Understanding Soil Horizons

The video explains the concept of soil horizons, which are layers that form in soil over time. It describes the three main horizons: A, B, and C. The A horizon, or topsoil, is rich in nutrients and humus. The B horizon, or subsoil, is lighter and contains fewer nutrients, with minerals leaching into it. The C horizon consists of partially weathered rock, similar to the underlying bedrock. The video concludes by noting that soil profiles vary greatly depending on location.
