Understanding Salinization

What is a major consequence of increased salinity in farming land?

• Enhanced soil fertility

• Improved crop yield

• Abandonment of the land

• Increased biodiversity

Why does irrigation contribute to salinization even when using fresh water?

• Fresh water contains some salt

• Irrigation uses only saltwater

• Fresh water contains no minerals

• Irrigation prevents evaporation

What happens to the salt in the water during the process of transpiration?

• It evaporates with the water

• It remains in the soil

• It dissolves in the air

• It is absorbed by the plants

How does the rising water table affect soil salinity?

• It prevents salt from reaching the surface

• It dilutes the salt concentration

• It reduces the amount of salt

• It brings more salt to the surface

What is the ultimate effect of severe salinization on agricultural land?

• Improved water retention

• Enhanced soil nutrients

• Land becomes infertile

• Increased crop diversity
