The soil salinization occurred due to irrigation is a concern in drier regions and not in humid regions. Consider the following statements

1.    In humid regions, there is enough precipitation to leach (wash) the salts below the plant root zone.

2.    In drier regions, higher temperature leads to higher evaporation of water resulting into leaving behind of salt on the surface of the soil.

3.    Soil salinization occurring due to irrigation can equally impact both humid areas as well as drier areas.
