ABSTRACT
This research aims to know the behavior of some microelements and
relation to their geomorphological units in the far western soils of Minya,
Egypt. Achieve this were collected twenty two samples of eight soils
profiles in different locations at Far-West of El-Minya - Egypt. In this area,
one of the huge national projects that the Egyptian governments. The
obtained results showed that, the levels of available Fe, Mn, Zn, Cu, Ni, and
Cr were oscillated closely to the critical levels of international regulation.
The correction between the studied heavy metals and both soil physical and
chemical properties tended to be oscillated from element to another.
The concentrations of available Fe was higher than the critical levels
of 2.5-2.6 mg kg-1 except for the first layer of soil profile number 1. The
Critical values of Mn in both sandy and calcareous soils were set to be 1.4
and 1.2 mg kg‐1, respectively and accordingly, the concentrations of Mn in
the studied soils profiles were lower that the critical levels particularly for
soil profiles number 1 and 2. However, it was close to the critical levels in
the rest of soil samples. Comparatively, high levels of Mn were observed
with the deep layer of soil profile number 3 and the top layer of soil profile
number 4. As it has set previously by different studies, the critical levels of
Zn in the alluvial and calcareous soils were 0.9 and 0.7 mg kg‐1,
respectively, samples that collected from soil profiles one and four were
lower than or equal to the critical levels. The concentrations of available Cu
in our study were oscillated among high to medium critical levels.
