From the calculation result of Figure 6, in the action of the eluviation
, [Ca.sup.2+] ions migrated downward.
In addition, N absorption by sugarcane as well as decreased N eluviation
and accumulation in the soil can be achieved with bagasse charcoal use.
The E horizon is a subsurface horizon that has been deposited by the movement of water (eluviation
In contrast to this, the BrownEarth horizon Be with its strongly coagulated fabric does not contain such oriented clay-colloids, which would be a prerequisite for dispersion and transport by the eluviation
On the mountain sides, gradual deforestation resulted in the eluviation
of parts of the area and favoured the growth of more or less dry grassland communities such as Koelerio-Brometum (on steep slopes) or PotentilloBrachypodietum (on less steep slopes).
This loss is called eluviation
. Materials resistant to weathering, such as sand, tend to remain in the A horizon as other materials leach out.
Savannahs with members of the Combretaceae (Terminalia, Combretum, Anogeissus) grow on mesotrophic soils, where eluviation
and illuviation are not so strong.
With increasing soil acidity and stages of eluviation
and gleyification, the accumulation of non-decomposed organic matter constituting the forest floor (exogenous organic carbon) increases considerably.
The dense clay matrix of subsoil is a consequence of pedogenic processes that have transported and packed clay crystals including eluviation
and shrink-swell forces due to dry-wet conditions (Mullins and Panayiotopoulos 1984).
E horizon--Soil horizon caused by deposit of soil due to eluviation
, or erosion due to water movement.
