LAND SUITABILITY EVALUATION OF’ EL-SAFT
MEA EASTERN DESERT , EGVPT FOR AeRIaL TURE UTILIZATION The studied area is a part of El-8aff district. It
is located
o
1titude 31

and 30
in the eastern desert of Egypt,
o
and 32 10 N, and longitude
between
o -
30 29 30
E. The geology of the studied area is
is character ized with exposure of
of .•o.c.k& belonging to the Holocene, Pleistocene
and Middle Eocene soils. The area is characterized
by a hot rainless summer, mild winter with low .•.i.n•-
fall. The studied a.•e.a. is nearly flat with a gentle
natural slope from contour +169 to contour +44. In the
.>:
north, the land surface is almost poor of vegetation
except scarcty dese .•t..genes. Desert pavement is p.•e.s.ent
eve .•y.w.he .•e..except in wadis and in areas wadi-blown sand
No plants can survive on the coarse desert paveaent,
provided by dew.
The 50il .u.•v.e.y of the study area has b.en undertaken
using .•.~.t•. sensing technology to p.•o.v.ide a
a .•e.l.ativ.ly rapid and accu .•.t.e• a••••• -.nt regardless
of the problems of traversing it on the ground.
The used VIEWS 100 digital image analysis system
facilitates the processing of the Computer Compatible
Tape (eel>, recorded on 1 may 1978 by Landsat - 3 MSS,

The digital image
the following steps to
studied area:
enhancement proceasing include

1~ Histogram equlization.
2~ Supervised classification of Maximum likelihood
3~ Supervised classification of parallelpiped.
4. Supervised statistical classification.
Land units were established using the parallelepiped
classification, as well as the descriptor of the
six .pec~ral classes for the saMple area. The total
pixels covering the sample area are approximately
67591 representing 72322 faddans out of a total
area of 350618 faddans. The descriptions of th•••
six classes as follows,
1. Wadi bottom; haVing an are. of 915 faddans.
2. Wadi plain; 15209 faddans.
3. Terraces; 32465 faddana, including:

II. The terrace. gently undUlating, 8555 faddans.
III. The Rubble terraces, 7470.74 faddans.
4. Flat alluvial basin. having on area of 23734 faddans.
from field observations, thirteen soil profiles
representing the studied area were selected Morphological
description 01 soil profiles were performed as
well as complete laboratory analyses of soil samples.
The soil classification was carried out to the
series level exhibited thirteen soil series representing
two soil orders. These series are composed ••• entially
of sand textured soils. Their surface is
covered with many fine and medium gravel.
The data required by different land suitability
evaluation systems compatible with an arid and
.emi-arid regions, inclUded,
1. Qualitative systems.
I. USDA Land Capability Classification.
II. FAD Land SUitability Evaluation.
2. Quantitative .yst ••••

In ConclusionRemote sensing techniques, that could be considered
a. a good tool for soil survey, was followed, to
study the area located in EI-Saff area, Giza govarnorate.
The parallelpiped classification method used
for identifying the physiographic units dominating in the
in the studied area.
The studied area could be classified as follows:
A. The area SUitable for agriCUltural utilization
1. Using the USDA system, an area equals 63938
faddans, representing 88.40y’ of the stUdied
area, is suitable.
2. Using the FAD system an area equals
63937 faddans
8B.40Y. from
the stUdied area is SUitable.
3. Applying Storie Index the suitable area
equals 23734 faddans representing 4~.9 y.
from the studied area.
4. Applying SY. and Verhey., an area a~unting
to 28011 faddans, representing 52.3 X
B. The non suitable order;
The non SUitable ar.a recorded with the different
systems can be .~rized as follows:
- 5 -
1. Using USDA this area equals 8386 faddans
representing 11.6X of the studied area.
2. Using The FAO,the nonsuitable area equals
8386 faddans representing 11.6X of
the studied area.
3. APPling Storie Index an area equals 48589
faddans representing 54.1 X from the
stUdied area is non SUitable.
4. Appling SYs and Verheye an area
44311 faddans representing 47.7,.
stUdied area is not SUitable.
C. ReSUlts may suggest that the quantitative systems
more SUitable under the EgyPtian conditions,
where their reSUlts are compatible With
the stUdied are. conditions.
D. Storie index and Sy. ~ Verheye, are could be
considered as favorable systems under the
conditions prevailing in the SOils of Egypt.
