask him/her aboput it. They are sure to explain better than I can!
Which layer in soil contains the most organic matter?

Why is it that A horizon contains more organic mater than B horizon?
Because the A horizon contains more humus which makes the A horizon more organic
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 kind of material is found in the C horizon of a soil profile?
The A horizon in soil is typically made up of mineral and organic material. In some instances the A horizon is only 2 to 3 inches deep, although it can be much deeper if the land has been plowed.
Five things about the make up of soil?
Soil is composed of five distinct horizons. In order from closest to the surface to farthest away from the surface, they are: the O Horizon, A Horizon, E Horizon, B Horizon, and C Horizon. The O Horizon - or "organic" horizon, is composed mainly of loose and partly decayed organic matter such as leaves and teems with microscopic life. The A Horizon is mineral matter mixed with some humus (the decayed remains of animal and plant life). Together, the O and A Horizons make up what is known as topsoil. Below the A Horizon is the E Horizon, which is made up of light colored mineral particles. It contains little organic matter. The B Horizon is an accumulation of clay transported from above as water percolates through the upper horizons. The B Horizon is also known as "subsoil". The O, A, E, and B Horizons are collectively called "Solum", or "True soil". The C Horizon is partially altered parent material. Although this material is undergoing changes that will eventually turn it into soil, it still possess most of the characteristics of the bedrock underneath and has not crossed the boundary that separates regolith from soil.
Where in the soil profiles is organic matter broken down?
the A horizon
What does the O in the O horizon refer to?
The "O" in O horizon stands for "Organic"
