摘要：Salinty of soils is the factor leading to the limitation of agriculture.
Due to the reduction of suitable fields farming is also reduced. As a
consequence farmers have to leave farms. This problem is specially
important in Egypt where cultivated land is limited to the Nile Valley.
A mineralogical and geological investigation of this phenomenon is
conducted at Heracompolis and surrounding areas showed the presence
of the following minerals as white salty coatings covering the surface of
local soils:
The absence of natural floods of Nile stopped due to the construction
of the Aswan Dam is the reason for the continuous elevation of the degree
of the salinity of soils. Evapotarion of water used for agriculture cannot be
prevented but the process of mineralization has to be stopped if Egypt
wants to avoid reduced food production.
