OBJECTIVE FORESTRY

Detailed explanation-1: -The soil is arranged in layers or horizons during its formation. These layers or horizons are known as the soil profile. It is the vertical section of the soil that is exposed by a soil pit. The layers of soil can easily be identified by the soil colour and size of soil particles.

Detailed explanation-2: -Soil horizon R is made up of bedrock. The rocks typically found in this layer include limestone, quartzite, sandstone, basalt, and granite. In areas where the bedrock is exposed at the surface of the ground, these materials will weather. The materials that weather off of the bedrock become the soil horizon C.

Detailed explanation-3: -The E horizon is not present in all soil profiles and can be found on sites with a high temporary water table or forest soils. The B horizon, or subsoil, is referred to as the zone of accumulation due to buildup of minerals leached out of the A and E horizons. This leaching process is known as illuviation.

Detailed explanation-4: -The soil is found in layers, which are arranged during the formation of soil. These layers called horizons, the sequence of layers is the soil profile. The layers of soil can easily be observed by their color and size of particles. The main layers of the soil are topsoil, subsoil and the parent rock.

Detailed explanation-5: -The topsoil, subsoil and parent material.
