OBJECTIVE FORESTRY

Detailed explanation-1: -This layer is devoid of any organic matter and is made up of broken bedrock. This layer is also known as saprolite. The geological material present in this zone is cemented.

Detailed explanation-2: -R (bedrock): A mass of rock such as granite, basalt, quartzite, limestone or sandstone that forms the parent material for some soils – if the bedrock is close enough to the surface to weather. This is not soil and is located under the C horizon.

Detailed explanation-3: -The deepest soil layer, the C horizon, consists of decomposed rock, parent material that has characteristics of the subsoil above it and the bedrock beneath it.

Detailed explanation-4: -R horizons denote the layer of partially weathered or unweathered bedrock at the base of the soil profile. Unlike the above layers, R horizons largely comprise continuous masses (as opposed to boulders) of hard rock that cannot be excavated by hand.

Detailed explanation-5: -Notes: R-Horizon is also known as bedrock, this forms the bottommost layer of the soil profile. It comprises of largely unbroken rock strata, as a continuous hard mass. In situ, soils exhibit many features of the bedrock strata.
