Answer:
Soil salinity is the salt content in soil,
which is caused by improper irrigation. The process of increasing salt content
is termed as saliniation.
Causes
of Soil Salinity The high salt concentration of soil is caused by improper irrigation
method from a salt laden water table, when salt concentration in soil is
increased, than it get accumulated due to evaporation.
Human activities like fertilizing crop
is also responsible for salinity of soil. As fertilizer contain potassium,
which can form a naturally occurring salt-sylvite. Salinity of soil degrades
soil and vegetation. Normally the pH value of soil comprises between 2.2-9.7,
while above which thesoil is degrading by salt content.
