==Consequences of soil salinity==
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,<ref>{{Cite web  |title=Saltier waterways are creating dangerous 'chemical cocktails' |url=https://phys.org/news/2018-12-saltier-waterways-dangerous-chemical-cocktails.html |date= December 3, 2018  |website=phys.org |language=en |url-status=live |archive-url=https://web.archive.org/web/20230709172409/https://phys.org/news/2018-12-saltier-waterways-dangerous-chemical-cocktails.html |archive-date= Jul 9, 2023 }}</ref> 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 (agriculture)|leaching]] soluble salts out of soil with excess irrigation water.  [[Soil salinity control]] involves [[watertable control]] and [[leaching model|flushing]] in combination with [[tile drainage]] or another form of [[Drainage system (agriculture)|subsurface drainage]].<ref>{{Citation | title = Drainage Manual: A Guide to Integrating Plant, Soil, and Water Relationships for Drainage of Irrigated Lands  | year = 1993 | publisher =  Interior Dept., Bureau of Reclamation | isbn = 978-0-16-061623-5}}</ref><ref name="Waterlog">{{cite web |url=http://www.waterlog.info |title=Free articles and software on drainage of waterlogged land and soil salinity control |access-date=2010-07-28 }}</ref> A comprehensive treatment of soil salinity is available from the [[United Nations]] [[Food and Agriculture Organization]].<ref>Salt-Affected Soils and their Management, FAO Soils Bulletin 39 (http://www.fao.org/docrep/x5871e/x5871e00.htm)</ref>
