INTRODUCTION

The increasing demand for water, especially in arid and semi-

arid regions, such as Mediterranean environments (Egypt, Libya, Tu-
nisia, Algeria and Morocco), has forced farmers to use low-quality

water for irrigation, such as brackish water (Amer, 2010).

Soil of both Egypt and Tunisia along the Mediterranean see coast

undergo salinity stress problems particularly sandy and calcareous
soils. Although most areas depend on rain fed agriculture, however,

some are irrigated. The majority of soil-salt stress is often caused
from the accumulation of sodium, potassium and calcium soluble

salts which are mostly associated with chloride and carbonate an-
ions. One of the diagnostic problems in calcareous soil is the for-

mation of surface soil crust due to the capillary rise of soluble salts
especially in dry periods of soil moisture regime.
