AVTP affects soil properties by accelerating the weathering and eluviation of rocks, whereas AVPR leads to soil eluviation.
Depending on the composition of parent materials of soils (geodiversity) and water conditions in the soil covers of the studied EAs, the processes of argillization, eluviation, podzolization, gleyification and paludification are taking place (GSE 1999; Reintam 2002).
Finally, the solutes migration rule of the soil subjected to the atmosphere eluviation is revealed, and the reasonableness of the coupling model and the finite element method is proved.
Podzols of forest-tundra were sampled from all soil horizons because of the possible redistribution of organic matter due to eluviation processes.
This result is related to the Ordovician surface uplift, the overall open environment, meteoric water eluviation (Land, 1980; Rosen et al., 1989; Gasparrini et al., 2006) of widespread [delta][sup.12]C, and all [[delta].sup.16]O of atmospheric C[O.sub.3] [sup.2-]sources (Veizer et al., 1999; Azmy et al., 2009).
The predicted texture patterns can be interpreted as catena sequence, resulting from down slope eluviation of fine grain sizes initiating at the slope shoulder.
In addition, bagasse charcoal use increased N absorption for sugarcane and N accumulation in the soil, along with decreased N eluviation. Therefore, we conclude that bagasse charcoal reduces N loads in Shimajiri maji soil.
