The Pedological Aspectes for soils of some Wadis in Southern Sinai, Egypt
|
|
Abstract: The aim of the current study is to evaluation of morphological of soils at some Wadis in Southern part of Sinai. Classification and quantitative Land evaluation of these soils will be also carried out. Accordingly suitable suggestion could be attained to help in planning the reclamation process and to the understanding how to deal with these soils for agricultural use.
Fourteen soil profiles were selected at different contour lines representing the three main wadis (Wadi El-Murr, Wadi Wardan and Wadi Gharandal) in southern west of Sinai Peninsula. Morphologically described and sampled. Also site characteristics were observed and registered.
The important morphological properties were used for evaluating the pedological development. Soil chroma-test procedure was achieved for surface layers of some soil profiles. Studied soils were classified and the soils were evaluated using two systems for land evaluation namely, the Land Capability Classification, and the Soil Suitability Classification.
The results reveled that :-
• The values of RHD for the studied profiles of Wadi Gharandal have the lowest RHD ratings, indicating slight horizontation or differences between the horizons compared with the profiles representing Wadis El-Murr and Wardan.
• Studied profiles in Wadi Gharandal area have the low RPD ratings. This indicates that the soils of Wadi Gharandal are lower pedological development than the other studied soils in other studied Wadis.
• Chroma-test figures of the surface layer of some studied profiles revealed that these soils have weak structures, very bad air-water relationships, no or very weak microbial activity, very bad biological situation no possibility for humus building, very poor and very low productively. These soils necessarily need reclamation with addition of chemical and organic fertilizers.
• Generally, the most soils in studied Wadis are classified under Aridisols.
• Land capability index values indicated that the studied soils belonging to III, IV and V grades. The soils of studied Wadis are placed at marginally (S3) and moderately (S2) suitable for most used growing crops, the soils are very suitable (S1) and/or moderately (S2) for olives
