The most important factor in the emergence of salinity is the inability of
water entering the soil through precipitation or irrigation to wash away the
salts in the plant’s root zone effectively. The bare surface of the soil increases
water loss through evaporation, leading to an increase in the concentration
of salt in the upper layers of the soil. In these areas, it is essential to select
and implement plant species that are resistant to salinity and drought for
vegetation efforts.
