Erian, Wadid 
The result of the effective soil depth interpolated map was compared with the uncultivated area of the 
spectral classification, after, Erian, et al (1999) and also with the soil map for acceptability as presented in 
Map ( 7) and Table (5). The classification of the interpolated maps were rated in five classes and presented 
as in Maps (8,9, and 10).
