describe how soil damage due to salinity could be reduced
Soil salinity 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.[3][4] A comprehensive treatment of soil salinity is available from the United Nations Food and Agriculture Organization.[5]
