What Causes Dryland Salinity
Dryland salinity occurs due to the replacement of deep-rooted perennial vegetation with shallow-rooted annual species.
Long fallows in a cropping rotation can also be a cause.
More water therefore enters the groundwater system causing the groundwater to rise and bringing salt stored in the soil profile to the soil surface.
This indicates a landscape ‘out of hydrological balance’.
