Abstract

The current investigation was carried out to evaluate the existing of hardly
reclaimable soils suffering from salinity. sodicity and heavy metals pollution in Egypt.
Thirty scil profiles were studied in fIVe different locations. Such locations have been
irrigation for long period with drainage and waste water.
The results come out the limits of salinity (ECe) ( 9.04 to 21.47 dS/m) and
sodicity (ESP) (25.53 to 47.71 %). which mean that the problems of salinity and
sodicity are found in these locations. In addition. Ihe soil samples containing high
levels of some heavy metals such as Cu. Pb. Cd, Ni. Co and Zn. The determined
levels are higher than the pennissible limits as reported by linzop (1987). II can be
concluded that there are scattered areas all over Egypt suffering from two different
problems which make it difficult to be reclaimed.
