| Abstract |
The area under study represents one of the highly promising
areas for agricultural investment in the Upper Egypt region. The
current work was carried out to investigate the main soil characteristics
that refer to the economical agriculture in some of desert outskirts
adjacent to the utilized area, and it lies at 7km north west of Armant
district, Qena Governorate. To achieve this target, thirteen soil profiles
were selected to represent, the virgin desert outskirt.
The obtained results showed that the proposed irrigation water
resource (amended sewage effluent) was evaluated according to its
suitability degree as (C2-S1), where the ECiw and SAR laying
within the range of 0.75- 3.00 dS/m and < 6.0, respectively. In
addition, although the values of the N,P,K (macronutrients), Fe, Mn,
Zn, Cu, B (micronutrients), Cd, Ni, Pb and Co (heavy metals) are
relatively high than those found in the main irrigation resource in
Egypt (the Nile water), yet their levels are still laying within the
permissible limits for irrigation water. According to the
morphological description, climatic conditions, physical, chemical
analysis and USDA (2010), the studied soils could be classified as: a)
Typic Calcigypsids, coarse loamy or loamy- skeletal, mixed, hyper
thermic; and b) Typic Haplocalcids, Sandy or coarse loamy or loamyskeletal,
mixed, hyperthermic.
The obtained data of parametric evaluation system revealed that
topography, soil texture, CaCO3, gypsum and salinity/ alkalinity are
considered the main limitations controlling soil productivity foragricultural purposes in the studied area, with variable intensity
degrees of moderate, very severe- moderate, slight, slight and
moderate- slight, respectively. Also, the current suitability
assessment of the studied soil profiles indicated that about 3/4 of the
studied area are considered marginally suitable soils and the rest are
not suitable ones. For raising the capability potential of these
soils, soil improvement practices should be carried out such as land
leveling and removing the excess of soluble salts through applying
the leaching requirements under an efficient drainage ditches. Such
agro-management practices can be corrected the ratings of soil
potential suitability classes for the studied soils to be categorized
into two almost equal areas belonging both the moderately (S2) and
marginally (S3) suitable soils.
In spite of some localities (soil sites 1, 2 and 3) showed
moderate levels of N, P, K and Fe according to the critical limits of
nutrients. The majority soils under investigation were suffering from
nutrients insufficient for N, P, K, Fe, Mn, Zn, and Cu at the root
zone. It was note worthy to mention that the threaten their fertile status
is due to coarser in soil texture, weak in soil structure, very low
organic matter content and low soil potentiality for plant nutrients
supplying power that inherited from their origin sediments, as well
as, these soils were not partially capable to retain neither adequate
water nor nutrients for the grown plants.
