This vertical distribution pattern can be explained by chemical
eluviation due to water flow in the soil profile.
This result is related to the Ordovician surface uplift, the overall open environment, meteoric water
eluviation (Land, 1980; Rosen et al.
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.
No evidence of
eluviation was found yet in our sites.
In addition, bagasse charcoal use increased N absorption for sugarcane and N accumulation in the soil, along with decreased N
eluviation.

What is the difference between
eluviation and illuviation?
In the topsoil moder changes into raw humus (Orm) and in the sour A-horizon As
eluviation begins by podzolization: AsEp (not so clearly visible in the photo).
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).
E The E horizon, the zone of greatest
eluviation, is very leached of clay, chemicals, and organic matter.
Savannahs with members of the Combretaceae (Terminalia, Combretum, Anogeissus) grow on mesotrophic soils, where
eluviation and illuviation are not so strong.
