The consequences of salinity are
* Detrimental effects on plant growth and yield
* Damage to infrastructure (roads, bricks, corrosion of pipes and cables)
* Reduction of water quality for users, sedimentation problems, increased leaching of metals, especially copper, cadmium, manganese and zinc.  
* Soil erosion ultimately, when crops are too strongly affected by the amounts of salts.
* More energy required to desalinate
Salinity is an important land degradation problem. Soil salinity can be reduced by leaching soluble salts out of soil with excess irrigation water.  Soil salinity control involves watertable control and flushing in combination with tile drainage or another form of subsurface drainage. A comprehensive treatment of soil salinity is available from the United Nations Food and Agriculture Organization.
