soilhorizon
A soil horizon is a layer of soil that has distinct characteristics, such as color, texture, structure, and composition, which differ from the layers above and below it. Soil horizons are typically identified by their depth and the processes that have shaped them. The most common soil horizons are:
1. O horizon: This is the topmost layer, composed of organic material such as leaf litter, peat,
2. A horizon: Also known as the topsoil, this layer is typically dark in color due to
3. E horizon: This layer is often found in grasslands and is characterized by the leaching of
4. B horizon: This layer, also known as the subsoil, is typically lighter in color than the
5. C horizon: This layer is composed of weathered parent material, such as rock or sediment, and
6. R horizon: This is the bedrock layer, which is the parent material from which the soil
Soil horizons are important for understanding soil formation, nutrient cycling, and plant growth. They are typically
