OBJECTIVE FORESTRY

Detailed explanation-1: -Some of the clay thus formed tends to migrate downward, along with other transportable materials (such as soluble salts). The clay tends to accumulate in an intermediate zone (called the B horizon) between the surface zone of major biological activity and the deeper parent material of the so-called C horizon.

Detailed explanation-2: -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-3: -The C horizon is the layer below the B horizon and above the R horizon. It is also called as regolith. It consists of slightly weathered rocks, roots of the plants cannot penetrate in this layer.
