Refers to the downward movement or loss of dissolved or suspended material within soil by leaching (i.e. salts, nutrients and silicate clays. elluviation leaves the topsoil or A horizon and creates the E horizon. Materials accumulate in the zone of illuviation or accumulation in the B horizon underneath the E horizon.
1. Humification. 2. Mineralization. 3. Leaching. 4. Illuviation. 5. Elluviation.
Eluviation is the movement of the particles (such as minerals and organic matter) into lower soil horizons. Then Illuviation is the accumulation of those particles in the lower soil horizons.
1. O - Layers/horizon (organic layer, containing humus). 2. A - Layer/horizon (top soil). 3. E - Layer/horizon (zone of elluviation). 4. B - Layer/horizon (sub-soil). 5. C - Layer/horizon (zone of illuviation/accumulation). 6. D - Layer/horizon (parent materials/bed rocks).

Eluviation is the movement of the particles (such as minerals and organic matter) into lower soil horizons. Then Illuviation is the accumulation of those particles in the lower soil horizons.
The O horizon contains the most organic matter. The O horizon overlies the A horizon which is known as the mineral horizon. O - organic A - mineral E - elluviation B - illuviation C - parent material R - bedrock This is the order in which you will see standard soil horizons.
1. O - Layers/horizon (organic layer, containing humus). 2. A - Layer/horizon (top soil). 3. E - Layer/horizon (zone of elluviation). 4. B - Layer/horizon (sub-soil). 5. C - Layer/horizon (zone of illuviation/accumulation). 6. D - Layer/horizon (parent materials/bed rocks).
