What is it?
Soil salinity occurs when salts accumulate in the soil profile to such an extent that plant growth is adversely affected.
It can occur in both dryland areas and in irrigated areas although the mechanisms of accumulation may differ between the two.
Areas of soil salinity can be identified by the presence of salt tolerant species see - Salinity Indicator Plants - A guide to spotting soil salting.
