Abstract EN

In order to implement this research soil profiles selected on a toposequence were systematically collected from different geohorizons.

Results indicated that topographical factors played important roles in determining some soil features such as the depth, texture distribution of CaCO3 and the fertility matter.

The study showed that the soil content of minor element was ranged between moderate to low, and this may be related to the mineralogical composition of the parent rock and weathering status and to the use of these elements by the plants uptake during the long lasting exploitation.

The results also indicated that the decrease of these elements was consistent with the decrease of elevation, such as heading from the slop to the plain.

This probably also due to the relation between the leaching process and topographical position and to a less extend to the pH of the soil.
