Question

Sketch the cross-section of soil and label the various layers?

Answer 1

Soil profile:

1. Vertical cutting of different layers of soil is called a soil profile.
2. Each layer has a different feel, color, depth, and chemical composition. These layers are referred to as horizons.
3. As a result of its abundance of humus and minerals, the topmost horizon (A horizon) is often dark in appearance.
4. A horizon is porous and soft, and it may hold more water.
5. It provides shelter to several organisms such as rodents, beetles, etc.
6. B horizon or the middle layer is the next layer after A horizon.
7. B horizon has less humus but more minerals, more complex and compact.
8. The third layer is the C horizon.
9. C horizon comprises small lumps of rocks with cracks and cerevisiae.
10. Below the C horizon, Bedrock is present that is hard and difficult to dig with a spade.
