What is eluviation and in which layer is this most likely to occur? (2024)

Eluviation:

1. Eluviation or leaching is the process of removing materials from geological or soil layers.
2. Eluvium, also known as fluvial deposits, are geological deposits and soils formed by weathering combined with gravitational movement or accumulation.
3. Eluviation and illuviation occur simultaneously.
4. Eluviation involves the removal of nutrients and organic material from superficial horizons.
5. While illuviation involves the deposition of these nutrients and organic materials in deeper horizons, forming horizons in organic materials.
6. The superficial layer of the soil is likely to be involved in the eluviation process.
