OBJECTIVE FORESTRY

Detailed explanation-1: -Bedrock is also known as parent rock and lies just below the subsoil. It contains no organic matter and made up of stones and rocks, so it is very hard. This layer represents a transition zone between the earth’s bedrock and horizon A and B.

Detailed explanation-2: -C horizon. noun. the layer of a soil profile immediately below the B horizon and above the bedrock, composed of weathered rock little affected by soil-forming processes.

Detailed explanation-3: -D Horizon (Bedrock) – This layer is comprised of consolidated rock (tight, unbroken, large formations of rock). There is very little organic material and roots do not dig down this deep. Note – As you can see, the soil layers gain stability as you go down. Bedrock can be anywhere between 7 and 150 feet deep.

Detailed explanation-4: -C Horizon is also called regolith. This is the layer beneath the B Horizon and above the R Horizon. It consists of slightly broken-up bedrock. Plant roots do not penetrate into this layer; very little organic material is found in this layer.

Detailed explanation-5: -C Horizon-The C-horizon is a layer of partially altered bedrock. There is some evidence of weathering in this layer, but pieces of the original rock are seen and can be identified.
