PEDOLOGICAL STUDIES ON THE REGION OF EAST OF OWYNAT
HASSAN ESMAIL MOHAMED ELSAYED;
Abstract
The studied area lies between longitudes 28° 32' and 28° 38' east, and latitudes 22° 41' and 22° 46' north in East El-Oweinat region, and it has great amounts of best quality ground water. So, the current study aims to give an scientific idea about the importance of soil characteristics, potentialities and suitability for certain crops at the studied area, as well as the giving suitable recommendations for a successful agriculture utilization.
I) Soil texture ranges between slightly gravelly loamy sand and extremely gravelly sand.
2) Soil bulk density ranges from 1.69 and 1.94 g.cm-3, and has either positive and significant correlation with both sand and gravel or negative and significant correlation with both clay and silt.
3) Values of both hydraulic conductivity and infiltration rate vary between moderately rapid and rapid, indicate that their affecting positively and significant with sand and gravel constants.
4) The moisture constants, i.e., field capacity, wilting point and available water, as well as, pore size distribution are more affected by the skeletal nature of the studied soils.
5) The soils appear not saline or sodic category, soluble Na+
> Ca++> Mg++> K+ and Cr> S04-- > HC03-
6) Total carbonate ranges widely between 0.22 and 26.46%.
7) Gypsum and organic matter contents are found in low values of 1.0- 1.34% and 0.01 - 0.07%, respectively.
8) The soils of the studied are classified into six taxonomic units (family level) as follows:
