what is dryland salinity
Dryland salinity. Dryland salinity is the build up of salts in the soil surface and groundwater in non-irrigated areas. Although salts are a natural part of the Australian landscape, dryland salinity refers to excess salt that affects soil, native vegetation, biodiversity, crops and water quality.alt near the soil surface makes it harder for plants to take water from the soil and eventually they die from dehydration. With agricultural crops, a yield loss of up to 30% can occur before the evidence of salinity becomes visible. Salinity rarely occurs in isolation from other natural resource problems.
