A is the layer of the soil profile in which most organic material is found.Specifically, there are five layers in the soil profile. The first, A layer of organic matter claims the first two inches and contains plant debris. The second, A layer of surface soil comprises the next ten inches down. Below it will be found the third, B layer of subsoil containing aluminum, clay, iron and organic compounds and going down 30 inches; the fourth, C layer of parent rock going down 48 inches; and the fifth, final, R layer of bedrock.

Top soil
It is called soil.
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.
The organic material in soil is humus.
Organic Layer - plant litter Surface Layer - mineral and organic mixture Subsoil - contains clay, iron, aluminium Substratum - parent material
Soil is not fabricated...nor is any organic material.
there is the organic layer which is the top most layer and its about 8cm deep
